Cockroaches

German cockroaches breed in warm voids near water and food. The regulator reaches the nymphs there and the colony stops replacing itself.

Read the glue board first

Small nymphs on the monitor mean active breeding close by. That is the population the regulator is built for.

Foam the seams, spray the structure

Aerosol through the tube into cracks and appliance voids, concentrate along baseboards and wall lines at one ounce per gallon.

Twisted wings are the tell

Exposed nymphs reach an adult shape with bent, twisted wings and no ability to breed. Seeing them means the material found the harborage.

A cockroach problem is a plumbing-adjacent problem. The colony sits within a few feet of warmth and moisture, behind the stove, under the sink, in the void where the dishwasher drain passes through the cabinet. Treatment that reaches those specific inches beats treatment that covers the whole floor.

Expect the adults to stay visible for weeks after application. They were never the target. The count falls when they age out with nothing behind them, and Complete is the version to reach for when the room cannot wait for that curve.

Rather answer two questions?

The picker asks where the problem lives and hands back the formulation whose label fits that room.
