Bat Removal And Control MN

There are seven species of bats that are native to Minnesota: the Little Brown, Keen’s Little Brown, the Big Brown, Pipistrelle, Silver-haired, Red, and Hoary. All of these species are insect eating. They are between 3-6 inches long, have a wingspan of between 9-15 inches, and weigh between 0.2 to 1.1 ounces. The Hoary bat is the largest found in Minnesota, and the Pipistrelle is the smallest. The Little Brown bat is the most common species in the summer. The Big and Little Brown bats are colonial species (they live in groups) and are the ones most often found residing in bat houses. During the summer bats have their pups; usually one or two during June or July. Since Minnesota can get very cold in the winter, most bats will migrate south to warmer climates or hibernate until the weather is warm again. Read the rest of this entry »


Bat Removal Minneapolis MN

The Minnesota bat problem is just as prevalent as other states. This though can lead to a small Minnesota bat problem becoming a large Minnesota bat problem because people are unsure what the problem is. In the state of MN there are only seven MN bat control species that live there.  Only two will live in dwelling, little brown myotis and the large brown bat. Read the rest of this entry »

Fast Spreading Fungus Threatening Useful Bats

One of the most common bat species could face extinction in the Northeast of the U.S. within decades due to white-nose syndrome, a disease now rapidly spreading.

‘White-nose syndrome’ disease spreads in Northeastern U.S.

While bats may have a bad reputation, frightening many people, they are vital in controlling insects that not only annoy but also spread disease to people and animals. Read the rest of this entry »

Minnesota Bat Removal and Disposal

Minnesota has seven species of bats. Two of the most common, the big brown bat and the little brown bat, will commonly roost in people’s houses. Bats do much more good than harm eating tons of insects, including mosquitoes, each year. But when they move in with people they can cause problems. Of greatest concern is the potential for diseases such as histoplasmosis found in bat droppings and the rare occurrence of rabies in a bat that might fall sick and be found by a pet or child.

Bats In Your House?

September 22, 2010

Bats are truly wonders of nature.  They represent the only flying mammals (flying squirrels glide but cannot fly).  The sonic, directional, object detection ability not only serves them well while flying, but it was studied as a part of various research projects during the development of radar and sonar.  Bat species in Minnesota are primarily insectivores.

Bats breed but once a year and depending on the species, females deliver one or two pups.  By early August the young are flying along with the adults, but, until then, they are confined to the roost while the adult females fly in and out to hunt and feed their young.  Males live separately from females until the fall migration when the sexes mingle and spend the winter together at their hibernation sites.

Only two species of bats the Big Brown Bat (Eptesicus fuscus) and the Little Brown Bat (Myotis lucifugus) are any threat to man.  Individuals from these species will enter houses in the spring and fall.  During the spring where attic and eve temperatures hover between 90 and 103 degrees F, female little brown bats can use the areas as nurseries for raising their young.  Big brown bats prefer slightly cooler locations for their nurseries.  Also big brown bats can tolerate much colder winter temperatures and are active later into the fall than are the little browns.  Both species, however, require fairly constant temperature and humidity during the hibernation period. Little browns are likely to hibernate in caves where the temperatures stay above freezing.  Big brown often successfully hibernate in attics, eve areas, abandoned bird houses, etc. where temperatures may fall to below 0 degrees F.

Both species of bats can enter very small openings.  Any circular opening the diameter of a nickel will allow their passage.  It is more common for them to enter buildings via more accessible routes such as broken attic windows, unprotected roof/gable vents, along side exterior masonry chimneys, sprung corners on eves, where dormers meet the main roof, etc.

If your house is currently under attack by bats it is wise to call a professional.  It is very important that proper inspection techniques and execusion methods be utilized.  If not, you could end up with numerous adult and/or young bats being closed in your walls, eves, or attic, causing a large sanitation problem from dead bats or even having bats come out into your house with you and your family.


