How To Prevent And Control Rodents

As the temperatures outside begin to cool, rodent prevention and rodent control become issues all homeowners need to think about. How do I know what pest you have? How do I prevent and control rodents?

 Identifying Your Rodent Invaders

House Mouse

House Mouse

There are three main rodent types seen this time of year in the St. Louis area. The first is a house mouse. A house mouse has grayish-brown fur, with a tail equal to its body length. Homeowners often first know rodents are present due to the presence of droppings, making it important to know what to look for. House mouse droppings are roughly 3/8 inch long, black, and very hard.

Another rodent common now is the white-footed deer mouse. This mouse has brown fur with a white belly, as well as white feet. The droppings are similar to a house mouse, but since these mice are associated with Hantavirus, sweeping up their droppings on your own could be deadly.



The last rodent seen moving indoors this time of the year is the Norway rat. This rat has brown or gray fur, and a shaggy coat. A Norway rat’s ears and tail are covered in scales. The total body and tail length will average 8 inches to 10 inches. Norway rat droppings are about 3/4 inch long, black, and have a “hook” on one end.

How Did I Get Rodents in My Home?

Rodents seek warmth and food sources inside your house when the weather outside begins to cool. They look for tiny openings to gain entry into your home. Mice only require an opening as small as a dime to gain access; for rats, it is the size of a quarter.

Common entry points are:

  • Gaps where the gutter line meets the roof
  • Foundation cracks
  • Warped siding
  • Garages
  • Where utility lines enter the home
  • Sewer lines (access gained through floor drains or the toilet)

Preventative Measures To Take

house-miceIf you want to prevent and control rodents, there are steps you can take to deter their entry:

  • Professionally installed exclusion measures (e.g. sealing visible foundation holes)
  • Baited and monitored rodent stations outside of the home
  • Replace garage door seals
  • Keep indoor food areas clean of crumbs, wrappers, and dirty dishes
  • Contain trash in metal receptacles (plastic can be chewed)
  • Cover utility entry points
  • Do not use foam insulation to seal home, as rodents can chew through this

Why You Need Professional Rodent Control

For rodent prevention and rodent control, it is critical to employ a reputable pest control company, such as Holper’s Pest & Animal Solutions. Our expert service begins with a thorough inspection to develop a treatment plan for your specific problem.

It is important to note that all rodent droppings are a biohazard and should only be cleaned up by a professional using proper safety equipment, especially in the case of white-footed deer mouse droppings, which are linked to the deadly Hantavirus.

How Do I Keep Squirrels Away?

do I have squirrels in my houseThis time of year, it is not uncommon for pregnant squirrels to search for a perfect nesting spot. As you might imagine, a warm, cozy attic will hold a far greater appeal to a mama-to-be squirrel than an old tree does. Knowing that your attic is prime real estate for nesting squirrels, you have to wonder, “How do I keep squirrels away?” We are happy to share our top squirrel prevention tips.

Squirrel Prevention 101

A few proactive steps will help to keep squirrels away from your home:

● Keep tree limbs trimmed back so that none are overhanging your roof
● Install roof vent covers
● Install gable vent covers
● Install pipe stack covers
● Install dryer vent covers
● Seal gaps in the gutterline

The last item in the list is tricky, as gaps in the gutterline will not be visible from the ground. Finding those gaps to seal will require the expertise of a trained pest control technician.

An Ounce of Prevention: How To Keep Bats Away

The old adage says an ounce of prevention is worth a pound of cure. That couldn’t be more true in the case of bats. Knowing how to deter bats from roosting can save you worry, damage, and financial loss in the future. If you want to know how to keep bats away, you have come to the right place.

The Basics 

bat-opening-in-homeThe key to deterring bats from roosting is to block all possible entry points, which is much easier said than done. Bats can squeeze through holes that are ⅜ “ wide (the size of dime) and if they flatten themselves, they can squeeze through a gap that is ⅛” wide! Bats enter houses through eaves, overhangs, unscreened vents, and structural gaps. Occasionally bats enter a home through an open window or chimney. When you realize how tiny of an opening a bat can get through, you then understand how hard it is to spot potential entry points.

The first step in how to keep bats away is a thorough, professional inspection. Only a trained technician will know where to look and how to spot these miniscule entry points.

Why Should I Care About a Bat? 

Bats live in colonies of one to 300, so your infestation problem is rarely a bat, but bats! The result of this infestation will be the noises a bat makes (scratching, squeaking, and crawling in walls and attics) and the stains and odors created by urine and droppings (guano). 


Bat guano before cleanup.

