COCKROACH CONTROL OPTIONS
Cockroaches are among the most common insect pests found inside buildings. They are a nuisance for both their repulsiveness to people,as well as for the diseases they spread. Some say that cockroaches are in fact clean insects, but this is a fallacy. Moving between waste and filth, they can spread microorganisms that cause food poisoning and other illnesses.
What you do to control cockroaches:
Sanitation is an important step in preventing problems since they flourish
where food, moisture and shelter are readily available. Crumbs, spills
and grease should be cleaned up and unwashed dishes and food should
not be left out overnight.
Pest proofing will help by sealing all cracks and crevices where they hide. Make sure there are no openings to the outside where plumbing and cabling go through the walls.
Sprays should be applied carefully so as to avoid contaminating foodstuffs and should be focused to where they hide.
Baits can also be very effective since this attracts them despite food being present.
Natural remedies, such as diatomaceous earth and borax have been used with some success.

Insecticides are usually required to eliminate an existing cockroach problem. Emphasis needs to be on finding and treating cockroach harbourages. This may include residual sprays, non-residual residual sprays and IGR’s (insect growth regulators). Drains are also sprayed for the larger Americana cockroaches.
Baits are attractive to cockroaches since they contain pheromone attractants which will be chosen over food. These contain a slow-acting insecticide, causing the cockroaches to die within a few days. They often take it back to the harbourages where other cockroaches are also contaminated. Cockroaches are also cannibalistic and so will eat contaminated cockroaches.
Insecticide dusts are used for treating wall voids and hollow spaces beneath and behind cabinet and appliances.This is also
placed inside cockroach harbourages.
Once treatment commences,cockroaches will begin scurrying around, and we use this opportunity to vacuum these, and those hiding in their harbourages. This quickly reduces the population, allowing for less survivors.
Monitoring traps aid us in several ways. They allow us to see what life-stages are present (catching only adults may indicate that they arrived recently in boxes or other items). They can indicate which direction they came from (where they are caught in the trap). And they can also, although minor, reduce the cockroaches present since they are caught.
