Bat Removal in Las Vegas

Frequently Asked Questions

What Are the Signs of a Bat Infestation?

The most definitive sign of a bat infestation is the presence of guano, or bat droppings, found in small, black, pellet-like piles, usually under a roosting area or near an entry point. Unlike mouse droppings, guano is dry and crumbles easily when touched. Homeowners often hear distinct, high-pitched scratching, chirping, or fluttering sounds coming from the attic or walls, primarily at dusk and dawn when bats are leaving or returning to roost. Look for brown or greasy rub marks on your home's exterior around small gaps, which are left by the oil in the bats' fur as they squeeze in and out. A strong, pungent ammonia-like odor in the attic, caused by the accumulation of urine and droppings, is also a clear indicator of a large, long-term colony. Finally, seeing multiple bats emerge from a specific crevice in your roofline or chimney just before sunset confirms their entry point.

Are Bats Protected in Nevada?

Yes, all species of bats in Nevada, belonging to the order Chiroptera, are classified as protected mammals under the Nevada Administrative Code. This protection means it is illegal to kill, trap, or harm bats, which is why humane exclusion methods are mandatory. Additionally, the federal Migratory Bird Treaty Act protects bat colonies during the summer maternity season, typically May through August, when flightless young may be present. Removal or exclusion during this protected period is prohibited to avoid trapping young bats inside the structure, where they would starve. Professional wildlife control experts are required to strictly adhere to these state and federal laws.

Can Bats Return After Removal?

Bats are highly persistent and possess a strong instinct to return to their established roost, especially if it was a maternity site. They will frequently attempt to re-enter the structure for days or even weeks after a humane exclusion is complete. However, if the exclusion process is performed correctly by a professional, the bats cannot regain entry. The entire structure must be meticulously bat-proofed, sealing every tiny gap and using durable materials that the bats cannot easily bypass. Bats will eventually give up and seek an alternative roost if the exclusion barriers are correctly installed and maintained.

What Are the Health Risks of a Bat Infestation?

The primary health risk associated with bat infestations is Histoplasmosis, a serious respiratory disease caused by inhaling spores from a fungus that grows in accumulated bat guano. Disturbing dried droppings in the attic can release these microscopic spores into the air, leading to flu-like symptoms and severe lung infection, particularly in immunocompromised individuals. Bats are also known carriers of the Rabies virus, which is transmitted through a bite or scratch, though rabid bats are rare. Furthermore, bats introduce parasites like fleas, ticks, and bat mites into the home, which can infest living areas and affect both family members and pets.

How Can I Prevent Bats From Returning?

The most effective prevention strategy is to ensure your entire home is permanently sealed after the bats have been successfully excluded. This involves "bat-proofing" all potential entry points, including sealing cracks in the foundation, installing screening over vents, and capping chimneys with appropriate material. Trim tree branches that hang over or are close to your roof, as these provide easy access points for the bats to land and seek entry. You may also install bat houses in a suitable location away from your home to offer the displaced colony an alternative, safe roosting site. Regular visual inspections of your roofline should be conducted to address new wear or damage immediately.
