Bat removal, bat control and bat relocation during the Fall months is often the best times to complete bat removal exclusions. During the beginning of fall all juvenile pups are in full flight and aren’t at risk of being trapped into their dwelling area (attic, eves, walls, vents, etc.).  Fall months are often cool, but most times the nights are still warm enough for all the bats to leave their roost for food and water.  Once the temperatures drop below 40 degrees at night and frost line hits the food source will die out and the bats cannot survive without relocating or hibernation. Bats will tend to move from the rafters of your attic, the soffits, and outside vents down underneath the insulation to find an area above 40 or 50 degrees where it is most comfortable for them to survive.

Because the temperatures are so up and down during the fall months it is very important not to remove the exclusion devices installed on your home until late spring or early summer of the following year. Also there is no guarantee during the Fall months that the bats will be excluded from their roosting area. We continue to monitor the flight activity of the bats during these months.

Having your home bat proofed and exclusion work done during the Fall months can also be beneficial to the home owner because any open airways into your home can be sealed to cut down on energy bills.  During home inspections our technicians can make you aware of your insulation value where we can offer more insulation to make your house more energy sufficient.  Also if you have asphalt shingles they won’t be at risk of being ruined because of being too hot when our technician are moving around on your roof top sealing entry points.

How do you get rid of bats during the Fall?

Most bats in the attic in Michigan live beneath the insulation or in wall cavities where it’s warm. Some bats in the attic can be removed and relocated by hand. Not all bats are ever found in any certain attic. The one and only way to remove bats during the Fall or any month for that matter is through a live bat exclusion.

20140516_100857.jpgBat Removal Process in the Fall without Detail is a 3 step process:

  1. Inspection: Locating entry points and other potential entry points.
  2. Live Bat Exclusion: Installing one way doors and bat proofing the rest of the home.
  3. Return visit: Re-inspect the home and remove one way door after a minimum of a week. We keep our doors up until late fall.

The length of time it takes bats to exit your home varies depending on the temperature and feeding patterns. During most fall months, getting rid of bats usually takes between one and three weeks.

Improper Bat Removal Techniques

The process mentioned above is the only acceptable way to get rid of bats from homes and attics. Glue boards, “Bat-A-Way”, or high frequency noise emitters are gimmicks and unacceptable ways to solve a bat problem. The Federal Trade Commission has provided a ban against the selling ultrasonic pest control devices.  There are no poisons, pesticides or fumigations you can use to evict bats from your home. Bats are both state and federally protected species here in Michigan. Because of White Nose Syndrome (WNS) bats are now on the endangered list. Also because of West Nile and other various diseases bats are great to control the insect population and prevent the spread of diseases. Fines for killing bats in Michigan can be up to $5,000.

Bats are a beneficial species.  They are an important part of any local ecosystem, with some species eating significant numbers of potential agricultural pests such as mosquitoes, beetles and moths. Like all wildlife in Michigan, bats can carry rabies. Human rabies cases are rare in the U.S., with an average of 2-3 cases documented each year. It is estimated that in the U.S., 40,000 people each year receive rabies post-exposure and many of these following an exposure to bats.  Some of these treatments can be avoided if the bat can be collected and tested for rabies.  If the animal tests negative for rabies, no treatment is necessary.

 When Can You Start the Bat Exclusion Process in the Fall?

Bat removal, bat control and bat relocation during the Fall months can often be the best time to exclude bats. However there are a couple things to consider. Are there baby bats? This time of year the answer most certain is no. Juvenile bats are taking flight almost every night. Is it too cold? This doesn’t typically matter for bats as long as the one way doors are left on the home long enough for the bats to leave. If there are several cold nights during the fall you should probably leave the one way doors on your home longer. In some instances you may leave them up until spring if the exclusion is done in late Autumn season.
