Bats are often classified as a pest species because of their habits of living in homes. The most common complaints include the following; Bats living in the attic, bats living in the chimney, odor because of bat droppings, bats swarming around building, loose bat stuck inside home. For all these reasons, lots of folks desire to have colonies of bats removed from the building. Please bear in mind that this is a specialty service.
Step 1: Perform a complete inspection of the construction. This is to determine precisely how the bats are getting in and out. Step 2: Perform a attic review, and learn how to recognize the species of bat. This is essential since different bats have different birthing and hibernating seasons. Read here why you shouldn't try and perform bat trapping, but instead bat exclusion, that's the practice of allowing them fly out, but not back in, to the construction.Step 4: Seal up the home to keep bats out indefinitely. In actuality, much of this is done ahead of the exclusion - just make sure not to seal up the key exit points while some bats are indoors!! Step 5: Clean the attic or walls, or area where the bats lived and defecated.
BAT BIOLOGY: North America is home to many species of bats, but these are the three most frequent nuisance (colonizing) species in the US: First is the Little Brown Bat (Myotis lucifugus) that's normal in most of the US, particularly the northward states. The females form large maternity colonies, often in structures such as attics or barns. The Big Brown Bat (Eptesicus fuscus) is also common in the northern regions. They partner in October, before winter hibernation, and after a delayed fertilization and a 60 day gestation, give birth to one or two infant bats in early June. The Mexican Free-Tail Bat (Tadarida brasiliensis) is common in the southwest. These bats will form massive colonies up to several million members in some instances. They mate in the autumn, but delay fertilization, and one pup is born in early June, and can fly about eight months later. All these bats often roost in buildings that are man-made, and love the attics of houses. None of these animals are in fact blind, but they do use echolocation so as to help in navigation on the wing. They're all insectivorous, catching insects on the wing.
When it is a colony of bats living in a building, they creep to the edge, and fly out. They go for water and get a drink, skimming the surface on the wing. Then they feast on flying insects, primarily moths and beetles. After some time they get complete and return to the roost to be able to rest. Then they fly out to feed more. Bats use echolocation so as to assist in navigation and feeding on the wing. They exude high-pitched chirps and read the sonar-like yields of the sound waves as they bounce back from objects. Roosting preference is dependent upon the species and even sex of the bats, but we're just concerned with colonizing bats like the three mentioned above. The men roost alone in solitary locations, like trees. The females form tremendous clusters, very often in man-made architecture like church towers, attics, bridges, etc.. They tolerate and even favor very high temperatures. Lots of the southern bats migrate to different areas as climates change. But, bats in the north hibernate in colder weather.
NUISANCE CONCERNS: the principal concern involves large colonies. When it's just a couple bats, it might not be a big thing. But if you have got a normal maternity colony of bats in your house or building, it can be a huge issue. A huge colony isn't just noisy and unsettling at dusk and dawn as swarms of bats fly in and out, but the primary issue is they leave their droppings and urine behind. With a huge colony of bats, this really adds up. After some time big piles of droppings form. Not only do the droppings and urine corrode wood/metal, but the weight of them are able to collapse the ceiling below the attic - I have seen if a couple of times. The waste has a foul odor, but it may also grow fungal spores which individuals can breathe in, resulting in the lung disorder Histoplasmosis.
BAT DISEASES: I have already discussed Histoplasmosis, a fungal disease of the lungs which results from the spores that grows on nitrogen-rich bat droppings, but it's also important to remember the fact that most the cases of rabies transmission in the United States have come from bats. This might be because people are less cautious around bats than say, rabid raccoons, or since bats are tiny and can bite and infect people in their sleep. Or maybe the specific strain of rabies that bats or specific species of bats take is more likely to infect people. Regardless, if you find a sick bat on the floor, do not pick this up, since you may get bitten!
Bat removal isn't an easy task. There's absolutely no effective bat repellents that could do the job easily. The proper way to eliminate them would be to exclude the colony - seal off 100 percent of potential secondary entrance points on the house and eliminate all the bats from the building safely. It's often very challenging, and it has to be done just the perfect way. An amateur effort, by somebody with no experience, or worse, a pest control company that uses bat toxin , could lead to tragedy - dead, rotting bats, and bats swarming through the walls and the house. The way to eliminate bats in a construction - install one exclusion removal devices on the principal bat entrance and exit holes to the home or building, and also clean the mess afterward.
There's not any registered or efficient bat repellent available. Some companies will try to sell anything - there is a good deal of so-called bat-repellent or bat-away goods on the marketplace, but they're bogus. The FTC has issued a warning against these - ultrasonic sound emitters don't work. There's not any easy and quick fix when it comes to bat management. It's ideal to get a professional with years of experience deal with the issue.
