Most common reasons why it happens…

Roaches Are Forced Out of Hiding

When pest control agents treat your home, they disturb roaches hiding in cracks, crevices, and walls. As a result, more roaches may be visible temporarily as they try to flee from their hiding spots.

Extermination Takes Time

Most pest control treatments do not kill roaches instantly. Cockroaches must come into contact with the pesticide, which can take few days to be effective. In the meantime, you might see more roaches before the treatment fully works.

Roaches Are Seeking New Hiding Spots

After being exposed to pesticides, roaches may leave their current hiding places and search for new ones. This can cause you to spot more roaches as they roam the house.

Dead Roaches Are Still Visible

Some of the roaches may have already been killed by the pesticide, but they haven’t yet died or been removed from your home. You might see dead bodies during this time, which can give the illusion of a larger infestation.

Reinfestation

If the treatment didn’t address the root of the problem or if there are outside sources of roaches, reinfestation can occur. This is more likely if you haven’t implemented preventive measures after the treatment, such as sealing cracks & eliminating food sources.

Seeing more roaches immediately after pest control is often a sign that the treatment is working. If the problem persists, follow-up treatments or additional preventive measures may be needed to fully eliminate the infestation.
