Mike writes,

What is the best product for use around the house, Demon WP or Suspend SC?

Have had some success with your Suspend product with the fire ants and large roaches. Silverfish are already in the house. Neighbors are recommending your Demon product for better barrier control for ants and roaches. Please recommend best overall product. Also recommend product for Silverfish.


Suspend SC and Demon WP are both synthetic pyrethroid products and both offer great control of the pests you mentioned. Demon WP will last a bit longer outdoors and since it is a wettable powder it also stays on the surface of porous areas such as concrete or wood which creates a greater opportunity for insects to come into contact with it. The downside to this is that Demon WP will leave behind a white powdery residue that is especially noticeable on dark surfaces. Both Demon WP and Suspend SC can be used indoors for silverfish control but because of the white powdery residue that Demon WP can leave behind it may be best to stick with Suspend SC for this use. You can also use Dekko Silverfish Paks to help control the silverfish in hidden areas indoors. Silverfish simply eat through the pack and ingest the poison inside. Place in closets, drawers, bookcases, basements, garages and other dark hidden places. Each pack lasts up to 4 months.
