Types of cockroaches in Mexico: which are the most common?

Most common types of cockroaches in Mexico and how to control them

In Mexico, the most common cockroaches in homes, businesses and industries are:

1. German cockroach (Blattella germanica)

• Size: 1.3–1.6 cm
• Color: light brown with two dark parallel stripes behind the head
• Habitat: warm, humid places (kitchens, bathrooms, pantries, cracks and dark corners)
• Risks: contaminates food and utensils, spreads bacteria and allergens, reproduces very fast and creates large infestations in little time.

1. American cockroach (Periplaneta americana)

• Size: up to 4 cm
• Color: reddish brown
• Flight ability: can fly, though it usually walks
• Habitat: very humid environments such as sewers, basements and warehouses, in both residential and industrial areas; hides where organic matter accumulates. This is the well-known sewer or drain cockroach.
• Risks: carries agents of gastrointestinal diseases and can transmit pathogens on contact with surfaces and food; in large numbers it creates unsanitary conditions.

1. Oriental cockroach (Blatta orientalis)

• Size: 2–3 cm
• Color: shiny black
• Movement: slower than other species
• Habitat: prefers cool, damp places (basements, drains, areas with garbage and persistent moisture)
• Risks: contaminates food and surfaces, is associated with hygiene and health problems, and often signals water leaks or maintenance deficiencies.

1. Brown-banded cockroach (Supella longipalpa)

• Size: ~1.5 cm
• Color and traits: two brown bands across the body
• Habitat: dry, warm environments; hides in furniture, behind picture frames and in high areas (offices, bedrooms, living rooms); avoids moisture and uses small, warm hiding spots
• Risks: carries health-affecting microorganisms, infests furniture and storage areas; its small size lets it reach many corners.

What to do if you find cockroaches

If you find cockroaches, act fast: remove their food and water sources, store food in sealed containers, take out the trash often, and seal cracks and hiding spots in the kitchen and bathroom. They are more than a nuisance — according to the Asthma and Allergy Foundation of America (AAFA), cockroach residue is a common trigger of asthma and allergies, and these insects can carry bacteria onto kitchen surfaces. When an infestation persists, professionally applied integrated pest management (IPM) is the most effective way to eliminate them for good.

If you see one cockroach, there are very likely many more hidden; we recommend reading how to prevent a roach infestation at home. To reduce the problem right away:

• Keep everything clean: sweep, mop and wipe surfaces to remove food scraps and standing water.
• Seal cracks and gaps: use sealant or silicone on doors, windows, pipe runs and corners.
• Store food properly: use airtight containers and avoid leaving food uncovered.
• Don't pile up cardboard or paper: get rid of unnecessary boxes and papers, since cockroaches hide and breed in them.
• Place traps or baits: they can help lower the population while the problem is still small.

If you keep seeing cockroaches despite these measures, the best option is a professional pest control service. We compare both options in cockroaches at home: DIY or professional fumigation?

Frequently asked questions about cockroach types

How many types of cockroaches are there?

There are more than 4,500 species of cockroaches worldwide, but only around 30 live alongside people. In Mexico, the ones that most often become pests in homes and businesses are the German, American, Oriental and brown-banded cockroaches.

Which cockroaches are most common in Mexico?

The German cockroach is the most frequent in kitchens and food areas due to its fast reproduction, while the American cockroach (the largest) is usually found in drains, sewers and basements. Identifying the species is key to choosing the right control treatment.

Can cockroaches fly?

Some species, such as the American cockroach, have wings and can glide short distances, especially in warm environments. Others, like the Oriental cockroach, barely use them. In general they are better runners than fliers.

How do you eliminate cockroaches from your home for good?

Permanent elimination combines hygiene, sealing cracks and removing water and food sources with a professional treatment targeted at the species present. At Fucesa we apply certified gels, baits and sprays, along with follow-up, to break the reproduction cycle and prevent reinfestations.
