Cockroaches

Cockroaches (order Blattodea) are insects that have existed for over 300 million years. In Mexico, the most common species are the American cockroach (Periplaneta americana), the German cockroach (Blattella germanica), and the brown-banded cockroach (Supella longipalpa). They are urban pests that reproduce rapidly and can infest homes, restaurants, and commercial spaces.

Identification

• Size: From 1.5 to 5 cm depending on the species.
• Color: Light brown to dark brown or reddish.
• Body: Oval and flattened, with long filiform antennae.
• Wings: Some species have developed wings, although they rarely fly.
• Habitat: Warm, humid, and dark places: kitchens, bathrooms, drains, behind appliances.
• Activity: Primarily nocturnal. Daytime sightings may indicate a severe infestation.

Frequently Asked Questions

Do cockroaches transmit diseases? Yes, they can carry bacteria such as Salmonella, E. coli, and Staphylococcus, and can cause allergic reactions and aggravate asthma.

Why are there cockroaches in my clean house? Cockroaches can enter through pipes, cracks, and packaging. Cleanliness reduces the risk but does not eliminate it completely.

Can cockroaches survive without a head? Yes, they can survive up to a week without a head thanks to their open circulatory system. They die from dehydration.

Hazards

Cockroaches contaminate food and surfaces with pathogenic bacteria. Their droppings, molts, and body parts are known allergens that can trigger asthma, especially in children. In commercial and industrial settings, an infestation can result in health code violations, product loss, and reputational damage.

Control and Prevention

• Crack sealing: Close entry points in walls, pipes, and door frames.
• Waste management: Keep trash in sealed containers and remove it frequently.
• Moisture elimination: Repair leaks and keep areas dry.
• Food storage: Store food in airtight containers.
• Professional control: Application of insecticidal gel, spraying, thermal fogging, and monitoring traps by certified technicians.
