Bat Removal & Exclusion in Elmira, NY

Bats in your Elmira home

The bat in the Elmira attic is, in the overwhelming majority of attics, the big brown bat — a sturdy, mouse-sized hunter that spends its nights skimming the Chemung for insects and its days asleep in the warm dark under your roof. The valley's tall wood-frame houses are generous with roost entries: gable vents whose screens have perished, gaps behind chimney flashing, separations under ridge caps, spaces behind shutters. A bat needs an opening you could slide a pencil through, and a house built before the Civil War's grandchildren has hundreds of candidates.

The method, always, is one-way exclusion and nothing else — no exterminating, no chemicals, no shortcuts — and the craft is in the calendar. Through early and mid summer a colony is raising pups that cannot fly, and sealing exits then would entomb them. From fall into early spring the colony hibernates, sometimes in the very attic it summered in. Between those seasons sits autumn: every youngster on the wing, the colony still traveling nightly, winter not yet begun. If you are reading this in October, you are reading it in the window.

October in the valley: why the timing is the service

A fall exclusion succeeds because it asks the bats to do something they were about to do anyway — move. With the summer's pups flying and feeding on their own, a one-way valve on the exit costs the colony nothing: they leave at dusk, hunt the river, and settle in a tree or another roost when the door declines to readmit them. Try the same job in deep winter and you are disturbing animals in hibernation, burning the fat that stands between them and April. Try it with newborns in the attic and the arithmetic is grimmer. The inspection, the dusk exit count and the valve work are skills; knowing which fortnight they belong to is the profession.

Two bats that are never part of a routine job

New York is home to two bats protected as endangered by both the state and the federal government — the Indiana bat and the northern long-eared bat — and both live in this region's wider landscape. They favor trees and caves over houses, so an attic colony is a big brown colony until proven otherwise, but proof is the operative word. Identification precedes exclusion on every job, and if a roost ever pointed to a listed species, the valves stay in the truck: those animals are left strictly alone and the matter goes to the DEC, whose direction governs anything that happens next. There is no version of bat work in which a rare bat is treated as a scheduling inconvenience.

Mapping a tall house for a very small problem

Elmira's older homes stand two and three stories, with stacked porches, dormers and additions accreted over a century — which means the bat survey happens on ladders and at dusk, not from the sidewalk. Droppings beneath an entry and faint staining at a vent tell us where to watch; the watch itself, as the colony pours out at sunset, tells us where the valve belongs. Then the unglamorous bulk of the job: sealing the score of other gaps — flashing, ridge, vents, trim seams — that a returning bat would otherwise try next. Excluding bats from one hole of an open house is how colonies end up in the wall instead of the attic.

Droppings, dust and the bedroom bat

Guano is the colony's archive, accumulating under the roost beam season after season, and it is handled with respect — never dry-swept into the air of the house, cleaned with protection, and removed where it has saturated material. Separately, and more urgently: a bat loose in the living space is a call, not a catch-it-yourself moment. Bats are one of New York's three rabies-vector species, so a bat found in a room with a sleeping person, a small child or a pet means the room gets closed, the bat stays untouched, and you check with your physician or the county health department about exposure — with our crew handling the animal itself.

The valve week, night by night

With every side gap sealed, our crew fits the one-way valve at the colony's proven exit. Night one, the bats leave through it as usual. What changes is the return: the valve opens outward only, and the colony spends the small hours investigating a building that has politely stopped admitting them. Over several nights they relocate to natural roosts — they are wild animals with options, and upstate valleys are full of hollow trees. Exit watches verify the attic has emptied; only then does the valve come down and the final gap get sealed in lasting material. The bats lose an attic. They keep everything else.

Discovered them in June, or in January? Read this first

A June discovery usually means pups on the premises, and the correct response is an inspection now and a firm booking for the fall exclusion — the colony mapped, the entry list written, the wait explained. A January discovery likely means a hibernating colony, and the correct response is to leave it asleep and plan the spring work. Homeowners sometimes feel that 'wait' is a non-answer; in bat work it is frequently the only lawful and humane answer there is, and the inspection that accompanies it is what makes the eventual exclusion a one-visit success instead of a season of attempts.
