Bat Safety in NH and Maine
While bats are beneficial (they help control insects like mosquitoes, pollinate plants, and spread fruit seeds), they are referred to as pests for a reason when they find ways into the home. They can also be associated with health risks such as:
- Rabies — the most common disease associated with bats. Rabies is typically transmitted through a bat bite and can be passed to animals and people. It can make victims very sick and, if left untreated, can be fatal.
- Histoplasmosis — a disease that generally attacks the lungs and is caused by bat dung (guano) left behind in large amounts where bats roost. Bat droppings can harbor fungus; infection in humans can occur when people inhale spores. Bat urine can also create strong odors. We often find droppings that lead to staining in ceilings and walls and provide cleanup services to sanitize affected areas. Colonies in your attic can leave droppings that may become a hazardous situation.
- Parasites — bats can also leave behind parasites such as bat bugs, which resemble bedbugs and can infiltrate your home.
Because bat droppings (guano) can be hazardous, and because bats are common carriers of the rabies virus, property owners and property managers are strongly advised not to attempt to remove bat infestations or clean guano accumulations on their own.

How to Remove Bats
The most effective and humane bat removal process from a building technique is through exclusion. This is our way of assuring bats leave the home safely. Bat exclusion means that we locate any openings bats are currently using to gain access into the building and install one-way doors on those openings, enabling the bats to leave the building and move back into the wild, but not return to your residence.
Upon installation of the one-way door, technicians will identify and seal all possible re-entry points (the bats may look for another way in and only need an opening about the size of a dime).
Most of the time, one-way doors are left on until the next scheduled removal window unless you require sooner. We do like to leave on for a few weeks to assure everyone is moved out. Depending on the season, bats should be gone within 24-48 hours, unless they are hibernating in winter months.
When technicians return, they reinspect the property, remove the one-way doors and seal the opening or openings to prevent future bat entry into your home.
Coexisting with nature is always our goal. However, if they are in your home, many people prefer not to exist at that level. If you are concerned about a bat problem, contact us for humane bat removal and cleanup services today.
Bat Removal FAQs
How do you remove bats from a home?
Bat removal is done through a process called exclusion. We install one-way devices over entry points that allow bats to exit safely but prevent them from getting back inside. Once all bats have left, we seal the structure to prevent future entry.
Is bat removal safe and humane?
Yes. Professional bat removal is designed to be completely humane and follows state and federal regulations. Bats are not harmed during the process—they are simply excluded from the structure and allowed to relocate naturally.
When is the best time to remove bats?
The best time for bat removal is typically late summer through early spring. During the maternity season (usually May through August), removal may be restricted because baby bats are unable to fly and would be left behind.
How do I know if I have bats in my attic?
Common signs include scratching or squeaking noises at dusk or dawn, staining around rooflines or vents, and the presence of bat droppings (guano). You may also see bats exiting the home at sunset.
Will bats come back after removal?
Not if the job is done properly. Professional exclusion includes sealing all potential entry points, which prevents bats from returning. Without proper sealing, bats are very likely to come back.
