Solenopsis
molesta
Characteristics –
Size: One of the smallest ants found infesting buildings,
measuring less than 1/16-inch in length.
Color: Golden-yellow
Because of the thief ant's size and color, it is often confused with
the pharaoh ant which is a bit larger. Thief ants have only 10
segments in their antenna and the antennae end in a two-segmented
club. Pharaoh ants have 12 antennal segments and a three-segmented
club.
Behavior –
Thief ants derive their name from their habit of locating their
colonies close to those of other ants to steal that ant's food and
even capture and eat the other ant's eggs and larvae. Colonies are
usually small and are difficult to find. In homes, trails are often
seen in bathrooms and kitchens and in and around windows where the
ants can find moisture and food.
Habitat – This ant will nest in soil, in wood,
in voids, and in just about any suitable location. Finding the nests
is extremely difficult.
Tips for Control – Thief ants can be difficult
to control. Often they are mistaken for Pharaoh ants; unfortunately,
the baits used to control that ant may not be effective for thief
ants. Thief ants tend to prefer foods with higher protein and fat
content. The experience of a professional with access to a number of
different ant baits is likely to achieve better results
