I sprayed indoors for a silverfish problem and have noticed great results up until today. It's only been 3 weeks since I applied, but I've found two alive this morning and have read the residual doesn't last as long as the label states (90 days indoors). I've been planning to reapply every 30 days until the issue is resolved, however, is it too soon to spray again today (3 weeks)?
The residual of Onslaught FastCap should last at least 90 days inside and you would reapply that often and not sooner. Please also take a moment to read over our article on how to treat for silverfish for helpful tips. There are three types of products we recommend using to combat a silverfish infestation: silverfish packs, perimeter bait, and insecticide. By using all three products in conjunction with one another, you will have the most success controlling your infestation.
