Despite their often-negative reputation, a bat presence is a great thing for humans. Many of the insects that bats prey on are the same ones that decimate crops and spread harmful diseases, making them a free and eco-friendly form of pest control.
However, the advantages of bat presence near a human population last only as long as the two groups don't share the same living space. A bat infestation can lead to its own diseases and property damage, making them far better neighbors than roommates.
If you live near bats but don't want a bat infestation in your home, here are three signs to look out for.
Bats are nocturnal and may hunt all through the night, but their peak periods are just after the sun sets and just before the sun rises.
Keep a lookout around your home's perimeter for thirty minutes to an hour after the sun goes down. If there's an infestation, chances are high that you'll see a large number of bats flying in the immediate vicinity.
Be on the lookout particularly for a several bats flying in the same direction away from your home, because the reverse of their flight path could lead you to the location of their roost.
Holes and Marks on Home Exterior
Like any typical mammal, bats are ultimately just looking for a safe, warm place to sleep, mate, and raise young. Unfortunately, many human homes fit the bill perfectly, and bats will not be afraid to break in by force if it means finding a safer home.
Check for holes in your home's exterior, particularly in the soffits, louvers, and roof. These areas provide the easiest access to the attic, which forms a perfect nesting ground for bats due to the high temperature and ample insulation.
While rodents like mice and squirrels can also burrow into these areas, the oil on bats' skin will leave rub marks when they enter or exit their roosts. If you find a hole in wood or siding that has dark spots around the edges, chances are you've got a bat infestation.
The surest sign that you've got a bat infestation is also the most dangerous aspect that a bat infestation holds. Bat droppings, or guano, in a home can carry numerous diseases that are harmful or even fatal to its human occupants.
Check your attic area in particular for droppings. Guano in this area a likely sign that you've got bats, and droppings in the upper parts of the house can easily get into the ventilation system and contaminate the entire home.
