The Story of Matriarchal Bat Colonies...

Bats in attics are most common in summertime, starting in April. These are most often matriarchal colonies - often an extended family of sisters, aunts, grandmothers, daughters, and nieces.

One thing about bats, as far as they’re concerned: The more, the merrier!

A common scenario goes like this... It's a lovely summer evening. The sun is beginning to set. The mosquitos are coming out. The homeowners are relaxing in the back yard. And suddenly, they spot black figures or shadows like small, quick skydivers leaving their house and then returning to it.

These are no ordinary skydivers, though. These are matriarchal bats coming out of their happy attic roost to do their part in controlling the mosquito population of New Jersey.

Mommas will use an attic as a nursery because when pups are born their hair is very thin. A warm attic will act as an incubator. When mom goes out to get food in the evening and has to leave her babies, the pups (as bat babies are called) are kept warm by the heat in the attic. (If you have found a bat in the living quarters - separate from the attic - or basement of your home, it is likely you have a bachelor bat.)

There are some "positives" associated with a matriarchal colony. For one thing, they tend to be very punctual in regards to when they come in or go out, because their body's are getting ready to take care of pups and instinct takes over. This is a "pro" because it makes it much easier to plan your home's bat abatement job.

But there are also some negatives associated with the matriarchal colony.
There is a period every summer when you can’t do any kind of bat abatement on a house due to the new pups, who cannot yet fly. If you have flightless bats in the house and then separate their mothers from them with a bat exclusion, there are several possible scenarios... none of them pleasant.

A) The babies will die - and if there are enough of them you will have an
odor. Since bats tend to congregate in tight spots, you could spend just as
much money cutting open your walls to remove the babies as you have
paid for the bat abatement;  

B) Some momma bats don’t take this separation lying down and will go to
great extremes to get back in the house (i.e. your front door);

C) You could wake up in the middle of the night to see a couple of baby
bats crawling across your floor looking for momma (or worse, step on them
in the dark)!

During this nursing time, all bat abatement programs have to be put on hold. But that doesn’t mean there isn’t prep work to be done on your house so that when the babies take flight, the abatement can be completed in a timely fashion.

Abatements are safe in New Jersey up until the first week of June and then again after August 1st once the babies are flying . In general, Fischer Wildlife Control & Repairs has a policy of performing no bat valve jobs during the last two weeks of June and throughout all of July.

The Story of Bachelor Bat Colonies...

Daddy bats take no responsibility in raising their babies (called pups). The daddy bat spends all
summer hanging around drinking bat beer.

A colony of male bats is called a bachelor colony. (Any questions "why?")

When Fischer Wildlife Control & Repairs catches a bat in a house we always take the time to
determine the bat's gender. Most often during the summer months, bats that are found inside
the living quarters of your house (seperate from the attic) are male. These are also the bats that
end up in your basement.

The daddy bat has the option of roosting during the day in weather conditions that are more
comfortable than the mommy bat, who has to tend to her babies. Oft-times, if the attic is too hot,
the daddy will go into a
home's interior plumbing wall - which also provides access to the basement (where, of course, the temperature is more comfortable). This is the same wall that holds the chase-pipe, which runs out the
top of a home's roof all the way to the basement and equalizes the plumbing pressure.
