Being the only flying mammal, bats are fascinating creatures. The consume up to 1,000 winged insects in just one night of heating, about equivalent to its full body weight. Bat feces, called guano, is also one of the best natural fertilizers available.
Bats often become a nuissance to homeowners because bats need heat to survive, and that makes attics the perfect place to colonize. Once a colony has moved in, it’s moved in permanently, and professional bat removal is the only way to get them out.
The first sign that a bat colony has moved in is their guano. Bats tend to defecate when leaving and returning for the night, and therefore guano can be seen around a home a bat colony has taken refuge in.
To the untrained eye, guano can easily be mistaken for mouse droppings. But, a simple test can be preformed to differentiate them. Simply roll the dropping with your finger. If it flattens and dusts out, it’s bat guano. If its hard and rolls like a rolling pin, it is a mouse dropping. Be advised, bat guano around your property is not only unsightly, but a potential health hazard. Bat guano easily breaks down into powder, and that powder can become airborne. If enough is inhaled, it can cause serious respiratory issues.
But that isn’t even the main issue that a bat colony in your attic will cause. A bat colony can range anywhere from 50-100 bats, and they all will defecate massive amount of guano and urine in your attic, and seep into the ceiling directly below, causing stains and odor in your home. The guano and urine is extremely difficult to clean up, and not just because the massive amount. As previously mentioned, breathing in guano dust can have serious health consequences, and bat urine will crystalize and form hard stalagmites which do not easily break down. Thats just one of the reason bat removal should be done by a professional.
Bat Removal and Exclusion
There are no such things as bat trap, but with professional expertise, bat removal can be accomplished through exclusion. It should be noted, exclusion work for bat removal should only be done September through April, when baby bats born in the preceding mating season are old enough to fly. Otherwise, the baby bats will be trapped and die in your attic.
First, all entry points are sealed, except for a 3 inch opening. A special bat excluder door that bats can get through going out but not in is then fitted to the 3 inch opening. It will take about a
week for the entire colony to leave. Your attic will then be reinspected, and if all bat are gone, the last 3 inch opening will be sealed. Again, it cannot be stressed enough this work must be a an experienced professional, as bats only need an opening a size of a nickel to reenter your attic if its not properly sealed off.
