Termidor SC, when used as directed, is safe to use with people inside the home and you do not have to evacuate anyone from the premises. It should be perfectly safe for a pregnant woman since you will be treating outside.
Termidor is labeled to control roaches but it’s not labeled to be used indoors. Please take a look at our Roach Control Guide for information on how to control roaches. We also have Roach Kits that have the products you need to do a roach treatment indoors.
If you are able to access the soil around the pipes, yes, it would be recommended to treat the top few inches with Termidor SC around them. There is no harmful fumes released.
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
