It is important to note that ants forage from the nest looking for food and water. They mark their routes or trails with pheromones so that they can find their way to the nest from looking for food and water. If you disturb these pheromone trails the ants will not be able to find their way back to the nest and if the foraging ants do not return to the nest then the original nest may bud or split up and the whole life cycle will be sped up to produce more ants and the net result will be that you will have more ants to deal with than what you originally had.
It is important not to spray chemicals on these pheromone trails as this will destroy the pheromone trails and you may only kill some foraging ants but will disturb the whole nest leading to budding. By spraying the foraging worker ants you will only destroy about 5-10% of the colony and you will accomplish very little.
You will see ants foraging, normally following each other in a straight line along a pheromone trail in and out of your house or in your garden.
You will see sand mounds on your lawns or pavements from the ants pushing the sand out of the ground to expand their nests.
In some places you will just see the holes where the ants would move in and out. Depending on certain times of the day the ants might not be active.
Ants make very large nests and normally make their nests right next to your homes; they create damage to pavements, concrete slabs and bricks in your walls while making space to expand their nests.
They will often contaminate your foods mostly sweet things for example sugar. They are not necessarily dirty insects but once the ants get into your food you will have to throw it away because you will not get all the ants out.
The ideal way to control ants is to provide them with baits formulated from proteins and carbohydrates depending on the type of ant species to take down into their nests and to distribute these by food sharing or tropholaxes. In this way you will use the behavior of the ants to get your baits deep into the nest and thereby controlling the ants with the ants themselves.
We combine the bating treatment with a spray treatment once the bait has been taken into the nest and consumed we use a high pressure pump to inject the nest with chemical to kill off any worker ants that did not consume the bait.
