As the snow melts, your roof thaws, the flowers bloom, and the bugs fly, out come the bats. Bat removal, bat control and bat relocation during the Spring months is a time sensitive matter. You want to make sure your exclusion and repairs are done before the juvenile bat pups are born. Maternal mothers will start to have their pups sometime during the second or third week of May. During your bat inspection our technicians can determine if you have a maternal colony of bats with born pups. It may even be determined that you have a bachelor male colony of bats which separate from the maternal mothers during the Spring months.
Questions we often hear during the Spring months in Michigan:
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 Spring or any month for that matter is through a live bat exclusion.
Bat Removal Process in the Spring Without Detail is a 3 step process:
- Inspection: Locating entry points and other potential entry points.
- Live Bat Exclusion: Installing one way doors and bat proofing the rest of the home.
- 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 spring months, getting rid of bats usually takes between one and two 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 fumigation 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.
Bat removal, bat control and bat relocation during the Spring months can often be a great time to exclude bats. However there are a couple things to consider. Are there baby bats? The old saying goes “June and July let them fly” Meaning, do not block the mothers out of their nursery. A typical Spring cutoff time is the last week in May.
It’s possible, but not likely. Most bats in your home come from the attic or fireplace. On occasion the bats may enter by leaving a door or window open, but that typically means there is a colony near by.
Most importantly you have to be patient. Bats living in your attic over the summer will leave if excluded by a professional. It should only take a few months for the bats to leave your home. Bats that enter your home during this time may be very disoriented and are simply looking for a way out. If you find a bat flying in your house open a window or door. The bat may fly out within a few short minutes. If you can not get rid of the bat from your house, it may be time to call a professional.
Not all attics need to be clean out, but many do. The winter or colder months are the best times to clean out the attic. During the hot summers, it is nearly impossible to perform the whole clean-up. The attics are simply too hot. However we can fog them with a mold treatment with our portable atomizer. During your home inspection we will look in the attic and determine if you need attic restoration work.
