Dealing with horn worms on the tomato plants

We weren’t in the garden for about 4 days and I missed the signs of horn worms until they had done some serious damage.  We went through our plants and plucked off any horn worm caterpillars we spotted.  They’re in a canned chicken can on top of a 2 gallon bucket in the picture below.

After removing all of them we were able to see I mixed up a batch of BT and sprayed all the plants. The next day I went out and found ones that we had missed dead and hanging from plants.
