Pharaoh Ants

The Pharaoh ant is a small ant, measuring from 1/16th to 1/12th an inch in size. The workers are all one size (monomorphic). The Pharaoh ants colour varies from golden yellow to reddish. Pharaoh ants originated in and derive from the tropics, meaning they can`t survive outside in the East Coast year-round.


Females mate and procreate in the nest, and new colonies are formed by “budding.” Budding means that part of the main colony moves to a new location, and there can be up to hundreds of thousands of ants in one colony.

A female produces 350-400 eggs in her lifetime. The entire life cycle is completed in 38 to 45 days. The life span of workers is approximately nine to ten weeks, and queens live four to twelve months.


Pharaoh ants nest in a wide variety of locations within a structure and are very difficult to control and locate. However, it is useful to look near sources of water and food. They typically nest in warm, hard to reach areas such as walls, splash boards of kitchen countertops and in wall sockets.

Pharaoh ants prefer meats or greases, but will also feed on sugar syrups and jellies.


Pharaoh ants must be treated by using protein and sugar baits placed as close as possible to the nest areas. It is very important not to use any insecticide sprays or dusts as this will stress the colony – causing it to split and spread, and aggravating the problem.

Carpenter Ants

Carpenter ants are the largest of all ant species, ranging from 1/8 to ½ inch long, with slightly larger sized queens. Carpenter ants are typically black in colour, but some species can be found in red and black, solid red, or brown.


Adult winged females lose their wings soon after mating, and all worker carpenter ants are wingless. Mature colonies range in size from several thousand workers, up to 10,000 – 15,000. Black carpenter ants complete their life cycle in roughly 60 days.


Carpenter ants are social insects that are usually discovered nesting in wood. Carpenter ants do not eat wood but do excavate galleries for their nesting areas. Carpenter ants actively feed at night and the early morning hours, preferring to feed on sugar solutions.


It is recommended that any decaying or piles of wood should be removed from the property. All food items should be stored in sealed containers. Any food spills should be cleaned up immediately. Because it is a difficult task to locate and provide treatment for carpenter ants, it is recommended to contact a pest control company to assist in eliminating this problem.
