They spread diseases such as salmonella, dysentery & typhoid. They will eat anything including human waste.

Control measures for Oriental cockroach:

Cockroach traps should be sited to determine the extent of the infestation. Successful treatment depends upon the method & thorough application of an appropriate insecticide. The insecticide must be positioned in & around harbourages where the pest likes to hide & maintained weekly over the developmental period. Once placed in infested areas, the cockroaches will feed on the gel baits & make contact with a lethal dosage of insecticide. Gel baits offer the opportunity for on- going control of cockroaches over prolonged time periods. They can also be combined with the usage of surface or spray treatments & contact dusts.

Hygiene is of key importance to the control of cockroaches & the following is necessary to eliminate the problem:

  • Prevent access to food & water, this ensures that the cockroach has to move in the direction of insecticides placed.
  • Block any harbourages, which create the ideal hiding place for breeding sites.
  • Create accommodation that is easily cleaned, to avoid the accumulation of debris.
  • Check any incoming materials, including packaging & laundry.
  • Good ventilation systems will speed up the dehydration of the insects & will hinder the operation of antennal chemoreceptors.
