Why you have ants:

Ants feed on sweets, starches, and even greasy foods. They will typically enter a building when foraging for food and water and they can travel long distances. The ants that you find foraging in homes or buildings will account for typically 10% or less of the colony size. When these foragers locate a food source they will lay a scent trail (with pheromones) leading to and from the nest. Once the trail is established, you will have an ant problem. Indoors, they are usually found along walls, hiding under baseboards or carpets. Outdoors they are generally found under decorative landscaping, wood piles or rocks.


General Facts:

So far, there are about 12,000 species of ants known, but only a handful of these species will typically be found infesting building in the Long Island area. Their main habitat are the tropics.

The ants (Formicidae) are an invertebrate family, which belongs to kingdom animals (Animalia), phylumArthropoda, spike Insects (Insecta), order Hymenoptera. Their origin is not very clear. It is supposed that their ancestors is a species of non-social wasps. In the course of time, the animals of this species got specialised. The castes (a group devoted to a specific activity) were formed.

Ants, as well as bees and wasps are social insects. This means that they build a kind of a settlement and live in a society with strict hierarchy. In contrast to bees and wasps, which build their nests out of wax or cellulose, ants are not so dependent on the enviroment and resources. The anthill can be build out of all kind of materials and on all kind of places.

It can be entirely underground (the yellow ants Lasius flavus get on the surface for their nuptial flight only) or partly underground (most species of ants:the black ant Lasius niger and Formica fusca, the big red forest ant Formica rufa), as well as in living or dead trees (the shining-black wood ant Lasius fuliginosus).

The incredible agility and adaptiveness has turned ants to the most successful and numerous species on the planet.
