These tiny ants – only around 2mm long – are an unusual light brown to yellow colour with the abdomen being a little darker. Their antenna is also unusual in that it ends in a club like a shape.
Signs of Infestation
An infestation is noted by seeing the ants march along your surfaces or floors looking for food sources. They have a very varied diet but particularly seek sweet things. They are so small that they can gain entry to your property through even the smallest of cracks.
Pharaoh ants use pheromones for various communication messages, from recruitment to mating calls. They effectively use them to track their food trails, marking both positive and unworthy trails with different pheromones.
Pharaoh ants can reproduce within 38 days with worker ants living nine weeks or so. The queen lives for around 12 months and continues reproducing either in the current colony or breaking off to form a new one if the colony becomes too large or is deemed at risk. There are several queens in each colony.
These ants are unusual in that they do not swarm (which is the more common mating method of ants where they take to the sky to mate). Pharaoh ants mate within their own nest.
Call the professionals
Dealing with these ants incorrectly can actually worsen the issue as they may split their colonies to new areas to escape the pesticides – so now you have multiple colonies instead of just one! The Pharaoh Ant is considered by professionals to be one of the most difficult insects to eliminate.
