MotherHen68 from The Chicken Coop asked us:
Any suggestions on how to prevent my squash from getting those nasty green worms that demolish the entire plant? I’m guessing these are squash vine borers and the offending egg layer is a brown moth. I’d rather not use poison, but I’m fed up. Thanks!

What it sounds like you have may be armyworms or some other type of caterpillar. My recommendation is first to use row covers over your squash when you plant them and leave the covers on until they start to flower. When you remove your row covers just keep an eye out for these pests. If you start to see them you can hand pick them. If the population gets to be too much, you can spray the plants with Bt, which you can find at nearly any plant nursery. Bt, or Bacillus thuringiensis, is a bacteria found naturally in soil that produces a toxin that is fatal to soft bodied insects usch as caterpillars. It is safe around all other animals, including humans and breaks down rather rapidly once applied.
Also practice crop rotation and companion plantings to deter these pests.
Good luck and I hope next year you get a bumper crop!
Great advice. This is the first year we've used row covers extensively. For the squash I'm glad we did, if only because it helped to protect them from leaf miners. The minute the covers were off, they showed up, but by then the plants were large enough to hold their own against the bugs (and the chickens too! :P).
Thanks so much for your advice! I was thinking next year of using row covers, but I hadn't heard of Bt. I'm going to look into it.
I'm planning a brand new bed for my squash for next spring, so I'm hoping for a good harvest!
