Keep one of these in every blind and in the cabin. Been using them for 20+ years in deer stands. It won't keep them out totally, but it will kill them overnight. Just change them out every 3-4 months.
If you can spray around the openings, doors, windows, etc with Demon WP mixed with water in a pump up sprayer it will also kill them then later if they walk or crawl across it.
When my kids started hunting with me I started using Ortho. I spray it inside and outside. It works great. we have never had wasp of any kind in our stand.
