Generally speaking, control measures should concentrate
on the outside of the building and points of entry of the American Roach.
This is called a "perimeter
or barrier" treatment.
You may use concentrated residual sprays : D-Fense SC, Cyzmic CS, Cyper
WP or Demon WP inside or outside.
Spray a 3-6 foot band around the entire house. Spray outside around doors, windows, pipe openings, and dryer vents.
Recommended products are in the table below. They would require a pump sprayers.
Insecticide Granulars : You may apply
granulars around the base of the house, particularly in areas of pine
straw and mulched areas.
Granular Insect Baits:
Insects baits like Invict Xpress Granular Bait can be used indoors, outdoors or in turf areas. Invict Xpress has multiple food attractants to attract not only the American Roach, but also Crickets, some Ants, Silverfish, Earwigs and Firebrats
Apply also on the inside on the baseboards near the entry pts.
On the inside-apply around the plumbing under the sinks and washer and
dryer connections. You don't have to spray all the interior baseboards,
just the corners and baseboards inside the garage and basement areas.
If you have these larger cockroaches entering inside your
home from the attic area (due to trees that overhang the attic or gutters
that are not clean) using baits like Invict Express Insect Baits, would give you very good results. This insect bait would also be excellent choices for
crawl spaces and or attics.
Dusting with a hand duster where the American roaches would be traveling. Such places would be behind baseboards, wall outlets, wall voids and underneath appliances. The recommended dust is D-Fense Dust.

every three months during the season.
The Invict Xpress Granular and D-Fense Dust last from 6 months to a year, free from rain.
