What Do Cockroaches Smell Like? How to Identify Roach Odors

“I think I have a cockroach infestation but can’t find any nests. What do roaches smell like?”

A cockroach infestation can smell like a mixture of pheromones, shed skin, droppings, and decaying insects. You might have noticed a lingering sweet odor, or just smells you aren’t used to in different parts of the home.

If you have cockroaches, what they smell like will depend on their species:

• American cockroaches: These have an earthy or musty smell, like being in an old house. You might sniff them out in basements, attics, or around drains and crawlspaces.
• Oriental cockroaches: These have a more damp or mildewy smell, almost like stagnant water. They are usually found in damp areas, such as bathrooms or around drains.
• German cockroaches: These roaches usually have a greasy or oily smell. They are typically found around kitchens or other indoor spaces.

While the smell can be a good indicator, confirming an infestation by scent alone is tricky and unreliable. If you have cockroaches, you’ll usually find other evidence such as:

• Discarded chitin or shed skin
• Droppings
• Egg cases
• Smear marks
• Tiny bite marks on packaging or cardboard
• Dead roaches

If it gets to the point where the smell is particularly strong, you may already have a significant infestation. If so, speak to JP Pest Control to arrange a cockroach control service.
