The initial treatment is very aggressive, and once it is done, over 95% of the bed bug population will be eliminated. The insecticides we apply after vacuuming and steaming will kill the remaining population. For homes with light bed bug activity, it is possible to stop seeing bed bugs right after the first treatment. However, a recently fed adult hiding in a void, for example behind a baseboard, may take a few days to get hungry and start looking for another blood meal. As soon as they come out to feed, they will intercept our chemical treatments and every single one will die. Most customers stop seeing bed bugs two to three weeks after the initial treatment. Regardless, every bed bug service includes a follow-up inspection 30 days later by an expert technician to be certain they are completely gone. If needed, we will do a touch-up service and come back for a second inspection.
