Understanding Raccoon Behavior and Biology
Raccoons (Procyon lotor) are highly adaptable omnivores native to North America. Their front paws contain four to five times more sensory receptors than human hands, allowing them to identify objects by touch—even underwater. This dexterity enables them to open latches, twist doorknobs, and manipulate garbage can lids. Raccoons are primarily nocturnal and have excellent night vision, aided by their dark facial mask that reduces glare. They are solitary except during breeding season (January–March in Colorado), with males roaming widely. Females give birth to 3–5 kits in April–May after a 63-day gestation. Kits remain with the mother until fall, which is why spring denning is so problematic for homeowners. Raccoons have exceptional memory: they can recall solutions to tasks for up to three years, making them persistent once they learn a food source or entry point.
Health Hazards: Raccoon Roundworm and Rabies
The most significant health risk from raccoons is Baylisascaris procyonis, a roundworm that lives in the raccoon's intestines and sheds eggs in feces. The eggs are microscopic, resistant to environmental extremes, and can remain infectious in attics for years. If accidentally ingested (e.g., via contaminated hands or dust), the larvae can migrate to the brain, causing severe neurological damage or death. Children are at higher risk due to hand-to-mouth behavior. According to the CDC, raccoon roundworm is considered an emerging zoonotic disease. Rabies is another concern: while raccoons are a primary rabies vector in the eastern U.S., cases in Colorado are more commonly associated with skunks and bats. However, raccoons in urban areas like Denver can still carry the virus. Avoid contact with raccoons, especially those acting unusually tame or aggressive. Always use professional cleanup services for feces removal.
Legal Regulations for Raccoon Control in Colorado
Colorado Parks and Wildlife (CPW) classifies raccoons as furbearers, which means they are protected but can be trapped under specific regulations. Homeowners may trap raccoons on their property without a license if they use a live trap and release the animal on-site (not allowed in many municipalities) or euthanize it humanely. However, relocation is heavily restricted: a permit from CPW is required to transport raccoons more than 10 miles, and many counties prohibit relocation entirely due to disease spread and high mortality. In practice, most professional pest control companies in Colorado hold the necessary permits to trap and remove raccoons. The best approach is always to hire a licensed professional who understands local ordinances. In Denver, for example, trapping requires a permit from Denver Animal Protection. Other cities like Colorado Springs and Fort Collins have similar rules.
The Raccoon Lifecycle and Seasonal Patterns in Colorado
In Colorado, raccoon breeding season peaks in February, with most births occurring in April and May. This timing coincides with spring snowmelt and warmer weather, making attics and chimneys attractive den sites for females seeking shelter. By June, kits are mobile but remain dependent on the mother until fall. Conflicts rise again in October–November as raccoons fatten up for winter and seek secure winter dens. During mild winters, raccoons remain active year-round, but in harsh mountain conditions, they may den for extended periods. Understanding this cycle is crucial for timing exclusion work: never seal a den site between April and August without first ensuring no kits are trapped inside. Professional removal during this period often involves a two-step process—eviction followed by delayed sealing.
What surveys and cost guides say about raccoon problems
Before you compare providers, it helps to know what independent surveys and published cost guides actually report about raccoon 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. Just 7.4% of residents who reported raccoons in their neighborhood wanted a small increase in their numbers, according to Puri and colleagues' 2022 survey of 1,006 people in one southeastern U.S. metro area (published 2024); the question was about neighborhood wildlife, not homes. Puri and colleagues' 2022 survey of 1,006 residents of one southeastern U.S. metro area, published in 2024, found that among people with raccoons nearby, 22% preferred a large decrease in the raccoon population; the figure describes attitudes, not raccoons in buildings. In the 2022 wildlife-perceptions survey by Puri and colleagues (1,006 respondents in a southeastern U.S. metro area, published in People and Nature in 2024), 23.4% of those with raccoons nearby preferred a small decrease, an opinion measure and not an infestation rate. When Puri and colleagues surveyed 1,006 residents of one southeastern U.S. metro area in 2022, publishing the results in People and Nature in 2024, 51% reported raccoons nearby; presence here means neighborhood sightings rather than infestation. In ConsumerAffairs' February 2024 survey of 2,000 U.S. respondents about home infestations (self-reported, pests and mold combined), 7% said they had moved out of a home for good because of pests, alongside 12% who relocated temporarily, general consumer figures rather than per-pest statistics. 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.
