Exterminators typically do not kill bats but instead use exclusion methods to remove them from your attic. Since bats play a vital role in controlling insect populations, and it can be illegal to harm them, professionals use repellents, install one-way devices, and seal entry points to stop them from returning.
Bat remediation often takes two to four days but may take up to a week, depending on the size of the infestation. During colder months, when they hibernate, remediation can take far longer. Most removal pros don’t do exclusion during this time because bats are in a state of torpor and may be sealed inside the structure.
To keep bats out of your house, seal any openings larger than ¼-inch. You can also use bright exterior lighting or ultrasonic devices to discourage them from coming near your home. Have a bat exclusion expert check your home periodically for infestations and provide tips on keeping these pests away.
Some of the top bat deterrents include mothballs, electronic or ultrasonic devices, devices with flashing or strobing lights, and chemical repellents that contain naphthalene. Electronic audio and light deterrents claim to confuse and repel flying creatures. It’s best to rely on your bat removal professional to place and maintain any deterrents or chemicals.
Homeowners' insurance does not cover bat removal costs because these expenses fall under home maintenance. In rare cases, a policy may contribute toward guano removal or repair of damages. Review your insurance policy carefully and contact your provider for a definitive explanation. Securing all entry points remains the homeowner’s responsibility to prevent future incursions.
