What does Toronto Pest Control Services do to eradicate bats?
Big Brown Bat
The most effective method of resolving a bat infestation in your attic is by exclusion. Toronto Pest Control Services will send a technician who will complete a thorough inspection of your roof. The technician will identify the major entry points of the bats and any other cracks large enough that bats may be able to get in through. Bats can enter through any holes that are about 3/8 of an inch in size or larger. He will write a free estimate for you detailing all the work necessary to permanently exclude the bats from your house. In order to perform the exclusion the technician will then attach one way doors over their entry points which allowthem to come out. Bats must leave to eat and drink every night. When they return they are unable to reenter your attic through the one way doors and are locked out. The bats will then fly around and try to find other entry points to gain access back into your attic. The technician will also seal up all thecracks identified in the inspection where the bats could possibly gain entry backinto your attic.
There are certain periods during the year, where this service is unable to be rendered. During baby season, which is May to July, bat babies are being born and are unable to fly and leave the nest. Depending on the type of bat, it could take 2-4 weeks for them to be weaned. If we were to do exclusion work during this time, the babies would be unable to exit the attic and would most likely die. Since bats are a protected species and it is illegal to kill them, there is nothing that can be done until the young are able to fly which is not usually to the end of July. If you have an established colony of bats in your attic it may be necessary to clean up any bat guano (droppings) in your attic. Toronto Pest Control Services does provide an Attic Restoration service which we are able to provide you with a quote once the bats have been removed from your attic.
FREQUENTLY ASKED QUESTIONS
Is there a colony of bats in my attic?
Little Brown Bat
In Ontario there are 8 species of bats, however, only two types of bats, the Little Brown Bat and the Big Brown bat invade our attics. Both of these types of bats create maternity colonies during the summer months which are colonies of females. These maternal colonies have their young anywhere from mid-May to the first of July. Baby bats do not leave your attic for 4 weeks after being born. If you find a bat in your house or you can hear them in your attic you most likely have a bat colony in your home as the only bats that invade your attic are bats that colonize. If you see a bat in your home during the winter months, then you almost certainly have a colony. Bats hibernate during the winter months, with the Little Brown Bat travelling to a winter hibernation areas which could be close to its summer home or a few hundred miles away. Little Brown Bats prefer to winter in caves and mines while the Big Brown Bat will often stay to hibernate within your attic. Therefore if you do see a bat in your house during the colder months, it is most likely a Big Brown Bat that has colonized with others in your attic and inadvertently been awakened from hibernation.
If I find a bat flying in my house, what do I do?
If you find a bat flying around in your house, you have two options. The first option is to open the windows and close the door to the room where the bat is flying around. Once you open the window, dim or turn off the lights. This gives the bat an opportunity to leave your home without you having to come in contact with it. Your second option is to close the door to where the bat is flying around to stop it from going into the rest of your house. Most importantly do not take your eyes off of the bat. The bat will grow tired and find a place to rest. One of the most common areas for a bad to rest is on top of a curtain rod above a window. The bat may also try to hide somewhere to keep out of site. Once the bat has found a resting place and you have your eyes on it, call a Wildlife Professional. We cannot stress enough that you must keep your eyes on the bat because if a Wildlife Technician comes out to your home to remove the bat, but you donít have eyes on it, it is very unlikely the Wildlife Technician will be able to locate it. If you have gloves, you can try putting a plastic container over the bat and sliding the lid onto it. If the bat has been flying around where people sleep you should call public health. Once the bat has been caught you should bring it to your local animal control office and it should be tested for rabies. Bats do bite, and their teeth are like needle points, which sometimes make it difficult to know if you have even been bitten. As bats are carriers of rabies it is always important to have a bat tested if it has been flying around in your home especially where people sleep.
Why is there a bat in my house and how did it get in?
The Little Brown Bat and the Big Brown Bat are the most common bats found in Ontario and these are the bats that infest your attic. They do so especially during the summer months so they can form their maternity colonies where they have their young and wean them to adulthood. The bats will leave your attic at night to forge for insects as this is the best time to find their food. Bats can see, but use echolocation to navigate. The bats will also use air currents to find their way around inside your attic or walls at night. What causes a bat to come out into your living space is sometimes warm air from your basement creates a draft inside your walls that the bat will follow to find its way out and will instead accidentally end up crawlingdown your wall and pop out somewhere in your basement . The bat will then panic and try to find a way out. Since bats spend a lot of time in caves, their natural instinct is to fly upwards and therefore they usually end up upstairs.
What disease risks do bats pose?
