While there are thousands of species of bats around the world, the Little Brown Bat is the most common species found found in Northern Michigan. The Little Brown bat is a small to medium sized bat with an average life expectancy of 2 years. Bats are the only mammal that can truly fly. They are nocturnal and hibernate during the colder winter months. The Little Brown Bat typically gives birth to one pup between May and July. They are typically found in homes and buildings, and can live in colonies up to 500. They forage for insects at about 10-20 feet over trees and lawns and can often be seen sweeping low over water to drink.

Bats can enter a structure through an pencil-size opening, or through an open door or window. Primary entry locations include attic vents, facia boards, soffit corners and chimneys. Entry points may also be found above gutters, roof vents, exterior high hat lights, and ridge caps. Entry points are most commonly identified by droppings and/or rub marks on the structure. A preliminary bat inspection is required to identify current and potential bat entry points from the exterior that lead into the interior of the structure, prior to performing any exclusion, eviction, and/or venting. A preliminary inspection may also reveal evidence of structural defects or contamination within the structure.

Bats can carry rabies and transmission to humans may be possible if any physical contact has been made. Clients should always take every precaution to avoid direct contact with bats and should contact a professional at the first available opportunity if they know or believe physical contact has been made. Bat droppings, or bat guano, may also be hazardous to humans through exposure to histoplasmosis. Health risk is based on the amount the amount and location of bat guano, and if any disturbance of bat guano has been made.

Bat exclusion is the process of sealing, caulking, screening, and/or venting all potential bat entry points on the exterior of the structure found at time of inspection to evict the bats and prevent future entry. Bat removal is often done through the use of one-way exit devices that allow bats to leave the structure but not re-enter. Bat trapping is not a biologically sound method of eviction and is not used or promoted by Hogarth’s Pest Control.

Big Brown Bat

The Big Brown Bat can be found southern-lower Michigan and can live for more than 20 years. Big Brown Bats are often called a winged and flying mouse. Their mating season starts in fall but females do not give birth to the pups until May-June. They usually give birth to two pups per litter. From May to September female bats will roost in attics, belfries, barns, behind shutters, in trees, and can be found in both urban and rural areas. Big Brown Bats are often found overwintering on the inside of attics, and like to maintain an environmental temperature of around 100 degrees fahrenheit. Big Brown Bats are nocturnal mammals but will occasionally fly during the day. We get calls about bats getting inside the house in the living space and we will come out and net them if possible to find best to get them into a contained area. All it takes for a bat to enter into a structure is about a dime size hole ¼ inch and cannot naw or chew. There are a few types of bat calls we first is the place that you know has them living in the structures, second kind a random bat or two flying around exterior looking to get in or hanging out, and finally the single bat that makes his way into the living area inside of structures.

Little Brown Bat

The Little Brown Bat is the bat most commonly found in Northern Michigan and has a lifespan of up to 25 years. Similar to the the Big Brown Bat, mating season takes place in the fall and winter and females retain the sperm until they give birth to the pups in May-June. Little Brown Bats typically only have one pup per year and have a 60 day gestation period. The Little brown is very similar to the big brown just the body size there wingspan variety a bit.
