Holes In Tomatoes

I'm looking for suggestions as to what might be chewing holes in my tomatoes.
I'm finding a great deal of tomatoes (green or otherwise) with a single hole eaten in them. I cut them open and there aren't any worms or other critters inside and I don't see any evindence of slugs (ie trails). I treat them every two weeks with Bt, just in case but it's still persistent. I wouldn't be so upset if one or two tomatoes were eaten but it seems almost half of them have this 1/4 wide inch hole bored in them, to a depth of about the same and mostly it's only a single hole.
I visually scoured the plants ( I only have six) to pick out any culprits and all I found were a couple of stink bugs, one slug on the ground and no sign of horn worms.
Any ideas?
Thanks.

Try some bird netting and see if that helps?

I'm having the same problem & this morning found the culprit while picking. It was a corn ear worm. I guess it has been so dry that they are looking for moisture any where. I sprayed with Bt, that should cure the problem Steve

You must remember that it takes awhile for the Bt to create a defense in your garden. As all those little bacteria need to reproduce and then really infect target insects. In the mean time, try a little mixture of dish soap and hot pepper sauce sprayed on them.

Grasshoppers will sometimes cause this damage.

Ooh, I tend to forget about those buggers. They live on my poor cannas every year so pretty much leave the veggie garden alone when I'm actually growing one.
There is supposed to be a "bug" (fatal bacterium) you can put out for them too, but it only affects the nymph stage, so must be put out in the spring.
Gotta love biological warfare against garden pests. ;-)
