No, cockroaches are not attracted to blood in the way that some other insects like mosquitoes are. They do not feed directly on human blood.
Why Cockroaches Don't Seek Blood
Unlike insects that specifically target blood for sustenance, like mosquitoes, ticks, and fleas, cockroaches have different feeding habits. Here's why they don't target blood:
- Dietary Preferences: Cockroaches are omnivores, meaning they eat a wide variety of organic matter. Their diet includes decaying food, paper, cardboard, grease, and other readily available substances.
- Lack of Blood-Sucking Adaptations: They do not possess the necessary mouthparts to pierce skin and suck blood.
- Not Disease Vectors (Directly): While cockroaches can carry germs on their bodies, they do not transmit diseases through blood-feeding as mosquitoes or ticks do.
As stated in the provided reference, "roaches aren't disease vectors, and they do not feed directly on our blood, skin or fluids."
What Attracts Cockroaches
Instead of blood, cockroaches are attracted to:
- Food Sources: Crumbs, spills, and open food containers.
- Water: Leaky pipes, damp areas, and pet water bowls.
- Shelter: Dark, warm, and secluded places like cracks, crevices, and under appliances.
- Decaying Organic Matter: Garbage, compost, and other waste.
How to Prevent Cockroaches
To keep cockroaches away, it is important to focus on removing their preferred food, water and shelter:
- Keep your kitchen clean, and promptly clean up spills and crumbs.
- Store food in airtight containers.
- Fix leaky pipes and faucets to reduce moisture.
- Seal cracks and crevices in your home.
- Empty garbage bins regularly.
