Frequently Asked Questions (FAQs) About Finding the Source of Animal Smells in Buildings
Question: how to stop coyotes or dogs from urinating on a building
Have coyotes and dogs urinating on cedar wall near front door entrance. Have tried everything such as sprays, bleach, soap and water, obstacles, etc... nothing works. - C. Jones 10/10/11
Question: Tenants with many animals, hedgehog, crocodile, ferret, left terrible building odors
Having had tenants in a room for 10 months with snakes,rats,a hedge hog,crocodile, monitor lizard, and a ferret. The smell left behind is grim. We have had the carpet professionally cleaned but it is still not good. We could buy one but having spent money on cleaning which hasn't worked we obviously don't want to spend money on something that is then not going to be the answer. any advice? - Kyla 11/18/11
Kyla in my experience strong animal odors in carpets are very difficult to remove, in part because odors and urine or other materials penetrate both carpet and padding; most carpet cleaning, even steam cleaning, is just too superficial to be effective for deep odor contamination. I'd remove the carpeting, clean the floors, walls, ceilings, and then see how things smell. If odors persist you may need to
Question: problem with raccoons in the attic
We have NO ODOR. However there have been raccoons in the attic & I want to get someone to test the air quality for allergens related to the raccoons having lived in the house/attic. My father has a lung disorder & because there are NO ODORS I am wanting to dispel the notion that his lung problems are related to this. I am DEFINitely also in the process of having the raccoon problem alleviated. THANks - Donna 7/12/12
Donna I am skeptical that "air testing" or "air quality testing" is going to provide any definitive data on the presence or absence of an air quality issue due to raccoons whatsoever, nor am I confident that allergens you'd find would be related to raccoons in the attic. You might test the occupied space, including settled dust, for high levels of insect or animal allergens, including dust mites, animal dander, insect fragments. "Air tests" alone can give results that are "wrong" by several orders of magnitude when looking for particles.
When raccoons invaded our house through an open soffit we found them returning night after night to open a box of shiny Christmas ornaments that they considered great fun to bat around the attic floor. The remedy involved these steps:
If you're not up to these steps call a local pest control or animal control professional.
