How small of a hole can a bat get through? Most often bats find their way into homes through cracks and crevices in building materials. Their small size makes it easy for bats to tuck themselves into even the smallest of gaps. They can squeeze through holes as small as 6 millimetres or about the size of a dime.
Why are bats important? By eating insects, bats save U.S. agriculture billions of dollars per year in pest control. Some studies have estimated that service to be worth over $3.7 billion per year, and possibly as much as $53 billion. This value does not, however, take into account the volume of insects eaten by bats in forest ecosystems. U.S. Department of the Interior
Bats become a nuisance when they roost in large numbers in human dwellings. The rapid accumulation of guano (bat droppings) is unsanitary, and serves as a fertile breeding ground for a fungal disease called Histoplasmosis, which is transferable to humans who breathe in the fungal spores.
How long does a bat live? Between 20 and 40 years. Compared to a similar-sized animal like a rat that lives only two or three years, bats live between 20 and 40 years. Researchers theorize this has to do with the ability of bats to fly.
Why is bat poop toxic? Histoplasmosis is a disease associated with the droppings of bats known as guano. The disease primarily affects the lungs and can be life threatening, particularly to those with a weakened immune system. It is transmitted when a person inhales spores from fungus that grow on bird and bat droppings.
Can you die from bat poop? Both humans and animals can be affected. The disease is transmitted to humans by airborne fungus spores from soil contaminated by pigeon and starling droppings (as well as from the droppings of other birds and bats). On occasion, the disease can cause high fever, blood abnormalities, pneumonia and even death. Health Hazards Associated Bat Droppings
How do you find a bat hiding in your house? Bats will most likely land somewhere they can hang—behind curtains or upholstered furniture, on hanging clothes, or in house plants. Carefully place a plastic tub or similar container over them. Gently work a piece of cardboard or stiff paper under the container, trapping the bat inside. Humane Society
