Chiggers by Wizzie Brown

What Exactly Are Chiggers? Chiggers are the first stage out of the egg of a particular type of mite. They climb onto people and other animals walking through infested areas, crawl upwards, and wander around the body seeking a good site to settle down and feed. Feeding preference for these mites on humans is in areas where skin is thinnest (behind knees, armpits) or where clothing fits tightly, such as the ankles, waist, and the groin area. What Causes All That Itching? Chiggers do not burrow into skin… Read More →

Cicada Killer Wasps by Wizzie Brown

What are these giant wasps?!?!?!?!

Forest Tent Caterpillars by Wizzie Brown

Tent Caterpillars Start to Appear in April Forest tent caterpillars cause damage in the larval, or caterpillar, stage.

Other tent caterpillars make a web between two branches… Read More →

Ants and Termite Swarmers ID by Wizzie Brown

Watch for Flying Objects Soon it will be time for swarming insects to emerge out from their homes in the ground and fly into the air in search of a mate. Usually, this event coincides with warm temperatures and a significant rainfall event but can also occur if you forget to turn off your irrigation system. “Swarmer” or “alate” are other terms that describe the reproductive stage of ants and termites. These insects have wings when they initially leave the colony, but the wings are either shed or… Read More →
