Similarly, do the residual effects last longer on hard, non-porous surfaces (like polished wood, polished metal, and hard plastics) or on softer porous surfaces (like fabric, and unfinished wood)? Thanks!
Per a technical specialist at Bayer regarding the efficacy of the Temprid FX: It is not a question of efficacy of the active ingredients changing on different surfaces (as long as all are chemically neutral), but the amount of exposure to residues based on interference by the physical properties of the surface. Temprid (or any other residual insecticide) would generally be more efficacious (with all other factors like UV exposure, relative humidity, temperature exposures, surface pH being equal) against bed bugs on a hard, non-porous surface because if applied at the same amount, you would expect more of the deposit on the non-porous surface to be available for exposure to the target pest than on a porous surface. When using Temprid FX Insecticide for bed bugs you are only applying to cracks and crevices and along baseboards in rooms, not across entire surfaces. Please refer to the product label for complete instructions.