Guano is a biohazard that should only be cleaned by the trained personnel of Holper’s with the proper safety equipment. Histoplasmosis is an airborne fungus disease that can grow in bat droppings (guano), but typically the guano must have contact with moisture, which usually isn’t present in an attic. Regardless, bat cleanup must be done professionally, with safety equipment, full face respirators, Tyvek suits, and HEPA vacuums due to the potentially deadly dust created by the guano.

Additionally, being a mammal, a tiny percentage of bats will contract rabies. Exposure to the rabies virus is decreased if you avoid contact with bats and keep all pets current on vaccinations. Your risk after exposure can only be assessed by a healthcare professional.  

How To Keep Bats Away 

Control involves sealing the entire structure, except where the bats are entering and exiting the building. Those spots are fitted with a one-way door so that bats are able to exit your building but they cannot re-enter. Once the bats have all left your home, the one-way doors are removed and the area is sealed, effectively bat-proofing your home.

Holper’s–Your BAT MANagement Experts! 

From diagnosing your bat problem, to the installation of one-way doors, to removing guano, to sealing the structure–one call to Holper’s Pest & Animal Solutions will get it done. When you want to keep bats away, call your St. Louis bat control/removal professionals at 314-732-1413 today!





What A Difference a Letter Makes: Moles vs. Voles

Most of us are aware that moles and voles are two different animals, but mole and vole identification is a completely different matter. What do moles look like? What do voles look like? How do we get rid of moles or voles?

The ABCs of Moles

MoleMoles are insectivores and are related to shrews. Adult moles are five to eight inches long and have brown or dark gray fur. Their noses and tails are pink. Even without functioning eyes, moles are still sensitive to light. Their broad, shovel-shaped feet have five toes and sharp, thick claws, making them highly efficient burrowers. Because they dine and dwell underground, they have few natural predators.

Moles eat from 70 to 100 percent of their weight every day. Because of their food needs, moles must cover a large area –and that translates to more yard destruction. Molehills and shallow tunnels are the results of this destruction. Molehills are circular dirt mounds, which surround vertical shafts. Molehills generally have round ripple marks left by every new load of soil pushed to the surface. One mole can dig up to 100 feet of raised-surface tunnels a day, creating a convex surface that make lawn mowing a challenge. The tunnels also create brown lines in your lawn when grass roots are damaged by burrowing activity/exposure to air. Seeing such a large area of damage, one might figure a whole army of moles is destroying your yard, when actually three to five moles per acre is considered a high population.

The ABCs of Voles

meadow-voleWhat does a vole look like? A vole is a blunt-nosed, short-tailed mouse, usually up to three inches long and charcoal gray. Herbivorous, voles prefer areas of lush vegetation, such as bulbs, tubers, herbaceous plants, and many types of grass. The size of a burrow system for multiple adults and their young will vary with the quality of the habitat, food supply, and population levels: In most cases it is only a few hundred square feet.

Voles are prolific breeders, so it doesn’t take long for a few voles to become hundreds of hungry voles. Voles chew their way through the thatch layer, which creates numerous shallow burrows containing underground nests of grass, stems, and leaves. Most damaging, voles will tunnel under snowpack, creating tunnel systems that only become apparent after the snow melts.

The most common sign of a vole infestation is the discovery of a single or multiple 1-inch holes in the yard, garden, or plantings. Also present might be a 1-inch wide trail, concave in relation to the ground. (This would look similar to a trail created by a bicycle tire.) Voles are primarily nocturnal–if you see them in daylight, it is indicative of a very high population.

How To Get Rid of Moles and Voles

According to Consumer Reports, trapping is the most successful method to rid your yard of moles. While different variations are available, the type that consistently achieves results is a spear trap. (Some homeowners mistakenly believe that treating their lawns for grubs will repel moles. Grubs are only a tiny percentage of a mole’s diet, so treating for grubs will have no impact on the moles–there is still plenty for them to eat.)
To minimize vole damage, the key is to manage the population before the numbers get too large. Mildly effective ways to discourage voles, such as planting flowers that are not palatable to them (e.g. daffodils and crown imperials), may help slightly, but the most successful technique to eradicate voles is a combination of professional services such as repellants, exclusion barriers, vole rodenticides, and trapping.

Trust Holper’s

Not every pest company gets to boast that they have “The Mole Hunter” as their president, but we do! Jeff Holper, aka “The Mole Hunter,” passes on his knowledge to all of our technicians so that your lawn will benefit as your moles are added to the more than 50,000 moles already caught by Holper’s Pest & Animal Solutions. For voles, the Holper’s process begins with a thorough inspection and is followed with a personalized treatment program combining the elements of professional services that your situation requires.

How Do We Get Rid of Rats in Walls and Attics?

