Summer Creek High School in northeast Houston is yet another school in our area dealing with a bat problem.

This year's bat season has already been busy, considering it really doesn't get going until March.

"Yeah, its been pretty active," said Tim Hanks, a bat-proofing specialist and owner of Commercial Bat Control.

Southeast Texas lies in the middle of the migration path of the Mexican free-tailed bat, and as they are heading back some are finding refuge in local schools.

"Your auditoriums, your gymnasiums are usually the tallest buildings in some small towns so bats will get in those," said Hanks.

A bat was spotted at Summer Creek High School in late January.

"All the bat needs is a thickness of a pencil and an inch long to get in," said Hanks.

Over the weekend, the school district took action by sealing up the building's cracks and installing excluders -- a device that allows bats out, but not back in.

"Our school district has a contract in place with a pest management specialist who are knowledgeable about this because this is something we want to proactively deal with," said Jamie Mount, the director of public information for Humble ISD.

On Wednesday, four more bats were discovered on campus, but the district said they have no reports of students coming in contact with the animals.

Humble ISD sent out an email telling parents about the bat problem and included safety guidelines like never touching a bat.

The bat activity will continue to increase as bat season typically goes from March to late November, but it started early this year because of a warm start to February.

We will see a boom in the bat population this summer, not because they are still migrating into the area but because the babies are born in July and August.

There are benefits to having bats around. They feed on insects five to 10 times more than birds, which in turn helps control the mosquito population.
