If you are using a bee-vac for wasps of any type just take a piece of 1/4" hardware cloth and build a little cage over the intake piece of the vacuum (inside the shop-vac or bee-vac). This will destroy them as they go into the container of whatever you prefer.
The Wasp Warrior In A Kilt The college art student we hired last summer loved the whole idea of David Mcleod
"warrior" removing bees & wasps in a kilt.Don't try this at home without a bee suit. Kilt optional.
You want to run them through a very blunt screened object at a very extreme high rate of speed. Warrior talks about his development of his wasp killing vacs and how he reverse engineeered Rob Overton's gentle Bee hive removal System .
The best visual image I can give anyone is you want to end up with dead wasp exoskeletons in pieces on the other end. The last thing you want to do is pizz off yellow jackets and not kill them.Warrior told me wasp removal is something he fell right into. People do not know the difference between a Bee and Wasp and if you pre sell a bee removal job 80 miles away you need to get paid for the removal wasp , bee or otherwise. Warrior had himself a full hive in one of Rob Overton's bee vacuum systems. It took Warrior getting stuck with live wasps into developing a out of the box, ready to use wasp killing system . Anyways at some point warrior will chime in if you don't catch the podcast.
When warrior first described it to me it reminded me of "MR BONE STRIPPER" on a 1991 Movie Comedy Classic "Nothing But Trouble" With John Candy, Chevy Chase, Dan Ackroyd and Demi Moore. If you watch the movie you will get the idea of how a
wasp killing system should really work.
