Odorous house ants like to eat sweets and are especially fond of honeydew. They are known to move their nests every three months or so in response to rain.
Indoors, odorous house ants nest near moisture sources, such as in wall voids near hot water pipers, in heaters, beneath leaky fixtures and inside wood damaged by termites. Outside, odorous ants are often found in exposed soil or under stacks of firewood.
Odorous house ants do not pose a public health risk, but they can contaminate food and should be avoided. If you notice odorous ants in your property, contact an ant pest control specialist.
