DALLAS - A Texas exterminator thinks he mnight have an explanation for recent bedbug infestations.

Alex Contaboni with Safe Pro Pest Control investigates hundreds of homes every year.

"I will go to million dollar homes that have cleaning people or nannies, and they're immaculate."

The exterminator, coming over to take care of an unwanted infestation.

"They're like, 'I'm not dirty, I'm not dirty, I swear'."

People who do not have pets find themselves with fleas.

"And a big problem nowadays is bedbugs as well."

Yes, even bedbugs in homes where no one has recently taken a vacation or gone on a business trip.

"They bring vacuums from customer to customer."

Now, Contaboni believes has has solved the mystery.

"As the maid is cleaning the rest of the house, maybe something jumped on there and you didn't notice it, and she puts it in the bucket and takes it to the next house."

He believes cleaning services are cross-contaminating homes, from vacuuming up roach, flea, and bedbug eggs in one home and unknowingly bringing them into another.

"And as they're vacuuming, they're vacuuming up the eggs of the fleas. Well, fleas spread through the eggs."

B&B Maid Service makes sure it changes out its rags, brooms and mops before entering a home, if the clients don't want him to use their own cleaning gear and supplies.

"We provide new and clean rags for every cleaning."

Contaboni recommends anyone entering your house use protective shoe covers as well.
