Do not bother exterminators who do not specialize in bats, use ridiculous inhumane trap "methods", scare tactics, or chemicals that are simply a waste of time.

The only proven way to deal with bat/human conflicts is a systematic repair of all sides of your structure. Suggestions such as extermination (illegal in most states), trap and release, chemical repellents, floodlights, and cheap ultrasonic devices are half hearted attempts at best, and at worst some may actually be dangerous to pets and family. These "methods" do not address the problem at the root: bat entry crevices must be repaired. Otherwise bats just simply keep coming back.

Bat control is non-lethal and relies upon exclusion and sometimes installing bat houses to provide alternative places for bats to live and still provide free insect control nearby. Bats are not physically captured. This is sometimes difficult, hazardous work that requires experience with bat behavior, specialized equipment, and a high degree of safety precautions.

Site Survey

• We inspect the exterior and/or the interior of the structure noting bat exits. This service can be done year-round.
• An estimate is given for the bat exclusionary are happy to explain procedures, materials, and timing. Any other possible solutions are discussed and weighed (e.g. increased ventilation, total roof/soffit replacement).
• We will help you select a site for a bat house which is both suitable for bats and homeowners.
• A written report with sketches and/or photographs is prepared on request.
• We can survey the structure during the summer exit flight if needed, noting entrances and counting the actual number of bats involved.
• In the end, many people are able to take all this information and couple it with work already being planned or simply do it themselves Site surveys range from $50-$150.

Structure Repair

• Timing is important. If your bats are migratory and you live in northern latitudes or at high elevation, October-March is fair game for an all around sealing attempt. In most southern states a more elaborate approach involving bat "escape hatches" is appropriate and usually requires several trips and a degree of patience. This work is also seasonal to avoid entrapping flightless young within the building.
• The cost of the bat exclusion varies from site to site, depending on the amount of work to be done, the size of the structure, and the site accessibility. Residential structure repairs can range start at $800 but never exceed $3,000.
• If bats are still using your structure the summer after our sealing because of failed repairs, we will revisit and repair the structure at no labor cost. A basic travel expense may still be assessed, usually up to $300.
• Extra large complex structures (multiple dormers, towers, bump outs, etc.) or traditionally bat-friendly roof types (slate, tin, Spanish tile, or wood) may require a larger than average level of effort.
• An active bat exclusion (a sealing attempt when bats are present) may temporarily increase the chances of encountering a bat within the living spaces.
• We use adhesive caulking, never messy, nasty spray foam for a professional, clean job.
• We will expect to use relatively lightweight, narrow, and 4WD lift machines almost exclusively on your project. In this way we are able to spend our time inspecting work rather than dealing with cumbersome ladders and scaffolding.
• Because of the nature of the work, some work may be performed after dark to ensure progress.

Bat House Installation

• We will help you select a site for a bat house which is both suitable for bats and homeowners.
• If desired, we then install a premium Bat House providing all necessary materials (post, pole mount, assembled box, concrete, etc.)
• Site surveys and installations start at $300 including one Bat House on a post. Additional quantities at cost on the same visit.
• A note about bat houses: providing alternate habitat for your displaced colony is an ideal way to keep bats nearby and maintaining the free insect control homeowners already enjoy. Bats will be more likely to favor the new artificial roost nearby over your now difficult to access structure. This reduces the chance of bats becoming imperiled when they must seek other roost structures in the community whose owners may use hazardous or inhumane methods to deal with them. However, simply installing many bat houses does not guarantee any success unless the original structure is successfully repaired.

Recently the PA Game Commission clearly made it illegal for any contractor in Pennsylvania to kill bats. A number of other state wildlife agencies have similar policies, so please be wary of any individual who proposes this "solution" or prepares to seal bats within a building without any allowance for escape.
