You are right, many types of wasps will eat insect larvae. Wasps are good in the garden. Sounds like you have eggs from cabbage moths. Yes, the larvae/worms/caterpillars, whatever you want to call them, will do damage to your cabbages.

That's cabbage worm poop, not eggs. The holes in the leaves are from the worms. If you have a few plants you can hand pick and squish the worms. I use an organic spray with the active ingredient spinosad.

Hi Teresa. Robin's right! Maureen

Yeah, it doesn't look like eggs to me. At first glance it looked like slug poop, which it might be. Or Cabbage Worm poop. In any case, you should closely and intimately visually inspect your cabbages to find out what's in there. Cabbage worms can be effectively controlled on a small scale by hand picking. Although they are very well camouflaged and hard to spot.

I'll second everyone: cabbage worm poop. The paperwasp is your friend. Last year, I ended up very sick and stopped handpicking my broccoli, cole crops. When I finally made it out to the garden, I was overrun with cabbageworms. Dejected, I went back to the house (still sick) and decided to try handpicking again in a few days. Three days later, I couldn't find a single cabbageworm. The paperwasps had moved in and collected every one. This year, I have not had to hand pick at all. So far, the wasps have completely kept up with the cabbageworms. My kale remains beautiful and hole free. So, protect your wasps! Don't knock down their nests and don't use pesticides. I also wouldn't worry about them stinging you. I've been in the middle of them for two years and they've never, ever gotten nasty with me. There's an old saying that a farmer who knocks down his wasp nest will get no cabbage crop. Now I know why.

Thank you all for your help. Poop had crossed my mind, but I thought for sure they were too big for that since I wasn't seeing the pooper! =) You guys are great.
