Hi George –

Thrips can definitely be sneaky pests. If your infestation is heavy, I would suggest pyrethrin to knock down the worst of them and then begin to spot treat other heavily infested areas with Garden Insect Spray (Spinosad). The SNS 209 can also be used, however it is only an all natural pesticide, not a certified organic one, so if you’re not trying to grow certified organic tomatoes, I would give that a try. We have information on all of these products on our website as well as an informational page on thrips that can be found here:

The only plant I can think of to ward them off would be chrysanthemums. Other than that, just keep an eye on the population of thrips (blue sticky traps work wonders for monitoring).

Good luck!
