So I constantly have wasp problems here. They seem to be all over the place and sometimes get into my trailer. Now that the first freeze is approaching and they are probably gone for the year, I came across this neat, quick, wasp trap. (Thanks Roku) I'll have to try it next year. Mine is going inside my house though, not outside because I don't care if the wasps are out there. They do serve a purpose in controlling the populations of other insect chains like caterpillars, and the like.
Anyhow, pictured below is the little trap that I made. You take a water bottle and cut the top part off, remove the lid and invert it. It fits nice and snug. Then you can decorate it or not. You put the bait (something sweet) inside the bottle and wait. It really works too. I saw how many were in the bottle on the demonstration.
