- Nymph and adult Orientals prefer to be at or below ground level, and are rarely found on walls, in high cupboards, or on the upper levels of buildings.
- Oriental Cockroaches prefers starchy food and any kind of filth, rubbish, or decayed organic matter in compost or mulch piles.
- Oriental Cockroaches can live for a whole month without food if water is available; without water, the roach will die within 2 weeks.

- Egg capsule are attached to protected surfaces near a food supply.
- Adult female Oriental Cockroaches produce about 8 egg capsules, containing 16 eggs each which will hatch within 60 days
- Oriental cockroaches have a seasonal developmental cycle, with the highest number of adults usually appearing in late spring and early summer, with nymphs predominating in late summer and early fall.
- Nymphs that have not reached maturity by late fall or early winter, will usually not reach adulthood until the following spring.
Basic Control Methods
- Remove food and water sources for roaches by practicing good sanitation, vacuuming daily, keeping foodstuffs in tightly sealed containers, and removing standing water wherever possible
- Limit roach harborages by caulking cracks and crevices, repairing torn screens, and sealing holes around pipes and other fixtures with copper mesh
- Monitor roach populations and pinpoint "hot spots" with sticky glue traps in suspected high-travel zones
- Use a Boric Acid or Delta Dust in wall voids, behind outlets, under baseboards, and all other cracks and crevices where roaches hide.
- For indoor control, use Maxforce Gel Roach Bait in infested areas. Do not spray or use other pesticides in the same area where bait is being used.
