Big Brown Bat
Small Brown Bat
There are eight species of bats commonly found in Ontario however only two come into contact with people because of their habit of roosting in buildings. These are The Little Brown Bat and The Big Brown Bat. The big brown bat is slightly larger and has less fur around its mouth and a smoother appearance to its face but unless the bats are side by side the two species are virtually indistinguishable to look at. Both are very common in Ontario however the big brown bat is more likely to infest attics in buildings and houses and commonly hibernate there all winter. Bat colonies can grow very quickly, doubling in size each year. Aanteater employees have seen colonies ranging in size from 1 to more than 300.
Bats play an important role in insect reduction, as one bat can kill over 2000 insects per night. A bat colony living in your dwelling though can cause a significant inconvenience, material damage and cause potential health problems.
Bats access building interiors through existing holes no bigger then ¼ inch in size.
Bats and Rabies
The vast majority of the recent human rabies cases in Canada and the U.S. have been caused by rabies virus from bats. Awareness of the facts about bats and rabies can help people protect themselves and their families. Unlike most other mammals in Ontario bats live in large colonies. Living in such close contact to one another drastically increases the risk of transmission throughout the population. The second characteristic is their tendency to harbour in our attics and buildings bringing them into direct contact with people. Tens of thousands of people in North America are treated for rabies each year after having been bitten by an animal that may have rabies.
How can I tell if a bat has rabies?
Rabies can be confirmed only in a laboratory. However, any bat that is active by day, is found in a place where bats are not usually seen (for example in a room in your home or on the lawn), or is unable to fly is far more likely than others to be rabid. Such bats are often the most easily approached. Therefore it is best never to handle any bat.
A bat colony living in your attic can carry potentially harmful infectious diseases and pests. Guano (bat droppings) in your attic may also be infected with a fungus called Histoplasma capsulatum, which causes the disease Histoplsmosis.
Pest Bat Removal and Control Services
The most effective method of removing a bat colony from your attic is exclusion. This is performed by the installation of a one way door over major points of entry and sealing off all other possible entry points on your dwelling. This procedure allows us to humanly and effectively remove the bats. Extermination or trapping bats is not an option as bats are protected in Ontario and extermination or trapping methods are impractical.
A technician will come to your house and do a thorough dwelling inspection to determine the entry points. He will then give you a detailed program to remove them from your house and then secure the entire structure against reentry. The technician will then deodorize your attic in order to remove the scent of the colony. This helps to reduce the attraction of other animals to your dwelling.
If you have a bat flying around in your house our trained technicians will catch the bat and contact the health dept to test the animal for rabies.
At certain times of the year nursing babies may be present in the colony. Removal of these babies is not possible as they cannot fly and never leave the interior. Using exclusion methods at this point will only get rid of parents and babies will be left to die causing odor and an impossible removal situation.
At Aanteater we believe the best pest control means removal of the underlying problem not simply masking the symptoms. If you have any questions please call your local 24 hour number or 1-888-390-7378. We would be happy to help.
