Raccoon Removal in Maryland: Challenges and Solutions
Raccoons are arguably the most troublesome wildlife in Maryland. They are intelligent, strong, and dexterous—able to open latches, tear through soffits, and remove roof shingles. They often choose attics and chimneys for denning, especially in spring when females give birth to 3–5 kits. Raccoons are also primary carriers of rabies in the mid-Atlantic region; Maryland consistently reports raccoon rabies cases. Professionals use humane live traps baited with marshmallows or cat food. After removal, exclusion is critical: raccoons will return if entry points are not sealed with heavy-gauge steel mesh. Attic restoration is often needed due to urine-soaked insulation. Maryland requires raccoons to be euthanized if trapped, not relocated, because relocation spreads disease and disrupts ecosystems. A professional will dispose of the animal humanely and legally.
Bat Exclusion: Timing, Regulations, and Health Risks
Bats are protected in Maryland because they are vital for insect control and are threatened by white-nose syndrome. The Maryland Department of Natural Resources prohibits exclusion during maternity season (May 1–July 31) when flightless pups are present. Exclusion during that period can trap and kill young bats, which is illegal and inhumane. The only legal approach is to install one-way exclusion devices that allow bats to exit but not re-enter, sealing all other holes. This must be done in late winter or early fall. Bats roost in attics, behind siding, and in chimneys. Their guano accumulates quickly and can harbor Histoplasma capsulatum, a fungus that causes histoplasmosis (lung infection). Cleanup requires HEPA vacuuming and disinfecting. Professional bat exclusion typically costs $1,000–$2,500 and includes a guarantee that bats won't return.
Squirrel Intrusions: A Year-Round Nuisance
Gray squirrels are abundant in Maryland suburbs and forests. They enter homes through gaps as small as 1.5 inches—chewing through wood, vinyl, and even aluminum. Squirrels are active year-round, but intrusions spike in late summer (juveniles dispersing) and early winter (seeking warmth). They often nest in attics, causing damage to wiring and insulation. A single squirrel can cause thousands of dollars in damage if it chews through electrical wires, creating a fire risk. Squirrels are not protected in Maryland, but trapping and removal must be humane. Exclusion is the best prevention: seal all openings with steel mesh, and trim tree branches. One-way doors can evict squirrels already inside. After removal, check for babies—squirrels often have litters in spring and fall. Professional removal averages $300–$500.
Skunk and Opossum Control: Unique Challenges
Skunks are known for their spray, but they also dig under decks, porches, and foundations, creating burrows that can undermine structures. They are attracted to grubs in lawns. Skunks are carriers of rabies and distemper. Trapping skunks requires careful technique to avoid triggering a spray; professionals use covered traps and dark cloths to calm the animal. Opossums, on the other hand, are often misunderstood. They are docile, rarely carry rabies (their body temperature is too low), and are beneficial because they eat ticks (up to 5,000 per season) and other pests. However, they will den under sheds, decks, and in crawlspaces. Opossums are transient and often leave on their own if not threatened. Exclusion—sealing access to crawlspaces and under decks—is the best long-term solution. Both skunks and opossums can be trapped and relocated in Maryland, but check local ordinances.
Groundhogs (Woodchucks) and Their Damage
Groundhogs are prolific diggers that can undermine foundations, patios, and retaining walls. Their burrows can extend 30 feet with multiple entrances. Groundhogs are active during the day, especially in spring and summer. They are not protected in Maryland and can be trapped. Exclusion involves burying heavy-gauge fencing at least 2 feet deep and bent outward at the bottom to prevent digging. Groundhogs are strong and can push through weak barriers. Professional removal costs $250–$500. After removal, fill the burrow with gravel and soil to prevent other animals from moving in. Groundhogs are also known to climb, so protect garden areas as well.
Evidence check: wildlife encounters, DIY attempts and professional help
Before you compare providers, it helps to know what independent surveys and published cost guides actually report about wildlife problems in U.S. homes. None of the figures below come from this site's own customers; each carries its source, date and population so you can weigh it yourself. The Illinois Natural History Survey's 2000 survey of homeowners in a large northeastern Illinois metro region, reported in 2001, found that about half (51%) fed wildlife on their property, even as 58% reported wildlife problems; the results are local and dated. For a suburban homeowner, nuisance wildlife is closer to the norm than the exception: 54% of northeastern Illinois homeowners in the Illinois Natural History Survey's (INHS) 2012 survey (reported 2013) had a wildlife problem the prior year, though the figure is regional, not national. Among the 518 action-takers in the Illinois Natural History Survey's (INHS) July to October 2012 survey of homeowners in the greater metropolitan area of northeastern Illinois (reported 2013), 38.0% said they had used sealing cracks and openings, one of several options they could select. Nine percent of homeowners in a large northeastern Illinois metropolitan region said they had received information about handling wildlife problems, according to a 2000 Illinois Natural History Survey (INHS) study; the finding is historical and local, not a national figure. If you have been ignoring scratching in the walls, you are not alone: 17% of the 2,000 U.S. respondents in ConsumerAffairs' February 2024 survey of 2,000 U.S. respondents reported taking no action against pests, though the self-reported, pest-and-mold survey offers context, not an infestation rate. Because every figure above has a stated population and date, you can cite it when comparing providers. What none of them can tell you is what your specific property needs; that still takes an on-site inspection.
