My petunias are being devoured by something. I think it is some little worm. I saw one on there the other day and knocked it off. I've also noticed little tiny green bugs on them. Anyhow, I sprayed them down with a combination of water and dish soap. I hope it doesn't kill them. Does anybody know of an effective way to get rid of these pests besides pesticides?
Diotomaceous earth (I'm sure I've spelled that wrong) is natural and kills quite a few things. I'm not sure what you've got. DE is a powder--you can get a cheap puffer spray can at the hardware store to apply it. If you can identify the bugs, you can always buy live, natural predator bugs to destroy them.
You really should get a magnifying glass, a glass jar with a lid and go out and collect a couple of the pests, then to online and identify them. Then you'll have a better chance of getting rid of them.