Bats Are Beneficial…We Just Don’t Want Them In Our House

In February 2006 some 40 miles west of Albany, N.Y., a caver photographed hibernating bats with an unusual white substance on their muzzles.  He noticed several dead bats.  The following winter, New York Department of Environmental Conservation biologists documented what they called white nose syndrome after seeing bats behaving erratically, bats with white noses and a few hundred dead bats in several caves.  More than a million hibernating bats have died since then, making WNS the worst wildlife health crises in memory.

Since 2006, more than a million bats have died from a disease called White Nose Syndrome.  Biologists don’t know what causes it, nor do they have a cure, and so far, it’s proven to be almost 100 percent fatal in bats that contract it.

There are seven species of bats in Minnesota, four of those hibernate in caves, two will live in dwellings.  Little brown Myotis and the large brown bat, and could potentially be at risk.

The little brown myotis is known to consume up to 100% of its body weight in insects each night.  This level of insect consumption provides an important ecosystem service to human kind, and to the balance of natural and human-altered ecosystems, which in turn can reduce the use of pesticides often used by humans to kill insect pests.

You may not like the little critters, but if you notice bats in your home, or suspect you have a bat infestation, call a wild animal management professional today.

Bat Exclusion

Bats find their homes in walls and attics of homes, churches, barns and other buildings year-round, maternity colonies also in hollow trees.

Bats are nocturnal and are active only on warm dry nights.  They come out approximately 30 minutes after sunset, feed until they are full, roost the rest of the night, then return to daytime roost before sunrise.

MN has 7 different species of bats.  They are the Little Brown Bat, Eastern Pipistrelle, Northern Myotis, Big Brown Bat, Red Bat, Silver-haired Bat, and Hoary Bat.

The most common bat to enter buildings is the Big Brown Bat and Little Brown Bat.

Buildings where bats have resided for years can suffer incredible damage from the guano and urine left behind.   Readers are cautioned that bat cleanup requires special equipment as it can pose incredible safety hazards.

Having bats in your home is a serious problem, even if they are confined to the attic.  Not only do they urinate and defecate anywhere they roost, causing staining and odor problems which are difficult to remove, they are associated with dozens of diseases which are dangerous to humans, including histoplasmosis (a lung disease caused by the spores of fungus which grow on their droppings or guano) and rabies.

While bats are very beneficial to humans because of their affinity for many flying insects, such as mosquitoes, if they find their way into your home and take up residence, they can also be some of the most destructive, dangerous and expensive pests to control.

Since bats are a protected species, removal must be done by a trained professional.   In addition, we can perform repairs to your home or business so they cannot re-enter.

Meet The Brown Bat

The most common bats that we deal with here in Minnesota area the Little Brown Bat (Myotis lucifugus) and the Big Brown Bat (Eptesicus fuscus).  The Little Brown has a wingspan of about 7 inches.   The Big Brown has a wingspan of about 12 inches.  Both look similar, with velvety brown bodies and darker faces.  Both are insectivorous.  They roost during the day, oftentimes in colonies inside buildings, and emerge at dusk to drink water and feed on insects.

These bats can eat almost half of their body weight in insects per night.  They primarily consume beetles and moths.  The young are born in the summer, usually in June.  They are born large and grow quickly, and are able to fly within about 7-8 weeks.  These bats usually form what are called maternity colonies – large groups of female bats that roost together and raise their young together.  These maternity colonies can be as small as 30 members, or as many as several thousand, space permitting.  They mate in the autumn, but delay fertilization until spring. Depending on the conditions in the roost, the bats may migrate elsewhere in winter in order to hibernate, or they may stay put.  Bats are in the order Chioptera, meaning hand-wing, and are of course flying mammals.

If you have a bat infestation in your house, your best bet for getting rid of bats that you can’t seem to control is to call a professional in to do the job for you. Pest management professionals–know what they’re doing and they’ll get the job done right.  The only surefire way to get rid of a bad bat problem is to trap the bats and safely release them a good distance from your home–a very good distance. So, go ahead and call your local pest control professionals and get an estimate done.  Hiring a professional company guarantees the safety of you and your loved ones, along with prevention services to keep bats out for good.

