Cockroaches are among the most undesirable insect intruders in the home. They are associated with filth and unsanitary conditions, although they occasionally invade the best-kept homes.
Though known to carry various disease organisms, cockroaches have not been associated with any major disease outbreaks in this country. The insects also produce a secretion that has a repulsive odor and can affect the flavor of food.
Cockroaches can cause allergic reactions when sensitive people come into contact with contaminated food or house dust.
