The Surinam cockroach is listed in our group of
Large Outdoor Roaches. This cockroach is usually found outdoors, though it
can migrate indoors. The best method of controlling Surinam cockroach
infestations is to alter its outdoor habitat (if possible) and to treat the
exterior of homes and buildings as you would for other large, outdoor roaches.
Professional granular roach baits scattered in mulched areas and flower beds or other landscaped areas where the Surinam frequents will often control outdoor infestations. Once outdoor areas are free of roaches, rarely are they found indoors. When potted plants are moved from outdoors to indoors, any of the outdoor roaches (such as the Surinam, Smoky Brown, etc.) will often hitch-hike into homes.
If a spray is preferred, any of the long lasting insecticides will do a good job. There does not seem to be much of a pesticide resistance in this insect, so any professional insecticides labeled for the areas to be treated will suffice.
Demon WP, Cynoff WP, Demon Max, Cynoff EC, Demand CS and Suspend SC will all to a good job. If ornamentals need spraying, choose an insecticide that is labeled for spraying plants to avoid damage to foliage which might endanger the plant. Talstar One and Suspend SC are both labeled for spraying turf and ornamentals. Talstar One usually gives a longer residual; Suspend can be used indoors as well as outdoors.