Pizza Rat was all the rage online a couple of years back. A video of his triumphant trip with his spoils down the subway steps in NYC made him famous. We all laughed–because it’s funny when it’s somewhere else! That same sight close to home is not funny at all. And spotting one, or hearing one in our attics or walls, is no laughing matter! But how do we get rid of rats in our walls and attics?

How Did We Get Rats in The First Place?
Rodents seeking both shelter from the elements and additional sources of food may make their way into your home. Rats need only an opening the size of a quarter to find their way inside. There are many common entry points for rodents, such as cracks in your foundation, gaps where the gutter line and roof meet, siding that has warped, garages, and the spots where utility lines enter the home. Additionally, rats have been known to use the sewer lines as a way to get in through a toilet or floor drain. On its way in, a rat leaves a scent trail that creates an easy way for others to follow suit. As with so many things, prevention is the best way to protect your biggest investment–your home.

 Preventative Measures To Take

Before a problem begins, a trained professional from Holper’s Pest & Animal Solutions will come survey your home and yard to assess potential entry points for rats, as well as for other pests and wildlife. Here are steps to take in conjunction with the professional inspection:

  • Have exclusion measure professionally installed (e.g. sealing visible foundation holes)
  • Replace garage door seals
  • Keep indoor food areas clean of crumbs, wrappers, and dirty dishes
  • Contain trash in metal receptacles (not chewable plastic!)
  • Cover utility entry points
  • Do not use foam insulation to seal home, as rodents can chew through this.

Winged carpenter ant

Do I Have Termites or Ants?

You’ve spotted insect invaders but you aren’t quite sure what you have. All you know is that you want them gone…now! The key to removing them successfully is knowing what you are dealing with. If you have wondered “Do I have termites or ants?”, this blog will easily help you identify your pests, so that eradicating your problem can begin.

Termites vs. Ants










  • Termites are about ⅜ of an inch in length.
  • They can be dark brown or black in color.
  • If they still have their wings, the wings will be approximately twice the length of the body. (When termites swarm, they lose their wings, so a pile of wings nearby the insects will be another clue that they are termites.)
  • The antennae on termites are straight.

We actually have to differentiate between two types of ants, carpenter ants and odorous house ants, when we compare and contrast ants with termites.

Winged carpenter ant

Winged Carpenter Ant








  • Carpenter ants are ⅜ of an inch to ½ of an inch in length.
  • They can be black or dark red in color.
  • Some carpenter ants have wings, but the wings will only extend just past the end of the body.
  • The antennae are slightly bent.

Odorous House Ant









  • Odorous house ants are 1/16 of an inch to ⅛ of an inch long–much smaller than termites and carpenter ants.
  • They are brown or black in color.
  • They are primarily wingless.
  • The antennae will be bent, just like a carpenter ant.

I Know What I Have–Now What?

Treating termites requires a thorough inspection to discover the invasion extent and the damaged areas that require treatment. Treatment plans should be specific to your home based on the inspection findings, the linear footage of your house, and your home’s construction materials.

The only way to free your home of ants, or any other insects/pests, is to utilize professional treatment. Holper’s Pest & Animal Solutions has been trusted for over 30 years to treat St. Louis area homes using low-impact materials for your safety, as well as the safety of your pets. Holper’s uses a three-point attack on your ant infestation: treating the inside, treating the outside, and using bait outside of your home.

Do I Need Professional Mosquito Control?

With the temperatures cooling slightly this week, more St. Louisans will be spending time outside. After only a few minutes out there you will be reminded that mosquito season is still in full swing–and those guys are hungry! Besides the unpleasantness of mosquito bites, there is the very real threat of West Nile Virus, as it has been documented in the area. DIYers might think that a trip to the store will solve the problem, but in reality it is time to ask yourself an important question: Do I need professional mosquito control?

But I Like Being a DIYer!

There is an undoubtable satisfaction that comes from doing things yourself. In the case of mosquitoes, though, your only option as a civilian is a canned spray. These are usually of the fogger variety, providing no residual action, meaning you’ll have to use the fogger every time you have an event or every time you want to be outside. This is one time to put your DIY energy into another project and leave pest control to the experts.

Your greatest chance for safely enjoying your yard is monthly mosquito sprays from now through October. It is critical to have professional-grade materials applied by licensed exterminators if you want to eradicate all stages of the mosquito life cycle. Heat and rain lessen the strength of the spray over time, which necessitates a monthly re-application. Additionally, our popular garlic barrier application is an excellent repellent that many customers add on to their monthly yard sprays. Using Holper’s targeted approach for treating your yard can reduce your mosquito population by up to 97%!

