Scorpions love to hide in cracks or voids of houses and buildings. This can be a crack in your block wall, gaps in your retaining wall, pool deck drain tracks, and around your home where the stucco meets the concrete at the bottom of your home. Foaming we feel brings the best results and longer residual, which means it last longer therefore can kill scorpions for a longer period of time. Our customers that try the foaming love the results! You can see in the pictures how the foam solutions looks when applied into the cracks. Chemicals are then applied with a foaming agent that when injected looks like shaving cream and will expand into the whole void. Eliminating any hiding places from the scorpions or any other insects that may be hiding in there like like crickets or roaches. Foaming also gives the chemicals more time to adhere to the porous surface which results in longer lasting effects.
