The Odorous House Ant, or more commonly known as  "sugar ants” is very tiny; less than 1/16 inch long, it is brown to black in color. It has 12 antennae segments, and only one node (waist),
with an uneven thorax when viewed from the side
They also produce a foul smell like “rotten coconut” when crushed, hence the name.

The Odorous House Ant is also one of the hardest to get under
control, because they are a multi queen ant colony. So when you use a
generic ant spray that has a repellent in it, it will fracture the
colony, and they will set up shop somewhere else in your home. That’s
why when you spray in the kitchen they show up in the bathroom or
bedroom. You’re actually multiplying your problem

Nesting Habits
Indoors, Odorous House Ant nests may be found within wall
voids, in crevices around sinks and cupboards, and near hot water pipes
and heaters. Outside, Odorous House Ant nests are usually established in
shallow, exposed soil beneath brick, board, or stone. Odorous House
Ants are most likely to enter the home in the autumn time or during
rainy weather, when the outdoor sweet food supply is reduced.

Feeding Habits
Odorous House Ants forage both day and night. They prefer
sweet items, including syrup, candy, honey, and sugar, but will also
feed on insects, seeds, and plant secretions. 

Females Odorous House Ants lay at least one egg per day. Once
hatched, it takes about 24 days for the young Odorous House ant to
reach adulthood. Colony size ranges from 100 to 10,000 ants.
