Saw a YouTube video yesterday from the UF Beekeeping Extension Program suggesting the use of beneficial nematodes as a way to prevent hive beetle infestation. Those little buggers are the Bain of my hives (wax moths too) especially with the heat this time of year... Anyone had any experience/success with this? If not, any suggestions (beetle jails aren't cutting it--my bees seal up the entrances with propolis!)?:s
