Bats can enter the house through a number of locations.
There are cases when bats thrive in a house for weeks or months
without being detected, until their droppings soon get accumulate and
begin to attract your attention. To check if bats really live in your
home, try to visit the attic and see if there are rub marks and other
signs of droppings. Locate the entry points and openings bats use during
the warmer months, then look out for bats leaving your home as dusk
arrives. They usually go out half-hour before until half-hour after
sundown. Once you have confirmed their entry points, you can proceed
with sealing all the openings, cracks and crevices bats go through. You
may use various materials for sealing, such as hardware cloth, sheet
metal, caulking, wood, fly screen, expandable polyurethane foam, or
fiberglass.
You can seal the entry points by:
- Covering the openings one night when all the bats are out of the
house. It is not recommended however to do this task during the
months of June and July as these are the months when bats give birth
to their young.
- Hang a piece of bird netting and seal it from above the openings
with duct tape or staples. Let the bottom opening as is. This method
lets the bats get out of the house but prevents them from entering
the dwelling. Once all the bats have been removed, all the openings
can be sealed.
- Seal the openings anytime between November 15 and March 15. This
is the ideal time to do the proofing as bats are already out to
enjoy their hibernating time.
- Seek for wildlife and other animal experts who can help you
remove the bats as you need someone who has the experience in
handling bats.
