The heat is not the only nuisance this spring. Experts say that the wet weather and record amount of flooding have led to more black flies.

The little black bugs look like houseflies but have a serious bite which may draw blood. However, health professionals say the flies don't transmit diseases.

"It injects a little bit of anticoagulant, which is the same thing people take as a blood thinner. Then after they bite you, you have blood running down," said Cheryl Sampson, a school nurse specialist in Spokane, Wash.

The flies normally bite around the ears, neck and scalp leaving an itchy red bump. Sampson suggests using both Calamine lotion and Cortisone cream can help ease the itching associated with the fly bites.

The gnats are most active during the day, especially at dusk and dawn.

Pest control professionals suggest to keep them at bay, you should make sure your window and door screens are intact as well as wear long-sleeved, light clothing when you're outdoors.
