What Are Brown Bats?

Brown bats are the most common bat found in Massachusetts and can be separated into two types: little brown bats and big brown bats. The two are incredibly similar in appearance, but as you might expect, big brown bats are typically larger, measuring up to five inches in length while little brown bats measure just below four inches long. Both can be recognized for their light brown fur, black wings, and large ears.

Brown bats tend to roost in caves in the wild but are often found in attics, roofs, and even hiding in wall voids. They primarily feed on insects like mosquitoes, beetles, flies, and even wasps. In some respects, brown bats can be useful in maintaining the ecological balance, eating up pest insects that would otherwise overrun the area. Their droppings, or guano, are a potent fertilizer and can help local plants to grow.

Why Are Brown Bats Dangerous?

Brown bats are dangerous because of the many pathogens they transmit. As new science emerges, bats are quickly outpacing rodents as the most dangerous hosts of zoonotic viruses — that is, a virus that is transmitted from an animal to a human being. From SARS to Marburg virus, there’s no shortage of severe illnesses that bats can cause.

While brown bats don’t deliberately hunt or hurt people, they will certainly bite if cornered or handled. Bats are known vectors of rabies, and if you are bitten by a brown bat, you should seek medical attention as soon as possible. Bat droppings can also be hazardous and exposure to large amounts can lead to histoplasmosis, a fungal disease that attacks the respiratory system.

What Attracts Brown Bats?

Water, food, and shelter are the main factors that attract brown bats. A yard with lots of flowers and standing water provides bats and their prey with everything they need. When brown bats choose a place to roost, they prefer somewhere dark and secluded and may return year after year, so unattended outbuildings like sheds and barns are particularly vulnerable to brown bat infestations. 

Some simple ways to deter bats from your property include: 

  • Controlling prey insects – Trim hedges and mow the lawn often to reduce hiding spots for the bugs that brown bats eat. Consider reducing the number of flowering plants on your property like honeysuckle and raspberry, as they attract insects.

  • Reducing water access – Ensure that drains and gutters are flowing properly and no water is backed up where bats can get a drink. Dump any standing water in buckets, pots, or other containers around the property.

  • Preventing entry – Examine your property for any holes or openings that bats could use to enter. Fill smaller holes with silicone caulk or patch with metal mesh. Always use chimney caps, window screens, and draft guards to keep pests out.

When brown bats decide to nest on your Merrimac property, they can be nearly impossible to get rid of without professional intervention.
