Debi writes,

Will Onslaught continue to kill black widow and brown recluse spiders even after it has dried?


Yes. Onslaught will leave a long lasting residual that will continue to kill spiders for a month or more. Onslaught will also help get rid of the insects that spiders feed upon which helps to prevent new spiders from moving in.
