Silverfish or firebrats are very active wingless insects. They feed on starchy foods and any materials containing paste or glue. Eggs and adults are easily transported in cardboard boxes and similar containers. Life cycles are completed in three months. Persistent control programs at monthly intervals are probably necessary.
Cockroaches are scavengers and feed on stray food particles.
Many times they are carried into homes on packages. They have filthy habits and hide during the day, coming out at night to feed. Roaches are frequently found around plumbing, sinks, baseboards and cupboards. Eggs, in capsules, are deposited in protected areas, such as behind baseboards or around plumbing. Again they are very persistent pest because the egg capsules will hatch over a long period of time.
