What's the Best Cockroach Killer: Baits or Sprays?
What Are the Health Risks of Cockroaches?
Cockroaches eat and defecate as they go, contaminating food and utensils. They are a significant household sanitary pest. Here's how they cause harm:
- Spreading Germs
Cockroaches carry more than 40 types of pathogens on their bodies, including Salmonella, E. coli, and Shigella, spreading them via their legs, mouthparts, and body surfaces. They may also carry parasite eggs such as roundworm eggs and amoebic cysts. They crawl back and forth between garbage and food, distributing germs everywhere.
- Triggering Allergies
Cockroach shed skins, droppings, and saliva contain allergens that can trigger allergies and asthma in some people. Cockroach allergens are a significant trigger for childhood asthma — especially for people with sensitivities, long-term exposure can provoke respiratory symptoms.
- Damaging Property
Cockroaches also chew on books, clothing, leather goods, and electrical wiring. When food is scarce, they may even gnaw on fingernails and skin keratin.
- Psychological Impact
Having cockroaches at home isn't just disgusting to look at — the sound of them scurrying around at night can also affect your quality of sleep.
