Odorous House Ant

Natural Habitat

Typically found in nests under rocks, logs, or mulch outdoors, but often enters human dwellings to forage or seek shelter during rainy weather.

Diet & Feeding

Opportunistic omnivores that prefer sweets (nectar/honeydew) but will also consume grease, meat, and dead insects.

Behavior Patterns

They are known for traveling in distinct foraging trails; if crushed, they emit a pungent, rotten coconut-like odor. They form multi-queen colonies and are very resilient.

Risks & Benefits

They do not bite or sting and pose no health risk, but they are considered a major nuisance pest when they contaminate stored food in kitchens. They provide ecosystem benefits as scavengers and decomposers.
