Cowleys Pest Services Case Studies: Bat and Raccoons destroy attic insulation in E. Windsor

Wednesday, August 26th, 2015 by John Rockhill


This Windsor homeowner had suffered through both a bat and raccoon infestation in his attic. These infestations are more than a nuisance; they can be a bona fide health hazard. Wildlife can transmit diseases such as rabies and histoplasmosis. The rabies virus is contracted through bites; histoplasmosis can be from breathing in contaminated fungus air spores as a result of their droppings. 

The most common sign of a bat infestation is probably their guano (bat feces). Although bats are small creatures, because of their numbers, copious quantities of guano can quickly accumulate. Bat guano resembles rodent droppings. Bat guano tends to cluster as it piles up beneath the exit of the roost or under eaves and overhands, and is often shiny, speckled because of their insect diet. Bats often leave milky white urine stains on windows, and smears of grease and dirt from their coats.Besides the stains and odors, there are various animal noises, such as squeaking and scratching, when these nocturnal creatures are up and about. 

Raccoon infestations are on the rise and have proven themselves highly adaptable to human habitats. People provide them with plenty of food from garbage cans and dumpsters, and they like to make themselves comfortable inside human dwellings, especially in crawl spaces and attics. Raccoons have razor-sharp claws and teeth and can become aggressive if they feel threatened, especially moms who are protecting their litter. Raccoon droppings resemble those of a medium-sized dog. Other raccoon signs are noises, track markings, and hair deposits. For bats, raccoons, or any nuisance wildlife, one of the most important steps after removal is locating and closing the access points used for entry in the home to prevent a re-infestation.

Depending on the length of the infestation and number of invading wildlife, there can be significant property damage. Besides chewed electrical wires that are a potential fire hazard, insulation often takes a beating. Once wildlife takes up residence in the attic, a good portion of the insulation can be ruined beyond repair. The insulation is not only torn and shredded, but also is saturated with urine and droppings. The odors are so strong they can permeate the entire house. 



This Windsor homeowner decided to use Cowleys to install TAP Pest Control Insulation, an environmentally safe, ENERGY STAR designated, UL classified, fire retardant loose-fill cellulose insulation that is made primarily from ground-up newspaper. TAP stands for Thermal, Acoustical, and Pest Control. This insulation not only offers superior thermal and acoustical (sound-deadening) properties, but also offers a proven method of pest control. The paper fibers are treated with a borate solution, which, while harmless to people, is lethal to certain insects including ants, beetles, and termites.

We first cleaned out the old, soiled insulation, cleaned and deodorized the attic and then installed TAP.

This homeowner had first-hand experience with the quality of Cowleys services, and was happy that he could continue to rely on Cowleys for the insulation work. Now, this homeowner is enjoying a living space that is free of wildlife odors, and has the peace of mind of expertly-installed top-quality attic insulation that will save him money for years to come on his heating and cooling bills.
