Fipronil - Plus - C can be used indoors for roaches however per the product label, for German cockroaches applications must be directly sprayed within the void to be killed. This product cannot be sprayed around the perimeters inside, along baseboards, behind appliances, under sinks, etc. We would recommend using one of our Roach Control Kits for a complete treatment program using a residual insecticide, roach bait gel and insect growth regulator. Take a moment to view our How to Get Rid of Roaches Treatment Guide for step by instructions.
