Can I remove bats from my attic myself?
Indiana DNR guidance generally allows an individual to remove up to five bats within a 24-hour period from a dwelling without a permit, where the bat is a demonstrable but non-immediate threat. Beyond that, a permit or an operator is needed.
The guidance asks that removal be humane, and that any bat taken be reported through DNR's sick-or-dead-wildlife tool. Contact with bats should be kept to a minimum, and nobody should touch one with bare hands.
For a colony, or for any circumstance outside that guidance, a permit or a contract with a wildlife control operator is the route. DNR's Living with Wildlife page is the place to check the current rules, and the technician will explain which of them apply to the building.
When is the right time of year to evict bats?
DNR recommends eviction in spring or autumn, which helps avoid trapping young bats inside the building. The technician plans the job around that guidance.
A colony sealed inside a building cannot leave, which is why the timing is set with care. The right window is not a date on the calendar. It depends on the season and on what the technician sees in the roost.
This page gives no maternity-season months, because the sources reviewed did not confirm them for Indiana. The technician checks the roost and the season before any device is fitted.
What moves the price of bat exclusion?
Roost size, the number of exits, the height of the roofline and whether repairs are needed all shape the job. The technician confirms the price on site, and it is explained and approved before any work starts.
A small attic with two or three gaps is a shorter job than a barn loft with several exits high on the gable. Repair of damaged trim, soffits or siding after the bats are out adds to the work, and so does a second visit to check the devices.
Bat work is specialized and not every operator does it, which can affect the plan. No figure appears on this page, and the technician explains the scope before anything starts.
Why do bats come back after I seal the gaps?
Bats return when a gap is left open or a new one appears. Sealing before the roost is empty can trap them inside, so the order of steps matters.
A missed opening, a gap sealed too early or a second entry on another side of the building can all keep a roost active. A technician checks the building from the outside at dusk, before and after the work, for this reason.
Bats can return to a roost they have used before, and a sealed opening can still be found by a bat looking for shelter. Keeping the trim and the eaves in good repair is the long-term fix.
How do I know the bats are gone?
Watch for a few weeks for droppings, sounds and bats coming out at dusk. A quiet roost after a full check is the sign the job has worked.
The technician usually asks the homeowner to report any new droppings or sounds in the weeks after the work. Bats that remain may still be roosting on the outside of the building or in a gap that was missed, so the follow-up matters.
If a bat is found inside the living space or on the floor, do not handle it. Describe where it was found and call the technician, who will explain what to do under DNR guidance.
