I have a rather serious flea beetle infestation. Small seedlings are being
stripped before they can get big enough to survive the damage. I hesitate to
use chemicals that say things like "wait 3 weeks after using this before
harvest". Garlic spray doesn't work. Wood ashes doesn't work. Does anyone
have any practical advice on how to handle flea beetles without getting out
pesticides that kills everything that lives? I'll do that if I have to, but
I'm open to safer alternatives.
