You're certain that they're termites?

Positive.

Termites eat dead cellulose, not living plants, so while they are present in your soil they probably are not what your problem is.

I am fairly certain they are the problem. As I understand termites are not limited to dead cellulose. I am finding termites in living plants that have just began to strt wilting. I've seen many people with this same problem suggest nematoads. Has anyone had any success with that? Thanks for the feedback.

Please post pictures of your creatures.

Despite many claims there simply is no clear evidence that nematodes control termites. If you have notyet talked with the people at your local Texas A & M Cooperative Extension Office about this do so.

Just wanted to follow up on this. Used a good dose of nematoads and it is working well.
