Ants and Schools
On this page:
Basics
Ants are insects of the family formicidae. Like some types of termites, bees and wasps, ants are social insects and live in colonies made up of thousands of members.
Like other insects, ants have:
- Three body segments:
- head;
- thorax; and
- abdomen.
- An exoskeleton.
- Six legs attached to their thorax.
- Two antennae.
Life Cycle
Ants have four life stages:
- eggs;
- larvae;
- pupae;
- adults.
There are three different types of adult ant:
- Workers (also known as soldiers), which are females.
- Males (also known as drones).
- Queens, which are females.
Infestations
Many different types of ants are considered pests including:

- Yellow Crazy Ants.
- The Pharaoh Ant.
- Carpenter Ants.
- Argentine Ants.
- Odorous Ants.
- Red Imported Fire Ants.
Health Concerns
Ants can contaminate food, but most common species in the United States generally do not cause public health hazards. Species of ants that are dangerous to human health include:
- Fire Ants.
- Red Imported Fire Ants.
- Black Imported Fire Ants.
- Southern Fire Ants.
When fire ants bite, they inject formic acid into the skin, which can cause welts and allergic reactions, and results in white pustules that often last several days.
In some cases of severe allergic reaction, fire ant stings can be fatal if not treated.
More information on preventing contact with fire ants.
