Do Bat Houses Help Solve Bat Infestations?
By Brandon Stein, NJDEP-Licensed Wildlife Control Operator · 4 min read
Short answer: In most cases, no. Installing a bat house will not make an established colony leave your attic, chimney, or wall void. Bat houses are supplemental outdoor habitat, useful after a professional exclusion. Solving an active infestation means identifying entry points and excluding the colony during New Jersey's legal seasonal windows.
What Is a Bat House?
A bat house is a specially designed outdoor structure that provides bats with an alternative place to roost. These structures are often installed on poles or buildings in sunny locations and are intended to supplement natural roosting habitat.
Bat houses can support local bat populations by offering safe places to rest, particularly where natural tree cavities are limited. They also allow bats to continue providing natural insect control while staying outside of occupied buildings.
Will a Bat House Make Bats Leave My Attic?
In most cases, no.
Installing a bat house does not cause bats to voluntarily move out of an attic, chimney, or wall void. Once a colony has established a roost inside a home, it generally continues using that location until it is professionally excluded.
A bat house should be viewed as an optional supplemental habitat rather than a replacement for proper bat exclusion. In fact, the New Jersey Department of Environmental Protection notes that bat houses are intended for bats that have already been excluded from a building, helping provide an alternative roost while keeping the colony in the area.
Why Do Bats Choose Homes?
Bats look for locations that are warm, dry, protected from predators, and close to food sources.
Homes in Cherry Hill often provide ideal conditions because they may include:
- Attics that stay warm during the summer
- Small gaps around rooflines, soffits, vents, or flashing
- Mature neighborhoods with trees and nearby water sources
- Plenty of flying insects during the warmer months
Female bats often gather in maternity colonies during late spring and summer to raise their young, making attics particularly attractive seasonal roosts.
Signs You May Have Bats in Your Home
Many homeowners first notice bats indirectly rather than seeing them inside.
Common signs include:
- Bats flying from the roofline around sunset
- Small piles of bat droppings beneath roof edges or in the attic
- Chirping or rustling sounds near dusk or dawn
- Dark staining around small exterior openings
- An occasional bat entering the living space
If you notice these signs, it is important to have the property inspected to determine whether a colony is present.
Why Timing Matters in New Jersey
Bat removal is not simply a matter of sealing entry holes.
In New Jersey, bat exclusions must be performed during appropriate seasonal windows to avoid trapping flightless young inside a structure. The New Jersey Department of Environmental Protection publishes recommended safe dates for exclusions and advises against sealing active colonies outside those periods.
Because the timing depends on bat biology, homeowners should avoid attempting to block entry points on their own if bats are still using the structure.
What Homeowners Should Avoid
If you suspect bats are living in your home, avoid taking actions that could make the situation more difficult.
This includes:
- Installing a bat house with the expectation that bats will leave the attic on their own
- Sealing visible entry holes while bats are still inside
- Using repellents or poisons marketed for bats
- Handling bats or attempting to remove a colony without proper experience
Improper removal can create additional issues and may not comply with New Jersey wildlife regulations.
When to Call a Professional
Professional help is recommended if:
- You regularly see bats entering or leaving your home
- You have found bat droppings in the attic
- A bat has appeared inside your living space
- You are unsure whether the bats are roosting in your home
- You want to safely exclude bats while following New Jersey guidelines
A wildlife professional can determine whether a colony is present, identify entry points, and recommend the appropriate timing and methods for exclusion.

Bat Activity Around Cherry Hill Homes
Cherry Hill's mature trees, nearby waterways, parks, and established residential neighborhoods create excellent habitat for insect-eating bats. During the warmer months, bats are commonly seen flying at dusk throughout the area as they feed.
While bats provide important ecological benefits outdoors, they generally should not be living inside occupied homes. If they establish a colony in an attic or wall void, professional exclusion is typically the most effective long-term solution.
Do bat houses attract bats to my home?
A properly placed bat house is designed to provide an outdoor roost. There is no evidence that installing one will draw bats into your attic, but it also should not be expected to remove bats that are already living inside your home.
Should I install a bat house if I already have bats in my attic?
A bat house may be beneficial after a professional exclusion, but it is not a substitute for removing an active colony from a building.
Can bats return after exclusion?
If entry points are not properly identified and sealed after exclusion, bats may attempt to use the same structure again. A complete inspection helps reduce this risk.
Are bats protected in New Jersey?
Yes. Native bats are protected, and exclusions should follow state guidance regarding proper methods and seasonal timing.
When is the best time to have my home inspected for bats?
Any time you suspect bat activity. An inspection can determine whether bats are present and help establish the appropriate timeline for exclusion based on the season.
