Last year I noticed yellow jackets sneaking into the hive and attacking the bees. So I bought one of these to use. It caught quite a few yellow jackets and reduced the attacks on the hive.
I bought a refill kit this year and just installed it. People on amazon also recommend using apple juice in the top and peanut butter in the bottom section. I'll try that once this refill kit wears out.
3rd order of baby chicks are here!
