Roaches (Blattaria or Blattodea)

Cockroaches are one of the most commonly noted household pest insects. They feed on human and pet food and can leave an offensive odor and stains on nesting surfaces. They can also passively transport microbes on their body surfaces including those that are potentially dangerous to humans, particularly in young and elderly individuals. Cockroaches are also linked with allergic reactions in humans and asthma attacks.

General preventive measures against household pests include keeping all water and food stored away in sealed containers, using garbage cans with tight lids, frequent cleaning in the kitchen, and regular vacuuming. Any water leaks, such as dripping taps, should also be repaired. It is also helpful to seal off any entry points, such as holes around baseboards, between kitchen cabinets, pipes, doors, and windows with some steel wool or copper mesh and some cement, putty or silicone caulk.
