Effective control is easier in temperate climates (where cockroach populations
cannot survive outdoors in winter) than in humid and warm areas. The key to
control is cleanliness, which may be difficult in houses where there are children
and domestic animals. In isolated homes, control is easier to achieve than in
apartments where cockroaches may have easy access from adjacent quarters.
Reinfestation occurs from outdoors in warm areas, or along heating ducts and
water pipes in apartments, or from groceries or luggage brought from cockroachinfested
areas. Cockroaches may even sometimes be found in very clean houses,
but are unlikely to establish colonies.
The presence of several sizes of nymphs and oothecae is an indication of a wellestablished
colony. Infestations can be detected by searching behind skirtingboards,
boxes, furniture and other common hiding places. At night, cockroaches
are easily detected using light.
