Surrounded by the rich agriculture of the Cumberland Valley, Carlisle is known for producing dairy, beef, and hops as well as a diverse array of crops grown on smaller boutique agritourism farms that participate in farmer’s markets and pick-your-own activities.

Where there are livestock and crops, there are nuisance animals cohabitating and benefitting from the food and shelter of barns, residences, and larger local institutions such as the U.S. Army War College, Dickinson College, and the Penn State Law School.

Critter Control is a full-service nuisance wildlife company that not only gets rid of pests but repairs the damage caused by a current infestation while helping to prevent future ones.

Critter Control Wildlife Removal Process

Critter Control is here for you every step of the way in the wildlife removal process. From inspection to removal—and even exclusion and repair—we have the services you need to get rid of raccoons, rodents, and other nuisances fast. First, we identify the animal on the property, then use humane methods to remove the animal and secure weak points where more could enter. If damage has been done, we can make those repairs for a complete restoration. Contact a Critter Control office near you today.


Wildlife Inspection

During the inspection we try to ascertain how many animals there are, where they are located, and how they got in. Based on what you have seen, heard and smelled, we start the inspection where you have noticed signs of animal activity. Evidence of animals inside your home include nests, dens, feces, and animal tracks. We investigate the exterior of your home looking for possible entry points, any evidence of animal damage, tracks, fur, animal waste, or rub marks.



We use several methods to humanely remove the animal from your home. Depending on the species, the number of animals, and the condition of your property, we develop a custom wildlife removal plan. Humane wildlife removal strategies include animal traps, one-way doors, and repellents. Once we guarantee all animals are gone, we implement exclusion techniques. Exclusion techniques provide a safe, long-term solution to nuisance wildlife in your home. We create barriers to prevent animals from getting to resources. We only apply exclusions once we are sure all animals are gone from your home.


Exclusion and Repair

Wildlife will damage your home. Exclusion techniques repair any damage the animal causes getting into your home. Inside your home, animals build nests and dens out of readily available material. They will create runs through the insulation. Rodents will gnaw on anything including electrical wires and pipes. Animals can also spread diseases. We apply sanitation agents to clean up feces and urine. Mammals can host pests like fleas, ticks, and mites. Ectoparasite treatments exterminate those pests so you don’t become their next host.

Rodent Removal

Rats and mice are two of the most common and destructive pests found in homes, commercial buildings, farm outbuildings, and their open fields throughout the U.S. They have learned that close proximity to humans is synonymous with steady access to food, water, and warm shelter.

Able to squeeze through an opening as small as one-quarter inch, they will contaminate food, chew through walls, electrical wires, storage containers, and more to make their nests and sustain their comfortable lifestyle.

Rats and mice breed throughout the year. A single mouse can produce about 300 babies in a lifetime. Should you suspect a rat or mouse problem, a call to Critter Control immediately can help save you, your family, or your growing business from the serious health and damage risks they bring.



During a rodent inspection, we thoroughly inspect your attic and provide a complete exterior home inspection. The most common signs of rodent activity are gnaw marks, feces, rub marks, nesting material, runs in insulation material, and small entry points.

Trapping and Removal

Rodent Trapping

A Critter Control wildlife specialist will create a strategic trapping plan to remove the rodents found in your home. Critter Control specialists may use snap traps and live traps to capture and remove mice and rats. Rodent trapping can usually takes between five to fourteen days.



The best way to reduce the possibility of letting unwanted rodents into homes is to seal possible entrances. Exclusion methods include caulking cracks in foundations, capping chimneys, and installing mesh covers over vents and crawl space entrances. We also strongly recommend a maintenance service. Rodents have front teeth that continuously grow, which means they can gnaw a new way back into your home.

Raccoon Removal

Raccoons are active all year long. While you sleep, they are out scavenging for food and looking for new places to live. There are plenty of food sources in Carlisle and all of Cumberland County. Raccoons eat just about anything, from restaurant scraps and pet food to garden crops and chickens. Their hands resemble human hands and allow them to turn doorknobs, open storage bins, and climb trees, chimneys, and poles.

Raccoons have a permanent mask and banded tail. They would be cute if they weren’t so destructive. They will do what they can to get into parts of your house they see fit to sleep and give birth to pups. If they must rip, tear, or break something to get to that spot, they will. Raccoons make lots of noises, like whimpers, growls, and screams. They leave feces and urine nearby their shelter.

Before trying to remove a raccoon from your home by yourself, remember they can carry diseases, and if threatened, they may bite. Calling nuisance wildlife animal control experts is recommended. Critter Control’s three-step process works well for raccoon removal.



During the inspection, we determine the severity of the raccoon infestation. We look for physical evidence like footprints in or around the home, stains from raccoon feces and urine. On the exterior of the house, we look for damage like scratches on boards, broken vents and screens, ripped apart shingles, destroyed soffits, and every possible entry point.

Trapping and Removal

Raccoon Trapping

Live trapping is one of the most efficient ways to get rid of a raccoon. Depending on the situation, a one-way door or excluder valve can be installed. An excluder valve works by allowing the raccoon to leave but blocks its reentry. The choice of device is largely dependent on the season and location of the raccoons on your property. Direct capture is not commonly used because raccoons are a rabies vector species. If we must trap, we place traps strategically to safely catch the raccoons and we check traps frequently, based on state laws.



