I would apply the in the spring when I leave to go north for the summer, returning around thanksgiving. Spraying under the home..piers, dirt etc to prevent bugs, roaches etc instead of having a company spray monthly. Is this treatment repeated annually safe.
Cyper TC only has a residual of about 30 days outside and 90 days inside on surfaces so would not provide a full year of killing insects and there is not an insecticide that would do so.
