Treatment Options for Roach Control

Bug Lady posted this on Oct 5, 2016

The world of roach control products may be overwhelming for the do it yourself pest controller. In the following article, we review some of the most effective pest control products for the control of small roaches and cockroaches.

Treatment options for a cockroach infestation include:
Glue or “sticky” traps  or  “bait traps” can be used to monitor for any cockroach activity and species identification and are a wonderful option for the do it yourself pest controller. There is no mixing or spraying, so therefore no opportunity for incorrect application. The technology used in some of the traps and bait stations is based on pheromones, not pesticides, making them a viable non toxic option. The roaches are attracted to the pheromone, and then get stuck on the interior glue board.  The home owner is able to inspect the quantity and species that is active in the home, and then just throw away the board once it is full.  It is a safe and easy pest control product that can be used year round, whether or not the homeowner suspects a problem.


There are boric based products that can address numerous pests besides cockroaches. One product is orthoboric acid.  These may be purchased in fine or coarse granules, for use in or outside of the home. Indoor use should be the fine granules for the best consumption rate by small roaches.  They are perfect for dusting under appliances and in wall voids, or in the attics of basements.  Some products can last more than a year in attics or other indoor areas. The outdoor application of these products in the large granule formulation maybe effective for up to 90 days.  These products can be used as a perimeter treatment and will remain fresh even after being exposed to several inches of rain. Orthoboric acid will also control silverfish and ants.  This may be a good multi-purpose pest control product for a homeowner battling numerous pests.
Insecticide sprays can be used on a seasonal or as needed basis to stop cockroaches from becoming a full fledged infestation. Some sprays even contain an IGR, or insect growth regulator,  The IGR (insect growth regulator) provides preventative action, since it disrupts pests’ normal development.  The active ingredient prevents pest larvae from progressing to the adult stage either causing sterility of adults or preventing the emergence of insects from the pupal stage, thereby preventing future infestations.  As a general surface insect spray or spot treatment, the spray is applied to pest harborages providing control for up to four months.


Gel based products can be used inside lower cabinets and crevices that may be allowing entry. A main chemical component of many gel baits is fiprinol. Roach Gel bait should be applied according to label in areas not accessible by children or pets. You will want to apply a small bead into the cracks and crevices as far back as can be reached. Examples would be plumbing penetrations, where cabinets meet the wall, etc. You should look for signs of egg casings and fecal material (they will appear as small black splatters). It is not recommended to spray insecticides near baits, or use heavy detergents or cleaners, or in very dusty area because this will reduce the efficacy of the gel bait, and the probability of the cock roach getting to the bait.


It is possible that your gel bait will dry out and get a dry skin on top but roaches will still eat it up to a year. However, if the gel becomes contaminated or gone, you should reapply.


A good IPM program does rotate baits (bait with different active ingredient) because roaches may not be attracted to the bait matrix of what is being used anymore.  They can be finicky and like most creatures, like a change. The homeowner should be prepared to change baiting products seasonally to keep ahead of the taste buds of home pests.
