Over the past 20 years, we have responded to more than 15,300 calls about yellowjackets.  Yellowjacket nest control is an important part of public health vector control because reactions to stings can sometimes be life-threatening. And unlike bees, they can sting more than once and can also bite.

We are excited to be hosting an Open House!  We will have kid-friendly activities, insect displays, information about rats and yellowjackets, displays of our equipment, and light snacks. The Open House will be held on Saturday, August 12th, from noon to 4pm.  Learn more HERE.  We look forward to seeing you!

Please check around your yard and home for any containers holding water - dump out standing water to prevent mosquito breeding. Check crawlspaces for standing water - water under a house can breed thousands of mosquitoes.
