cockroachCockroaches are pests that can contaminate food and spread disease by walking over, and excreting on food or food preparation areas after having travelled through garbage or sewers. People with asthma may have a negative reaction to their feces and body parts.

The most common household cockroach in Canada measures about 1.3 cm to 1.6 cm long. It is tan to light brown with two dark parallel streaks running from the head to the base of the wings. They have wings, but are hardly able to fly.

• Because cockroaches are most active at night, they may go unnoticed for some time.
• Cockroaches hide in cracks and prefer warm and damp areas (kitchen, bathroom, basement) where there are food fragments.

Strict sanitation measures combined with pesticide use are essential to eradication.
