5 Signs of a Bat Problem
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.
Bat droppings also know as guano, 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.
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 or Squeaking
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.
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.
