Any pesticide type product that is intended to kill insects also carries with it some potential danger to humans, particularly if used improperly.
Products such as this, although intended for use indoors, must be used very carefully and according to product label. Special precautions must be taken as indicated on the label, if it is felt that insect control indoors is needed. Only products intended for use indoors should ever be used to control insects in a home.
If insect problems persist a professional exterminator should be called.