Getting Rid Of Bats

The Big Brown Bat is a common bat involved in nuisance wildlife removal, because like the Little Brown Bat, it’s a colonizing mammal that likes to live in buildings.  It looks fairly similar to the Little Brown Bat, except it’s …bigger.  It has a wingspan of maybe 10 inches and it weighs 5/8 oz, which while small, is quite a bit larger than your average colonizing bat.

The colony sizes are generally smaller than those of other species.  A colony might consist of ten to twenty members, whereas the Little Browns or Freetails can form colonies of thousands of members.

Regardless of colony size, the behavior is the same.  They form maternity colonies of females, they give birth to young in the summer, they leave their roost at night to catch insects on the wing, and sleep during the day.  They are controlled via exclusion methods – one-way removal devices that let them fly out but not fly back in.  They are valuable creatures that should not be killed.

We specialize in nuisance wildlife control – this is the field of removing unwanted wildlife from homes and property, and solving conflicts between people and wild animals.  From home inspections to preventative repairs, wildlife trapping, attic cleanups and more, we solve critter problems with professional expertise.

If you are dealing with a bat infestation, call your local pest control professionals and get an estimate done.  Hiring a professional company guarantees the safety of you and your loved ones, along with prevention services to keep bats out for good.

Signs Of Bat Infestation

Bats play crucial ecosystem roles, the most prominent being as predators of insects.  They are also some of the most common carriers of rabies, and the handling of them should be avoided.  There are seven species of bats native to Minnesota.  Here we will only be listing the two most common bats; the big brown bat and the little brown myotis.

Big Brown Bat – Eptesicus fuscus

Description: The big brown bat has a total length around 115mm (103-145), with a tail around 42mm (38-47), making it Minnesota’s second largest bat. Its fur is uniformly brown, and the wing and tail membranes are black.
Status: The big brown bat is the most common large bat in Minnesota, although less common than the little brown myotis. It ranges from southern Canada into Central America and the Caribbean.
Natural Role: The big brown bat primarily feeds on beetles, but will feed on other insects when abundant. They are preyed upon by snakes, raccoons, cats, and various birds of prey.
Agricultural Role: This is primarily a beneficial species to agriculture, feeding on many agricultural insect pests, including the corn root worm, “perhaps the single most important agricultural pest in the United States” (Mulheisen and Berry, 2000).

Little Brown Myotis – Myotis lucifugus

Description: The total length of the little brown myotis is around 91mm (83-99), with a tail around 38mm (32-48). Its fur is a coppery brown above and buffy gray below. It has a dark spot on each shoulder, and the ears are fairly short.
Status: The little brown myotis is one of Minnesota’s most common bats, and it ranges throughout most of North America.
Natural Role: This bat feeds primarily on moths, although it will eat a variety of other insects.
Agricultural Role: The little brown myotis is primarily a beneficial species to agriculture, feeding on many insect species that are considered pests.

All of Minnesota bats feed on insects such as beetles, moths, flies, and mosquitoes, etc. Bats mate in fall and winter, giving birth to young in April through July.  Young bats grow very vast and can fly within three weeks.

Signs of bat infestation in your home:

  • Squeaking, scratching, or crawling sounds in your walls or attic
  • Dead bats found in your home
  • Bat droppings inside of house, in the attic, or walls, etc.
  • Seeing bats fly away from your home at dusk
  • Strong urine smell, especially on hot days

People are most likely to encounter nuisance bats when a roosting colony takes up residence in a building.  Attics often make excellent habitat, as do barns.  Bats need only a half inch or less of space to crawl through in order to enter a building.  Once inside, if the habitat is good, the colony grows until the homeowner notices the bats flying out of the building, notices the droppings in the attic, chimney, outside, or even basement.  Sometimes a bat will get lost and find its way out of the attic and into the living area.

Getting rid of bats requires experience.  If your house is currently under attack by bats it is wise to call a professional.   Permanent exclusion is the best way to remove bats.  First, all entry points must be located and repaired.  Professional bat removal ensures that the colony will no longer use your home or business as a roosting area, and that no bats can get back in.
