SHERMAN, TX -- They don't buzz, they don't bite, and although they're small, they can be a bigtime annoyance.

"There are several families that include things called gnats, gnats are typically small flies of less than 5 millimeters in body length," said Dr. Steven Goldsmith, Austin College faculty member.

They can be found in large swarms most often in the summer months. But this year, they're here early.

Experts blame the early arrival on the unseasonably warm winter we had.

"The changes that we're seeing in the weather patterns are changing the nature of biological diversity here in North Texas," said Goldsmith.

Gnats love fungus, which thrives on moisture, so you'll often find them around potted plants, fruit, and even trash cans.

"The best way to get rid of gnats, fruit flies, you've have to find the source of where they're coming from," said Charles Nunley, All Star Pest Control owner.

You can use natural products, pesticides or even call an exterminator to try and eliminate the pests from your home.

But they say you may just have to put up with them...since there's no way to get rid of them completely.