We provide a wide range of repair and restoration services. We can repair raccoon damage like broken screens on vents and chimneys and broken boards on decks and porches. It is essential to apply cleaning agents and ectoparasite treatments on areas inhabited by raccoons.

Opossum Control

Opossums are the only native North American marsupial. Their young develop inside their mother’s pouch, much like a Kangaroo. After a few months, the young are ready to leave the pouch and can often be seen clutching to the mother’s back as she travels in search of food and shelter.

Opossums are beneficial, as they eat many different types of insect pests, but they can cause damage when they choose to den in your attic, garage, crawl space or under your patio or shed. They’re famous for playing dead when approached, but they do have 50 teeth, so don’t push your luck. Call Critter Contro of Carlisle to address any issues you have with opossums.



Opossums can be found inside attics and basements or outside under decks and sheds. Common signs include unique paw prints and feces. Opossums are docile and usually easy to spot.

Trapping and Removal

Trapping & Removal

Opossums can be lured into cages for live capture. If it is maternity season, we follow all guidelines for removing mother and newborn opossums. We will seal entryways into the building to prevent opossums from reentering in the future. Opossums can be kept from getting under sheds and decks by installing fencing around the bottom edges and burying the fence underground.



Broken screens on chimney and roof vents are replaced with sturdier materials, and we properly seal all entry points, including crawlspaces. We clean and deodorize areas of opossum activity. Exclusion may include eliminating sources that attract bugs, like nighttime lighting, stagnant water, and livestock poop.

Squirrel Removal

Five squirrel species are residents in Carlisle: the eastern gray, American red, fox, northern flying, and southern flying squirrels. Two interesting facts about their physiology are that they can leap ten times their body length, and they can turn their ankles 180 degrees to face any direction when climbing.

Although most people appreciate their cuteness, they are part of the rodent family and will wreak havoc in your attic, basement, or crawlspace. As with rats and mice, squirrel teeth never stop growing throughout their lives. Gnawing is the way they keep their teeth to a manageable length. Squirrels will gnaw on electrical wires creating a fire hazard as well as many other materials stored in an attic. They also soil insulation with their droppings, urine, and parasites.



Wildlife specialists look for signs such as chewing on, in, or around your home, small openings leading to the attic or the crawl space, droppings, and debris like nuts or nesting material. Beams, wires, pipes, and insulation may all show signs of damage from squirrels.

Trapping and Removal

Squirrel Trapping

Live trapping or one-way doors are the most effective and humane ways to get rid of squirrels. One-way doors should never be used during birthing seasons (Spring & Fall), so our specialists will decide which is the best tool for the job. If we have to trap, we place traps strategically to safely catch the squirrels and check those according to state laws.



We can restore your home or office by squirrel proofing all entry points after we have removed the offenders. We can also clean-up the nesting sites and remove any debris, food, feces and soiled insulation.

Bat Removal

Pennsylvania is home to nine bat species: big brown bat, little brown bat, tri-colored bat, hoary bat, Indiana bat, small-footed bat, silver-haired bat, northern long-eared bat, and the red bat. All are insectivores, helpful in the control of insects detrimental to residents and farmers.

Female bats will set up roosts in barns, sheds, attics, and window shutters, where they will hibernate for the winter and give birth to their pups in the spring. All bats are protected in Pennsylvania. The northern long-eared bat, tri-colored bat and little brown bat are endangered because of the proliferation of white-nose syndrome. Not only is bat extermination illegal, but you also cannot remove bats until August.

While bats are woefully misunderstood and quite beneficial, they do harbor parasites, and the mold that grows in their feces can cause Histoplasma, so it is important to get rid of them and seal up places through which they can get in.



We perform a full interior and exterior inspection and search for signs such as rub marks, guano, a strong scent of ammonia, and small openings. The most common sign is the accumulation of guano (feces).

Trapping and Removal

Bat Removal

The most effective and humane way to remove bats is by utilizing a bat valve in conjunction with a full home exclusion. A bat valve allows for bats to exit your home but not re-enter. We follow all local ordinances for humane bat removal. We will never abandon flightless pups in your attic.



After removing the bat valves, we seal the entrance hole(s) so bats can no longer enter your home. If there is substantial guano in your attic, you should consider taking advantage of our attic remediation services to remove the soiled insulation and replace it.

Bird Control

Birds are mostly beloved creatures, known for their beautiful colors, graceful flight, and beautiful songs. But there are some species of birds that are impossible to love, such as Canadian geese, starlings, pigeons, and even woodpeckers!

When geese descend upon a yard or field, they can smother it with feces within very short order. Protected by federal laws, adult geese, their nests, eggs, and young cannot be harmed without a permit.

Woodpeckers are a sometimes nuisance when they peck incessantly on the siding of a house. This behavior, done mostly as a mating call, can result in chipped siding and paint and dents and holes along the trim. This damage can become costly to repair.

Starlings are quite common in Carlisle, where their large flock creates a lot of noise. Their droppings smell foul, and they can build their nests on home or barn exteriors.

While it is hard to get rid of birds, Critter Control experts can deter these birds from your property and advise on habit modifications that will make your property less attractive to them.
