Ants are some of the most common household pests in Texas. Most ant species that invade homes nest outdoors. A few may nest in walls or interior areas of homes. Knowing what species of ant you are dealing with is an important first step in eliminating unwanted ants from your home.

Together with rover ants, pharaoh ants are among the tiniest indoor ants. Light colored, with a dark tail (gaster), Pharaoh ants require special baits for best control.
Crazy ants
Historically, crazy ants have not been considered an especially important group of ants. This changed recently in Texas with the discovery of an exotic species being called the Caribbean or the Rasberry crazy ant. This species of ant has proven to be an extreme pest in parts of about a dozen counties in the Houston, Texas area. Unless you live in one of these infested counties it is unlikely you have this ant. Heavy outdoor ant populations can occur with other ant species, such as Argentine and pyramid ants. So don’t jump to conclusions if you think you’ve been invaded by ants from Mars!
