When should I spray again? Should I add anything else? I have several different kinds of roaches I think.
Alpine WSG https://www.domyown.com/alpine-wsg-p-2876.html has a residual of 30-60 days so retreatment may be done after 30 days. How long it takes to kill insects depends on a few factors such as age and health of the insect, how long they spend on the treated surface and how soon after application they contact it. How long it takes to eliminate a roach infestation depends on how large the infestation is, how consistent and thorough you are being with treatments and what products you are using. There is not a set time; it can take but it can take weeks or months even to get complete control. Alpine WSG is typically not used alone but in combination with other products. We would recommend one of our roach control kits. You can see the kits by clicking on the link here. We also have a great article for eliminating them that can offer some great advice; you can find it here.
