Many people don't realize that the larva of this bug damages the roots of many plants. I had an issue with these beetles and then found my spinach was wilting and no longer attached to the soil. It was only then that I found out the larva was the Southern Corn Rootworm. So when somebody says plant a trap crop I say get rid of them, they will damage more then you can imagine.

If you see a cuke leaf with sudden wilting or dry patches, look under there for one of these beetles.

Our kids call them "man bugs" and we don't call them anything nice! They've ravaged our green beans, zinnias, squash, cucumbers, melons, day lillies, iris, roses and more. This year is worse than last if that's possible. We've now replanted the first 5 above and are at wit's end-down to nubs again! Our large garden supplies fresh organic vegies to folks that can't garden. We don't want to kill all the good bugs. HELP!

This nasty critter has started to grab hold in our yellow and green bean plantings in western Penna. We will start treatment in a day or so. Thanks to other posters for suggestions.

These bugs suck the life out of my roses and I've been fighting them for 3 years. I don't want to use things that are toxic to all insects but I am frustrated with them. They destroy the flowers while they are young buds so the blooms are malformed and black around the edges. They are very destructive.

I live in the Bay Area of California. I finally had it with these bugs this year when they ravaged my dahlias. I got nematodes from the local nursery and applied as directed. A couple of weeks passed and the numbers dwindled significantly. With that and some early morning/late afternoon finger murdering, I've managed to eradicate the pests. I would highly recommend this treatment to anyone. Also, praying mantis will eat these beetles but they will also eat beneficial ladybugs.

The spotted cucumber beetle is very damaging to my roses, and most other flowers at this time of year (late July). I now find out that they are also the culprits for transmitting the bacterial wilt disease ravaging my garden. Bad bug! Insecticidal soap seems to be helping somewhat. They were legions last week and, following treatment, they are reduced to regiments. I live in an agricultural area and the more they spray the crops, the more the bad bugs come into the small gardens. So my insecticidal soap has probably only caused my poor neighbors to be attacked more heavily. I thought it was interesting that a "major horticultural publication," in just this month's issue, had the range of the Diabrotica as Florida to Texas in the south and New York to Minnesota in the north.
