Roach spray usually starts working almost immediately on contact—within seconds to a few minutes. However, if it's a residual spray designed to keep killing over time, it can take hours or even days to fully affect roaches that come into contact with treated surfaces. For larger infestations, it may take at least a week to see a noticeable drop in activity, since not all roaches are exposed at once.

Bed bugs are most active when we are most inactive, typically from 2 a.m. until 5 a.m. They are cunning, and adjust their schedules according to their victims. If you work at night, for instance, your bed bugs will flip the script.

For routine pest control maintenance, most specialists recommend treatments every three months (quarterly). However, the ideal frequency can range from monthly to yearly depending on several factors. If you have a severe infestation, more frequent treatments will likely be necessary. Your location also plays a role; for example, homes near water may experience more pests in spring and summer. It's best to discuss your specific situation with a pest control professional to determine a suitable schedule. If you notice any pests between scheduled visits, inform your provider so they can address the issue promptly.

Yes, it’s actually common to see more cockroaches after you spray. It might seem like things are getting worse, but that’s usually a sign the treatment is working. Roach sprays and baits can flush them out of their hiding spots as they try to escape the chemicals. You might notice them acting strangely—slower, twitching, or out during the day when they’re usually hiding.