Bats do pose a disease risk to humans as they have been implicated in a number of human diseases although rabies has received the greatest attention from public officials. Rabies is a disease caused by a virus that attacks the central nervous system of mammals. Rabies is spread through the contact with saliva of an animal that is infected. Each of the 8 species of bats found in Ontario has their own strain of rabies. The most common strains of rabies are found in the Little Brown Bat, the Big Brown Bat and the Silver-Haired Bat. Since the Silver-Haired Bat tends to be reclusive it is very rare that it ever comes into contact with humans. While humans contracting rabies from a bat is a concern, it is a relatively rare occurrence. Since 1925, in Canada, only five of the 26 cases of rabies in humans have been because of contact with an infected bat. In Canada the last fatality of a human after contracting rabies from a bat was in Alberta in April of 2007, it was a 73 year old man. The primary source of rabies exposure from bats is through the careless handling of them. Though Southern Ontario has a large number of bats, rabies is quite infrequent. There have been 314 bats confirmed with rabies in Ontario from 2001 to 2005. Of all the bats submitted because they were acting strangely, dead or may have come in contact with a human or a pet, only 2% had rabies. This percentage would be much lower in the overall population of bats in Ontario. Even though the overall percentage of bats with rabies is low, any bat that is encountered should be considered rabid unless it has been captured and tested to prove otherwise.
How can I tell if a bat has rabies?
There are some signs to look for that will help to indicate if a bat has rabies. Bats are nocturnal creatures, so if you see one flying around during the day, this may be a sign that they are sick. When some bats have rabies, they may fly erratically or may not even be able to fly at all. Another sign of rabies is if you see a bat crawling on the ground it is either sick or may be injured. If the bat has rabies it rarely becomes aggressive unlike other mammals like raccoons.Donít ever handle any wild animal but if youmust handle a bat, whether it is showing signs of injury or disease or is healthy, always wearheavy gloves and if possible use tongs or forceps to pick it up. If the bat has come into contact with pets or humans, contact your local health unit.
Why are bats a protected species?
Bats are a protected species and it is illegal to kill them because they are beneficial to our society because of their appetite for insects. Each night during the summer one bat can consume hundreds of flying insects. Bats use echolocation which means they send out signals and when the echo of that signal bounces back they are able to identify where objects are located. This is how they locate their food. Bats only eat insects, and often they catch them during flight. The mosquito population can be slightly reduced because of the bats feeding behaviour. Bats however are very beneficial to the agriculture community. A single bat colony can significantly reduce the number of insects which may drastically reduce the need for pesticides on crops. Bats will eat insects that damage agricultural industries and can spread plant disease such as: spotted cucumber beetles, frog hoppers, leaf hoppers and other species of insects. With bats eating these insects, corn yields significantly increase which increases profitability.
Little brown bats have an adult wing span between 9 to 11 inches and a body length between 2-4 inches. Their colour can range from a dark brown to reddish brown or pale tan. The big brown bat has an adult wing span between 13-16 inches and their body length can range from 3-6 inches. Their colour can range from light brown, to reddish brown or dark brown.
Bats usually breed in the late summer or early autumn. The female will store the sperm until April.In April she ovulates and the egg becomes fertilized and implanted. Both species ofbrown bats give birth in late spring to early summer. Big brown bats have twins and little brown bats have a single baby each year. The age of weaning for Little Brown bats is 14 days while for the Big Brown bat it is 3-4 weeks. The Little Brown bats life span can be as great as 31 years; however their average life expectancy in the wild is limited to probably only a few years. The Big Brown batís life expectancy is around 18 years.
Bats are located throughout most of Ontario but they prefer to be near fresh water where they can forge for insects. The Little Brown Bat and the Big Brown Bat are the most common bats found in and near buildings in Ontario. The Little Brown bat makes summer colonies that may include hundreds of bats and they commonly roost in dark, hot attics and other roof spaces. There colonies are referred to as maternity colonies. Their colonies can also be found in tree hollows, beneath bridges, beneath shingles and siding and in caves. The Big Brown Bat also makes summer maternity colonies but they may include a dozen or so bats up to a few hundred. The Big Brown Bat likes to roost behind chimneys, in attics, barns, hollow walls, in enclosed eaves and behind shutters or unused sliding doors. During the winter months the Little Brown Bats and Big Brown Bats will hibernate. The Little Brown Bats will migrate to winter roosts most likely in cave or mine structures. Their winter roosts can be near their summer roosts or up to a few hundred miles away. The Big Brown Bat sometimes stay in the same roost all year round.
