American Bat Removal bat specialists are experienced in recognizing bat colonies and are thoroughly trained to ensure the best solution is initiated when handling these problems that require residential bat removal. Bats are extremely territorial and unless the proper steps are taken to remove them correctly, the problem will persist and probably increase over time. Residential bat removal should only be done by licensed, qualified professionals.
Common Residential Bat Hideouts
- Tile roofs. Most bats live underneath tiled roofs. Barrel tiles or “Spanish Style,” are the preferred type of tiles to form colonies under. Bats roost underneath the tiles which lay on top of the plywood decking. Contrary to popular belief, bats do not roost in the attic space with this type of roof. They congregate under the tiles finding an opening which may be as small as ¼ inch wide. Once under the tiles bats can spread out taking up as much room as needed to accommodate the colony. Most bats prefer lighter colored tiles in the summer and darker colored tiles in the winter.
- Cedar shake roofs. Cedar shake is another type of roof which bats often roost in. Unlike the barrel-tile roofs, bats can only roost under the ridge caps. Ridge tiles overlap and sit on top of each other, forming a tunnel that is a premiere place for bats to establish a colony. Entrance to the ridge caps can be found anywhere up and down the entire length of the ridge. Often times there can be several entrances, so locating the bats is important to avoid trapping bats in the roost. The remedy to this type of roof is performing a safe and harmless residential bat removal process where needed, and sealing off all of the ridge caps to prevent the bats from moving into another section of the roof.
- Ashpalt shingle roofs. Unlike the barrel tile and the cedar shake tile, asphalt shingle tiles are glued to one another so it is impossible for the bats to crawl underneath them. On asphalt shingle roofs, bats are most likely to roost behind gapping fascia boards or in gaps or holes in the soffit area of the roof. In this case bats would have access to the attic. Most bats will stay in close range to their entrance and exit hole, and seldom wander around the attic freely. Once the residential bat removal is complete and because of the potential health hazard posed from the feces and urine, new insulation should be replaced.
- Metal time roofs. Metal tin roofs are much like the cedar shake roofs. Bats usually roost under the ridge caps and occasionally bats may find a gap where roof sections may overlap such as in dormers and crickets. Metal roofs tend to heat up faster than tiles so bats may favor this type of roof around the colder time of year to keep them warm during the winter months. To secure a metal roof from future bat infestations, all the ridges need to be sealed after residential bat removal has been performed on the affected areas.

- Staining: A brown or grey stain where bats are entering and exiting the roost. This is the area were exclusion nets are placed. Stains are oil based and can be difficult to remove. Bleach products and grease removers work well on the stains.
- Guano: Bat droppings underneath the roost site. The droppings are pellet like in appearance. Droppings may also stick to walls and windows. With time, the droppings will turn to dust and flush away with a good rain shower or strong wind.
- Smell: A musk like urine smell from the bats themselves and not the droppings. Most of the smell will dissipate once the bats are gone. Insulation in attics should be replaced to further eliminate the offensive odor.
- Chirping: Bats have a social roost chatter that sounds much like baby birds chirping. This chatter is audible to the human ear and is used mainly for communication amongst the colony itself or as a warning to let other bats know of impending danger
- Visual Confirmation: Look for bats leaving the roost in the evening just around sunset or returning to the roost just before sunrise. Estimate about double the amount of bats if you count them. Not all of them will leave the roost every night. Weather may also play a factor on the size of the emergence.
