We would recommend using Temprid SC. It has two different active ingredients in it which provide a powerful and effective residual and a quick knockdown. If the infestation is bad, we would recommend using 16 mL per gallon of water and if it is moderate/low, use 8 mL per gallon of water. It does last for up to 90 days indoors and 30 days outdoors. It is labeled for ants, roaches, spiders and various other pests as well. When spraying indoors, you will spray along the baseboards and cracks and crevices. When spraying outdoors, you will spray around the perimeter of the structure.
Another good thing to prevent pests would be to dust inside the wall voids. You will take off the light sockets and electrical outlets. This will create more of a long term treatment for various pests. You will use a hand duster and do a couple of puffs per outlet/socket. We would recommend using Delta Dust. It is waterproof so if it gets what for any reason, it will still work. Also, it lasts inside the wall voids for up to 8 months if it is undisturbed.
