Behavior:

Perhaps one of the most common ant species found indoors across Oklahoma, the odorous house ant gets its name from the strong, rotten coconut-like smell it gives off when crushed. These tiny brown ants range in size from one-sixteenth of an inch to one-eighth of an inch long. 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. Outdoors, odorous house ants will typically be found near sidewalks and driveways, in exposed soil or under stacks of debris. When they make their way indoors, Odorous house ants will typically stay near water sources to build their nests making them a common pest around water pipes or beneath leaky fixtures.

Prevention:

Focus on sanitation, sealing entry points, and eliminating moisture sources, while also maintaining a clean environment and removing potential food sources. Here’s a more detailed approach:
Clean spills and crumbs immediately, especially in the kitchen and dining areas. Regularly vacuum and sweep to remove food particles and debris. Wipe down countertops and surfaces regularly. Take out the trash frequently and ensure trash bins are tightly covered.
Store food, especially sweets and grains, in airtight containers. Remove pet food bowls when pets are not eating. Inspect your home for cracks and gaps around windows, doors, and foundations, and seal them with caulk or weatherstripping. Repair any cracks in the foundation or exterior walls. Trim back trees and shrubs that are touching the house, as ants can use them as entry points. Keep woodpiles away from the house, as ants may nest in them. Repair any leaky faucets or pipes promptly. Fix any condensation issues. Ensure proper water drainage away from the building foundation. Use non-moisture retaining mulch in flowerbeds around the building foundation.
