How To Get Rid of Ants
Eliminate the Food Source
Ants send out scouts to search for food, the scouts will wander endlessly and there seems to be an endless supply of scouts. Given time, ants will nearly always find any food in your home. Ants may seem disinterested in some foods, but it really depends on what the colony needs. Something ignored this time month may be their food of choice a month later.
To cut off the supply of food, place open foods into tightly sealed containers or store them in your refrigerator. Wipe down counters and sweep floors nightly. Clean cabinets, drawers and shelves to remove crumbs and stains. Ants also need water, so keep sinks and counters dry to discourage them. This is typically only a problem during the hot or dry seasons.
If ants are eating pet food from your pet's bowl, create a moat around the bowl. To do this, place the food bowl into a pie tin or similar low pan and add soapy water to create a barrier around the bowl.
Natural and Less Toxic Control of Ant Colonies
Outside your house, ants favorite food is the honeydew created by a variety of insects such as aphids. By controlling honeydew producing insects and by choosing plants that are not popular with these insects, you will reduce the food supply for ant colonies.
Use of ant baits minimize the use of insecticides and so are preferable to sprays. However, baits can have the undesirable side effect of attracting new ants. Baits include a tasty attractant and a poison. The ants carry it back to the colony and in a few days the colony begins to die off. However, other colonies may send out scouts who discover the bait and then those far away colonies send workers to collect food. So baits are best used by placing them in the path of an ant trail and then remove the bait after the ant activity stops. Baits use different attractants, so if one doesn't work, try another. Also, because ants tastes change depending upon the needs of the colony, a bait that did not work in the past may work now.
Use sticky barriers, such as Tanglefoot, to keep ants from traveling up trees and plants. Prune branches that touch your home, fences or that otherwise create a bridge for ants to cross.
Low toxicity compounds to control ants include boric acid and diatomaceous earth (DE). Other compounds may be equally safe, these are just two examples of natural compounds. Products which contain either of of these are fairly safe for your family and pets. Although, make certain that all other compounds used in the product are also safe. Be sure to read and follow all instructions for the use of any pest control product. Finally, another method of control is to pour boiling hot water into the entrance of a nest. Ants can survive under water, so boiling water is needed to kill them.