Holper’s Provides Professional Mosquito Control

Holper’s Pest & Animal Solutions has been serving St. Louis for more than 30 years! Regardless of whether your problem is an insect, a spider, or invasive wildlife, Holper’s can solve the problem. If your goal is reducing the likelihood of West Nile-carrying mosquitoes in your yard, or just want to enjoy the out of doors without being the meal for hungry mosquitoes, then Holper’s yard treatments are the solution to your pest problem. Just call 314-732-1413 to schedule your professional mosquito control!

How Do I Get Rid Of Moles In My Yard Fast?

One single mole can ruin months of labor and untold dollars worth of care devoted to your yard. At the first sign of one, you’ll want to find out how to get rid of moles fast, to limit the damage. Why are moles so destructive, and how does a homeowner get rid of moles in the yard fast?

Well-Designed Yard Destroyers

mole-servicesMoles are excavation machines, with broad, shovel-shaped feet and thick, sharp claws. Their efficiency at burrowing is legendary. Consuming 70 to 100 percent of their weight daily, the enormous amount of energy they expend plowing through your soil foraging for food leaves exceptional damage in its wake. Due to their food demands, moles cover a larger area than most underground dwellers do–and that larger area equals more lawn damage for you. One mole can dig 100 feet of tunnels daily. Their raised-surface tunnels cause damage to your grass roots from the burrowing activity. Seeing the large area of damage, it will appear your yard is overrun with moles. In reality, three to five moles in an acre is considered a large population. Even so small a number can be difficult to capture lurking beneath the surface of your yard.

Is There a Mole Repellent

From a labor and monetary standpoint the answer is no. While spraying your entire yard and landscaping with multiple saturations of castor oil can have a repellent effect, the time involved and the cost incurred make this an unviable option. Similarly,  homeowners sometimes believe that treating their yard for grubs will drive away their moles. Unfortunately, because grubs only make up a very minute portion of a mole’s diet, treating for grubs will not yield the desired result. There will be plenty there for moles to feed on.

Yard Mole Control

Consumer Reports states that trapping is the most successful method to get rid of moles. A trap gives confirmation that every mole is removed. The trap form that routinely results in the highest success is a spear trap, which is set on the newest tunnels to increase your odds of a quick catch.

The Holper Difference

We are the only pest control company that gets to brag that we have “The Mole Hunter” as our president! Because of the expertise passed along to every technician by Jeff Holper, aka “The Mole Hunter,” your yard benefits with your moles added to the more than 50,000 moles already caught by Holper’s Pest & Animal Solutions. No matter what types of pests turns up in your yard, the professionals at Holper’s will solve your issue! Call Holper’s at 314-732-1413 to get rid of your moles fast!




Do I Have Bats in My Attic?

One of the most reviled wildlife pests is the bat. Just the thought of encountering one causes discomfort for many people. If you wind up with one, or a colony, in your home you will want to know quickly and have the situation handled ASAP with professional bat removal services.

So, do I have bats in my attic? How can I tell?

Ways to Tell If I Have Bats in My Attic

There are a few ways to tell if you have bats in the attic. The first way is to listen. If you hear scratching, movement, and especially an “eek, eek, eek” sound in the walls or above you, especially later at night, you’ve got at least one bat. A second clue is to look for piles of excrement (guano) on window ledges, or on the ground below gable vents and brick vents. The third way to tell if you have bats in the attic is to stand near the guano piles at dusk and look for the bats as they fly out to feed.

Why is A Bat a Biohazard?  


Guano is a biohazard that must only be cleaned by trained professionals using  proper safety equipment. Histoplasmosis is an airborne fungus disease that can grow in bat droppings (guano). Guano cleanup should always be done professionally using full face respirators, Tyvek suits, and HEPA vacuums due to the potentially deadly dust created by the guano.

A very small number of bats contract rabies, so avoid contact with bats and keep all pets current on vaccinations. Your risk after exposure can only be evaluated by your healthcare professional.

Professional Bat Removal Services

Bat removal involves sealing the structure, except where the bats are entering and exiting. Those entry/exit points are fitted with a one-way door so that bats can’t re-enter once they exit! It is best to implement bat removal services before the end of May or after the third week of August so you don’t trap a maternity colony in the structure. After all the bats leave, the one-way doors are taken down and the entry/exit is sealed, bat-proofing your home.

Holper’s–Your Professional Bat Removal Experts

From diagnosing your bat problem, to the installation of one-way doors, to removing guano, to guaranteed sealing of the structure–one call to Holper’s Pest & Animal Solutions will get it done. If your answer to “Do I have bats in my attic” is yes, just call the St. Louis bat removal professionals at 314-732-1413 today!
