If you are looking for a bat removal company you have come to the right place. Bats are winged mammals that are in the order Chiroptera. They are very beneficial animals despite many needs for bat control. This usually is due to feces or guano accumulation from infestations. These organisms in the attic cannot be relocated during their maternity season. A single of them can consume 1000 insects an hour so humane critter control should always be done if controlling them is your goal. A trap is never recommended as it is illegal to hire bat exterminator services, which are usually offered by pest control companies. They cannot be killed. At Triangle Wildlife Removal we do not kill or exterminate them. They are active at night during the spring, summer, and fall. Around central North Carolina such as Chapel Hill, and Durham, they will be active in the winter on mild or warm evenings but will quickly retreat to hibernation during extreme cold. Many people put up houses in order to keep them near their properties in hopes to avoid animal extermination. The most common species in the Triangle area are big browns, little browns, and Brazilian free-tailed. These flying mammals are normally found in houses in gable vents, between chimneys and flashing and behind shutters. The sight of droppings is usually a key indicator that you’ll need a professional along with cleanup for their droppings. They are frequently found in older concrete and brick commercial buildings high around the roofline where settling has occurred. The normal signs that are seen are rub marks at entry points, rustling and chirping in voids, large accumulations of droppings (guano) and the odors and organisms associated with the colonies.

The beginning of May through the end of July marks the time frame when female bats are raising their young – called pups. Commission biologists urge homeowners to avoid closing up holes or installing eviction devices during this time, as young bats, like other mammals, depend on their mother for survival during the first few weeks of life.

“If a homeowner installs an eviction device or covers up the holes that bats have used to get into the house, female bats may not be able to get to their young after a night of feeding, and the young bats would starve to death,” said Jessie Birckhead, the Commission’s wildlife extension biologist. “If any bats are sealed inside, including pups that can’t fly, they will search for a way out and may find their way into the homeowner’s living space.” – North Carolina Wildlife Resources Commission

Bat Exclusion

All bats have state and federal protection, even infestations that have caused a nuisance bat emergency. The females comprise the maternal colonies. They will typically have one set of twins during the end of May through the month of June. At this time, a transfer is prohibited by the North Carolina Wildlife Resources Commission. The “blackout period” for maternity season is from May 1 through July 31 for the entire state. The juvenile ones, both little browns and big browns, are volant in about three weeks (flying). The exclusion can then be started for control. They are not trapped but excluded from a roost. They are easy to transfer but the difficulty is sealing all entrances, which is also called animal exclusion, larger than 3/8″ on the structure. They are very persistent and will search all available penetrations around a roof area for a new entry. These entries can usually be found by grease marks or feces. Gable vents, soffits and gaps are the most common areas when dealing with these infestations.

Houses may need to be caulked in the following places:

• Between window drip caps (tops of windows) and siding
• Between door drip caps and siding
• At joints between window frames and siding
• At joints between door frames and siding
• Between window sills and siding
• At corners formed by siding
• At sills where wood structure meets the foundation
• Outside water faucets, or other special breaks in the outside house surface
• Where pipes and wires penetrate the ceiling below an unheated attic
• Between porches and the main body of the house
• Where chimney or masonry meets siding
• Where storm windows meet the window frame
• Where the wall meets the eve at the gable ends the attic
• Where wall meet the eves anywhere on the structure. Source
