Little Brown Bat Control: Protect Your Home


What Do Little Brown Bats Look Like?
Size: A typical little brown bat measures around 2 to 4 inches in length and typically weighs around half an ounce. The wingspan of the small creature typically ranges from 9 to 11 inches.

Color: As suggested by their common name, little brown bats are covered in brown fur. Their wings, face, and ears are black.

Characteristics: Little brown bats have small, mouse-like ears and hand-like wings. Their flying patterns are erratic, mostly due to food-catching behaviors.

  • Species: Little brown bats are common to North America and belong to the mouse-eared bat family.
  • Problems: Bats are a source of fear for many people, which possibly stems from the fact that they transmit disease. However, since they keep insectivorous diets, little brown bats are actually beneficial to have around.
  • Population: Unfortunately, in recent years, the future of the species has been compromised by white nose syndrome, an illness responsible for decimating around 95 percent of the eastern little brown bat population.


What Do Little Brown Bats Eat?
Little brown bats are primarily insectivores and eat a considerable portion of their body weight each night, which is the reason the animals are considered natural pesticides.

Nursing females will often consume more than 100 percent of their body weight in one night of feeding.


Life Cycle
The life cycle of little brown bats is somewhat abnormal for mammals. These creatures mate during the fall and sometimes in the winter during hibernation.

The females eventually wake in spring and form nursery colonies consisting of up to 1,000 bats ready to care for the coming offspring.

Newborn pups cling to mothers until the young bats are too large to be carried. The offspring are ready to explore the world and gather food on their own within three to four weeks.


  • Flying: Look for little brown bats flying during the day.
  • Roosts: Keep an eye out for roosts, especially beneath roof overhangs, house eves, and inside attics.
  • Feces: May notice collections of excrement in areas where the bats rest.

Problems Caused by Little Brown Bats

As a widely accepted symbol for horror and spooky themes, bats are also unwelcome for their unsightly appearances, which evoke discomfort.

Health Risks
More importantly, though, bat infestations heighten the possibility of disease transfer. The accumulation of bat droppings can be deadly if ingested or inhaled.

While little brown bats are known carriers of rabies, just a small percentage of individuals are actually infected. However, any bite or scratch should be treated immediately.

Signs of Infestation

  • Activity: In contrast to popular thought, not all bats are nocturnal. Little brown bats are active both during the day and evening hours, so spotting an adult during daylight could indicate an infestation.
  • Sounds: While the echolocation sounds bats use are too high-pitched for the human ear, people can hear the various squeaks bats make, which may also indicate a nearby little brown bat population.

Prevention Tips

As is the case with any unwelcome pests, sealing off points of entry to buildings is the first step in prevention.

Additional measures include:

  • Building adequate bat housing away from private property to encourage the animals to steer clear of homes.
  • Limiting food supply is nearly impossible as insects are abundant and resist prevention methods.

Tips for Removal from Home

Wild animals should never be handled without professional training.

When removing little brown bat infestations, it is essential to also rid areas of dropping and urine accumulations.

Call the Professionals
Cleanup requires careful sanitation techniques and proper disposal methods. Therefore, eradication should be done by professional pest removal teams.
