Hey all, As the title suggests, I got a pest problem. I’ve tried diatomaceous Earth and spinosad spray, neither of which seem to work. I’m pretty sure they’ve killed my crop for this year. I’m wondering what you all do. I’m trying to avoid truly nasty pesticides, and I honestly don’t have the drive to physically remove them, so for me, those two options are right out. I’m willing to keep trying spinosad, I think it’s mostly that it rains a day or two later, and it’s gone by the time the next batch of eggs hatch. Any suggestions are appreciated.
Diatomaceous earth only works when it’s dry, fyi, so that can be tricky directly in the garden where things are bound to get wet.
I’ve heard that peppermint essential oil can deter insects, but it does come with the side effect of smelling like you live inside a diner mint, for better or worse.
Oh boy you’re in for a battle. We’ve had squash bugs now for the second year and they are aggressive and once they’ve produced a few generations they are near impossible to get rid of. We’ve gotten to the point where we’re not going to plant any squash for a couple years because they overwinter in the soil.
Your best bet is to get the eggs off the leaves before they hatch. I like to use a piece of duct tape to pull the eggs off. If you get to it early you can stop an infestation. But if you have eggs on nearly every leaf then it’s too late. Even with heavy pesticides the cycle is hard to break. If the eggs hatch you can still kill the nymphs pretty easily with natural things like diatomaceous earth or Castile soap spray, but once the nymphs molt and turn to adult they cannot be killed without something like sevin pesticide (which will also kill beneficial bugs.)
Good luck.
Oof! Good luck. I gave up most years because they’re such a nuisance. I did have small luck with vinigar and peppermint, but only very small.
Also, grasshoppers…holy halibuts, batman! I’ve never seen something sheer gourds to nothing like this year. So even trying gourds to deal with the squash bugs didn’t work.
Next year, they planing strongly scented mint-family plants between squash plants. Mint, rosemary, sage, etc. will deter reduce pest activity, though it usually won’t work 100%. I like to use lemon balm just so I can snack on it when I’m tending the garden.
Mint can be pretty invasive depending on where you live. We have a smaller bed near our house that it’s basically taken over, but that’s largely OK with us. I would hesitate to put it into the ground in my raised beds.
Does work though. I used it near strawberries for the same kinda effect and it does keep insects further away.
I ended up pulling it all out though cause the creep was getting bad. I feel like lemon balm or citronella is gonna be my next test.
