Odorous House Ant
Tapinoma sessile
The odorous house ant tends to colonize near heat sources and in insulation when indoors and under rocks and exposed soil when outdoors. Colonies can range from 100-10,000 in size, and the longer you wait to take action, the larger the population will get, making it a matter of weeks before the area can be cleared.
