A Not So Nice Beetle Looking Video
Sorry this is not one of the best video. When it is Japanese beetle season right here once more, I will attempt to get a greater one.
That is the kind of bucket I wish to use–it’s huge for enormous beetle looking success and has so many different nice makes use of too.
Hprevious the bucket below the place beetles are munching (or mating), and slap the leaf or department to ship the beetles “swimming” for a bit earlier than they die.
BEETLE DEATH CHANT: If you happen to say “I’ve bought you, you disgusting bugs!” simply previous to the assault, it positively helps.

DEAD BEETLE TIP
Do NOT–I repeat, “do NOT” depart the open bucket wherever close to your problematic beetle space. Some folks say that useless beetles do not entice and can even repel different beetles, however I’ve discovered it to be fairly the alternative.
