Bat Exclusion

In today's culture, the bat is commonly associated with what goes "bump" in the night. These winged furry mammals are almost universally feared by people despite the advantages of their presence. Primarily, bats are an excellent form of mosquito control as a bat may eat up to half its body weight in small flying insects in one night. Bats are the only mammals to have the natural gift of flight. Bats are commonly seen hanging upside down as this is their preferred sleeping orientation. In Ontario the most common species of bat you might encounter are the Small Brown Bat, Big Brown Bat, Eastern Pipistrelle, and the Hoary Bat.

Below we have provided you with basic information on the most common bats in Ontario.

Where do Bats Live and What do They Eat?

Bats usually feed on small insects like mosquitoes. While some bats may eat fruit or feed on livestock, these species are not found in Canada. Bats typically live in caves, trees, buildings, attics, and under eaves of a roof. Anywhere a bat may hang upside-down is a potential home. Bats are difficult to keep out of buildings as they can squeeze through the tiniest of holes. If you are having a bat problem Nimby professionals will provide immediate assistance.

Are Bats Dangerous?

Since bats in Canada eat insects, they keep their interactions with humans to a minimum. There are two major health risks. First, bat droppings, know as bat guano, are a health hazard. Bat guano, like many bird droppings, are nitrogen rich and are a home to bacteria and fungi that may be hazardous. Specifically, a fungus called Histoplasma capsulatum is common to bat guano and several bird droppings. This fungi may cause Histoplasmosis (Darling's disease), which is primarily a lung disease. Occasionally this disease may spread to other organs and can be fatal if left untreated. The best way to prevent contracting this disease is to avoid bird and bat droppings, especially in your living or working environment.

Secondly, there may be risk of rabies transmission if there is contact between a human and a sick bat. The occurrence of rabies in the bat population is very low, less than two percent according to the Government of Ontario. However, any bat encountered should be considered rabid unless proven otherwise. Twenty-six cases of human rabies have been due to contact with a rabid bat since 1925. Typically, a rabid bat will not exhibit aggressive tendencies like other rabid mammals. A rabid bat will lose the ability to fly well or at all. If you find a dead or dying bat it should be treated as if it were rabid and submit them to the Canadian Food Inspection Agency for testing if people or animals may have had contact.

While bats are harmless creatures on their own, diseases they carry can be hazardous to your health. If you have bats living in your home or workplace, call a Nimby professional.

Bat Exclusion

The best way to exclude bats from your living environment is to prevent their entry. However, this can be difficult when bats can slip through holes less than a half inch. The best way to remove bats from the building is to trap them out by sealing the hole when they leave to feed at night. Nimby professionals delivery an effective and lost cost solution because they can work at night when bats are active.
