Caterpillars eating tomato leaves

Just finished picking ~20 of these suckers off my 4 tomato plants. Any suggestions on what to keep them at bay?

Just put some seven spray on them or something like that. Are they those big green bastards with no hair?

Bacillus thuringiensis spores

Last year I watched one go from an inch long to the size of my middle finger in one day eating damn near every leaf on one plant. They make a nice pop when you smash them.

This.

The caterpillars eat it. Their high pH stomach breaks down the crystal bond releasing the bacterial spores. The crystals bind to specific receptors in the gut causing it to tear and the caterpillars stop eating. This allows spores and normal gut bacteria to enter the body. This causes them to become septic and die. I’ve used this stuff for years with great results. Many people get impatient with it because they expect immediate results out of them. But the caterpillars usually take a few days to die. Good news is they do stop eating only hours after ingesting it. I find it a better long term solution to controlling caterpillars as opposed to contact poisons.

Don’t delay doing something, as they’ll eat every leaf off the plant in a couple of days. Just pick them off and smash them. If you have trouble seeing them all, just look for their crap below the plant.

Thuricide? I've always been concerned with using sevin dust out of fear it would kill pollinators. I haven't put anything on my tomatoes yet this year and would like to be more proactive with it. I also have swiss chard that gets nuked by caterpillars once the weather gets hot.

Those bastards will mow down every plant you have in matter of days. And they are camo so if you pick at them, you wont get all of them.

Get a bottle of Sevin concentrate. Mix 4oz with 1 gal of water. Spray your plants. Watch those evil things die. There will be little green turds falling out of the plants.

Yep. That’s one of the trade names.

I can spray the Bacillus on the fruit as well or do I need to avoid the flowers/fruit?

They glow with under UV light. Pick up a cheap blacklight flashlight and pick them off at night. The kiddos have a ball with this.

You don't have to avoid them. It's harmless to pollinators and humans.

you can also plant marigolds with your tomato plants, get pretty flowers and they repel the moths from laying on your plants

Mix 2 tsp per gal water. Spray once a week or after heavy rain. Safe to use. Spray today, pick veggies to eat next day.

My chickens LOVE those things.

when we start getting them later in the summer I'll get them and throw them in with the chickens. They'll fight for them.
