Protect Your Home While Keeping Connecticut’s Bats Safe Seeing a bat near your house is one thing. Realizing bats may be living in the attic, behind the fascia, or somewhere inside the roofline is another. Bats have an important place in Connecticut’s environment, but the inside of your home is not where they belong. At Suburban Wildlife Solutions, I do not treat bat exclusion as a matter of chasing a few bats away and hoping they stay gone. I first need to know where they are entering, how they are using the structure, and whether the time of year allows the work to move forward safely. That information shapes the exclusion plan. The aim is to separate the colony from the building, close the routes it has been using, and protect the home without ignoring Connecticut wildlife rules or the bats’ natural behavior.
Bat exclusion calls for patience. It also calls for someone who will inspect more than the opening you happened to notice. I look at the building as a whole because bats may use several gaps around the same roofline. The visible exit may be the main route, or it may be one of several. Closing only that spot can push the colony toward another opening that was missed.
My recommendations come from the evidence at the property. I first examine what should occur when considering the season, structure, activity of the colony, and the conditions of materials around the entry points before giving an explanation about what will happen next.
Bats search for warm temperatures, protection from predators, and a quiet day-resting location. A house can provide all three. The opening may be tiny. A gap beneath flashing, a loose ridge vent, a narrow space along a soffit, or a joint beside the chimney can be enough. Dormers, fascia boards, and ordinary construction seams can also give bats a way into the structure. Once a roost works, bats may return. Some colonies use the same building year after year because the temperature, access, and shelter continue to suit them. That is why finding one opening is not the end of the inspection. I need to understand why the building worked as a roost in the first place.

Bat exclusion is different from handling many other nuisance animals. The goal is not to trap a colony inside the building or relocate bats one at a time. One-way devices allow bats to leave on their own while blocking the route back inside. Once the colony has left, the remaining holes may be closed, and the nest site will no longer serve as a roost. Sealing too early can trap bats inside. Removing one device while leaving another gap open can shift the activity to a different part of the roof. A proper exclusion accounts for the colony’s exit routes and the other openings it may test afterward. The result should protect the building without harming the bats.

Female bats can form maternity colonies in late spring or early summer and give birth in warm attics or roof openings. The young cannot fly at first. If the adults leave to feed and the building is sealed behind them, those young bats may remain trapped inside. That creates a worse problem. Before exclusion begins, I consider the season, the activity around the building, and the possibility that young bats are present. Species identification can also affect the recommendation when it is possible to make one. The bats’ life cycle determines the timing. The calendar cannot be ignored.
Bats may be observed flying out the door from one corner of the roof at night by a homeowner. That helps me to begin, but it doesn’t tell me all. I walk through the rest of the building. I search for openings around vents, roof intersections, fascia, chimney joints, gaps around flashing, gaps around dormers, and the search for openings around flashing. Route marks of dark staining or rub marks may indicate a route that has been ridden many times.The setting matters too. Bats may settle in different areas around the house depending on the trees in the vicinity, the shape of the roof, surrounding habitat, and how air circulates through the upper portion of the house. Often, it’s the little things that tell the story.
I worked with Suburban Wildlife Solutions for a number of years before establishing the company, and studied wildlife ecology for many years at Southern Connecticut State University as I pursued my Master’s degree. My graduate studies focused on animal behavior, habitat selection, and animal responses to suburbanization. That experience changed how I inspect buildings. I don’t assume that 2 bat issues are the same since the houses appear alike on the street. The situation could change with roof design, repairs, surrounding habitat, age of materials, and the time of year. I inspect first. Then I explain what I found and recommend an exclusion plan based on the structure, the season, and the bats using it.
Bats leaving the roofline at dusk are an obvious sign. Guano beneath an opening, sounds above the ceiling, or staining near a vent may point to the same problem. Do not seal the first gap you see.
Suburban Wildlife Solutions offers Bat Exclusion services throughout Connecticut. I check the building, locate the paths that bats are using, and inform you of what must be done to safely exclude the colony.
No. Exclusion timing depends on whether a maternity colony and flightless young are present. An inspection helps determine when the colony can leave without trapping bats inside.
They may test the structure again. When the colony has exited and the primary and secondary openings are properly sealed, the building becomes much harder for bats to reuse.
Yes. Bat work should follow Connecticut and federal wildlife guidance, including rules related to protected species, maternity periods, humane handling, and the timing of exclusion.
Small openings around flashing, rooflines, ridge vents, soffits and fascia, around chimneys, dormers, and around construction joints where openings may occur as the building ages.
Do not seal the opening or disturb the colony. An inspection can identify the routes being used and determine whether exclusion can move forward safely.
