I am unable to fit in the crawlspace on the part of my house that the termites are using. If I treat just the outside will it be equally as effective?
Termidor SC is a great choice for liquid soil treatment since it has a very long soil residual (10 years or more) and great transfer effect. In preventative applications, you would not be required to treat the inside of a crawl space. However, if there are live termites in the crawl space, then you would still need to spot treat that colony to insure control of them. So just treating the exterior of the house is not considered sufficient if there is already an issue in the crawl space.
If you can treat the termites from elsewhere in the house, then you may be able to spot treat the activity using Termidor Foam instead.
