I am first time gardener. I did lot of research, it looks like i have pinworms attacking my plant. I have seen hole in tomatoes and seen small worm /caterpillar in leaves. I have culled a lot leaves. I live in central NJ zone 7a.
My question is 2 part.
Is it worth it to buy Bt to kill the worms now? i have a few tomatoes that will take couple of weeks to ripen.
Does Bt expire?
I have learned a lot this yea between deer eating my plants, ground hog eating my tomatoes and now pinworms.
