Bats

Bats play a vital role in the ecosystem, consuming thousands of insects — including mosquitoes — each night and contributing to pollination and seed dispersal. But when they take up residence in a home or building, they bring health risks and structural challenges with them.

Are Bats Dangerous?

Bats are generally harmless to humans, but they can carry rabies and spread histoplasmosis, a respiratory illness caused by fungal spores in bat droppings. It's crucial to avoid direct contact and seek professional help when bats are present in your home.

Signs of a bat infestation:

  • Squeaking noises — high-pitched sounds from walls, attics, or chimneys.
  • Guano — accumulation of bat droppings, resembling dark, crumbly pellets.
  • Stains or odors — yellowish stains and a strong ammonia smell caused by urine.

Where Bats Roost on Your Property

Bats roost in caves, hollow trees, and man-made structures — attics, barns, and chimneys among them. During winter, some hibernate in protected spots while others migrate. Tap a spot below to see the risk.

Tap any glowing spot to see the roosting risk there and what to do.

Bats are the only mammals capable of sustained flight, and they use echolocation to navigate and hunt in complete darkness. That said, if you're seeing signs of a bat infestation — squeaking in the walls or attic, guano, or ammonia-like odors — avoid direct contact and seek professional help.
