Termidor SC is a great choice for termite treatments. It lasts 10+ years in the soil if applied as directed. I have included a termite article below for additional information on treating around your structure. If you are going to be treating the wood in the crawlspace, we recommend that you apply Bora-Care if treating for drywood termites.
We recommend that you trench the areas where there is soil and drill 10-12" apart and inject the solution into those areas. You will disperse the same amount of finished solution in the drilled holes as you would the trench, 4 gallons of solution every 10 lineal feet.

Termidor SC has never been tested for bedbugs because it cannot be used indoors. Please take a few minutes to look at our Bedbug Kits for the best product recommendations: Bedbug Kits
