Odorous house ants (Tapinoma sessile) are small, fast-moving ants that form large colonies and build nests in wall voids, beneath mulch, and inside structural gaps. Infestations can lead to food contamination, and the strong, unpleasant odor they release makes them unwelcome guests in any property.
Identification
An odorous house ant infestation can easily go unnoticed. If disturbed, they’ll scatter, making detection more difficult. One subtle feature is the uneven shape of their thorax when viewed from the side, and the smooth, uniform appearance. Unlike some other ant species, they don’t have stingers or strong jaws, but their numbers and activity can increase rapidly once they locate a steady supply of food indoors.
Habitat
Warm areas with plenty of moisture are especially attractive. Outdoors, odorous house ants shelter beneath items that provide cover, such as garden stones, boards, piles of mulch, or yard debris. Inside, they like to settle in hidden, damp spaces behind tiles, under sinks, or within structural gaps near plumbing lines. Capable of relocating quickly, colonies may shift locations in response to weather, environmental disturbances, or changes in food access.
Odorous House Ants in Florida
Florida has the ideal climate for odorous house ant habitats. During wet seasons, they may leave outdoor nests and search for dry shelter and steady food sources inside. Their outdoor diet includes honeydew from insects like aphids and mealybugs, while indoors, sugary and greasy foods become targets. There is little conflict between colonies, allowing them to expand rapidly across multiple locations.
Odorous House Ants Behaviors, Threats, or Dangers
Odorous house ants do not sting or carry venom, but their presence indoors can still cause problems. A key aspect of odorous house ant behavior is their use of scent trails during foraging, which guides large numbers from the same ant colony to a food source. This means indoor activity can quickly escalate. Though small, these ants can contaminate food, which can be a health risk. When you notice trails of ants around entry points, countertops, or storage areas, it’s time to speak with an experienced pest control professional.
Are Odorous House Ants Hard to Get Rid of?
The ants can move around and nest in hidden spots. This makes getting rid of them hard without specialist equipment. DIY methods generally target visible ants and miss the main colony. For better results, reach out to our ant exterminators.
How Many Odorous House Ants Count as an Infestation?
A single odorous house ant colony can include thousands of individuals; seeing more than a few foraging at once should not be ignored. It may indicate an extensive odorous ant infestation is close by. Trails that appear consistently in the same area, particularly near food or water, are usually the first clue.
