I have made use of a few home-remedies (sort of) to treat the plants, and my cat! First, turned some dried Rosemary into powder in the coffee grinder and rubbed it in my cat's fur. It's supposed to deter fleas. (He didn't have hardly any to begin with).
Then this morning I mixed up several five-gallon bucket's worth batches of hot pepper spray to treat the garden plants, which are already getting devastated by cucumber beetles and japanese beetles both. The Pumpkins and Green Beans in particular are starting to look sick. My sprayer bottle conked out and wouldn't spray anymore so I just threw the pepper water over the plants until they were dripping. Mixed three kinds of hot sauce and a dash of dish soap into the water, is all. It was strong enough that the scent of it off the plants when I was done made me cough! I treated the pumpkins, green bean poles, chard (still not sure what's eating that), cherry tomatoes and the sole cantaloupe plant. Nothing's eaten the cantaloupe leaves yet but if the bugs get driven off the bean poles I don't want them to start attacking my cantaloupes.
I've also been simply drowning the offending bugs, but simply can't keep up with them.
