With summer winding down, bed bugs are picking up. It's peak season for them since many are traveling.

"When people go away to hotels or anywhere, you can get them from anywhere," said Robert Gaul, the technical director for Thomas Pest Services. "Cars, vehicles, buses, trains, any area you can get bed bugs. They'll attach themselves to luggage, shoes, clothing."

Thomas says it has 25% more bed bug clients than this time last year. Even though you can see bed bugs with the naked eye, many people go months without realizing they have an infestation.

Bed bug bites will usually be three in a row, and on specific parts of the body like the arm or the leg.

To get rid of them, pest control services will heat the home to at least 120 degrees and use chemical treatments, but Gaul says to avoid major problems, when you get somewhere, check for bed bugs.

"Definitely inspect the area that you're sleeping or sitting on," he said. "Be careful of your luggage and where you're putting it down. As soon as you get home, inspect your luggage. Take everything, all your clothes and everything that you have that you brought with you, put it in the washer on hot water and dry it on high heat."
