What chemical is registered as a bat repellent?

Explanation:
Repellents are chemicals used to deter animals from roosting or entering an area, rather than to kill them. Naphthalene is the one that has been registered specifically as a bat deterrent, meaning it’s approved for use to discourage bats from roosting in spaces like attics or caves. The other substances are pesticides or a physical desiccant: chlorpyrifos and lindane are insecticides, not repellents, and diatomaceous earth is a physical control that damages insects but isn’t used to deter bats. When using naphthalene, follow the label and safety precautions due to its toxicity.
