Bat Control and Removal
In general, bats are most active at night. Their habitat and behavior vary seasonally. Males and females typically spend the summer months apart from one another. They come together again early fall for mating. After mating, they will spend the winter in sheltered areas to include caves, mines, and attics. Bats have their young from June through July. Generally, bat young are capable of flying in August.
The types of activity associated with bat infestations can include:
- Droppings stuck to the outside of the home or dwelling.
- Bat droppings found in attics or basements.
- Small light scratching heard during the night within ceilings and walls.
Bats are associated with a few diseases that affect people. Rabies and histoplasmosis are the most serious. Rabies is a dangerous, fatal disease. However, the bat’s role in transmission has been greatly exaggerated. Though bats are confirmed carriers of the disease, only a few human fatalities have been attributed to bat bites. Nevertheless, care must be exercised when handling bats and bat bites should be considered potential rabies exposure.
*****IMPORTANT MEASURES TO BE TAKEN*****
Bats may try to bite when handled and should be picked up with heavy gloves or forceps.
If a bat has bitten someone, it should be captured without crushing its head. Refrigerate it (don’t freeze it). Take it to the local health department for testing.
Effective Control Measures:
The most common bat infestations involve attic infestations. Once properly identified, it is necessary to locate any and all possible entry points and eliminate them through repairs. The exception is to leave one entry hole unblocked where evidence of bats are apparent. This can be identified through brown smudge marks and dropping in front of the entry hole. A bat check valve is then installed at the entry point in order to release the bats from the attic and prevent them from returning. The bat check valve is typically left installed for approximately 10 days depending on the weather patterns.
