The dates are not guidance and they do not bend. From 1 May through 31 July, bat evictions and exclusions are prohibited statewide, except under special circumstances approved by the North Carolina Wildlife Resources Commission. So if you find bats in the attic in June, the answer to when can they be removed is August. Anyone offering to seal them out next week is offering to break a rule and to kill the animals in your roof.
Why the window exists
It is pup-rearing season, and young bats cannot fly. Seal the exits while they are in the roost and the adults are shut out while the pups are shut in, which means dead animals in the structure, odor, and a mess inside a wall or ceiling that costs far more to put right than waiting would have. The prohibition exists to prevent exactly that.
Bats are protected here
Bats are a protected species in North Carolina, so this is not a matter of personal preference about wildlife. The work is regulated, and the licensed operators who carry it out are called Wildlife Control Agents, with the Wildlife Resources Commission publishing a list of them. If you are calling around, that is the term to use and the credential to ask about.
What legitimate work happens inside the window
More than people expect. Inspection to confirm it is bats rather than squirrels or rats, identifying the entry points from outside, mapping the roost, and planning the exclusion so the crew can move the moment the window closes. Guano volume and location can be assessed and an honest scope can be written.
Interior protection is the other half. Sealing the route from the attic into the living space, closing gaps around attic hatches, ceiling fixtures and duct penetrations, keeps the animals out of bedrooms while they remain in the attic lawfully. Full exclusion follows from 1 August.
How to tell it is bats
Chittering or scratching in the small hours rather than in the middle of the day. A sharp ammonia odor building through the summer. Small dark droppings that crumble to shiny fragments and collect in a heap below one spot rather than scattered along a run. Greasy staining around a gap in the fascia, at a gable vent, or where a roof line meets a wall. Squirrels are noisy at dawn and dusk and chew; rats leave droppings along their routes rather than in one pile.
Why this is not a weekend project
Not because it is difficult, but because both obvious moves are wrong. Sealing the gap traps animals inside, which is the whole reason for the closed season. Climbing into the attic to shoo them out puts you in contact with wildlife and disturbed guano, and if contact with a bat does occur, that is a conversation with a doctor rather than something to sleep on.
Repellents, ultrasonic gadgets and mothballs do not move a colony. What moves a colony is a one-way exclusion device on every entry point, installed at the right time of year, followed by proper sealing once the roost is empty.
What happens after 1 August
Exclusion devices go on the entries so bats can leave and cannot return, they stay in place long enough for the roost to clear, then every gap is sealed with materials that hold up on a roof line. Cleanup and sanitizing of the affected area follows, and insulation sometimes has to come out. That is the point where the job stops being a wildlife problem and becomes a building repair, so get the sealing scope in writing rather than as a verbal promise.
If it is June and you have bats
Book the inspection now instead of in August, because everyone else in the county with the same problem will be calling on the first of the month. Get the entry points identified, get the interior sealed off from the attic, get a written scope for the exclusion, and put the work in the diary for the first week the window is open. Attics around Spring Lake and in the older parts of town with open gable vents are the usual candidates.
