I am in the midst of a serious battle with the following creature: We had three of these monsters appear around our rear deck last summer. I tried to find their hive to kill them, but they appeared to live under ground in tunnels. I ended up killing them with my tennis racket and never saw any others for the rest of the year. Unfortunately this year they are back with a vengeance. So far I've probably killed close to a dozen of these, but can regularly see half a dozen or so flying about the back deck area and yard. I called a couple pest exterminators, and the first couldn't even tell me what species it was and even thought it may be some kind of giant yellow jacket. The second properly identified it as a Sphecius Speciosus AKA Cicada Killer. Here's what A&M's Entomology database had listed: So my question is - how do I get rid of these beasts??? We have a 2yr old that loves to play outside around and on the deck, but with this invasion, other than waiting until September we have been forced to keep him from that area. The pest control companies we talked to said they would not be able to rid us of the wasps due to their particular solitary underground nesting habbits. Have any of you encountered these same creatures and if so, how did you go about getting rid of them? BTW: I tried using a bright yellow bowl filled with sugar water and dish soap, as flower nectar is their main source of food, but so far I've only killed about three that way over a period of two weeks. Where as with my racket I was able to kill several in one day. My concern is that the larvae will hatch next year and the cycle wont get broken until I can figure away to get rid of the larvae. I'm almost tempted to pour concrete under the deck area!
