What do you know about ants? – Laval News

Species known to invade homes in Canada include the carpenter ant, the little black ant, the odorous house ant, the thief ant, and the pharaoh ant. While some of them can sting, most of them are not aggressive. However, carpenter antsare well known for their ability to damage wooden structures and they can become a nuisance.

Ants are tiny insects and may be black, brown, red, or yellow. Adult ants range in size from as small as 1 millimetre (1/16 to 1/32 inch), like little black ants and thief ants, to as large as 13 millimetres (1/2 inch), like carpenter ants.

Most ants commonly found in Canada are not aggressive, although some can sting. Ants should be tolerated as much as possible since they cause little damage in the garden. They can even be considered beneficial because they eat other insects like young silverfish and moths.

Species known to invade homes in Canada include the carpenter ant, the little black ant, the odorous house ant, the thief ant, and the pharaoh ant. Pavement ants can become a nuisance in lawns, gardens, and pathways, as well as indoors.

Carpenter ants are larger than other species, although the sizes of the workers vary. They can cause structural damage to homes as they destroy wood to make room for their nests. Piles of sawdust may mean you have carpenter ants.

Ant colonies send out scouts to search for food. Ants are attracted to many types of food. They enjoy eating sugary and greasy foods (like peanut butter or crumbs) and are also attracted to the honeydew produced by aphids on infested houseplants. A successful scout leaves a scented trail for other workers to follow back to the food source.

Removing access to food and water is the easiest way to avoid pest problems:

If you use a pesticide to control your pest problem, read the label to make sure you are choosing the right product for the right pest. Follow all label directions and warnings carefully. Always look for a Pest Control Products (PCP) number on the label so you know the product has been approved by Health Canada. See Use pesticides safely for more information on using pesticides safely.

Many chemical products can be used by consumers to control ants:

Some provinces and municipalities have placed more restrictions on the use of certain approved lawn and garden pesticides. Please check with your city, province, or local lawn care centre for more information.

Bait systems

Ants gather food and bring it back to the nest to feed ant colony members. So a bait system must work slowly enough to allow the poison to be fed to all members of the nest. This is a highly effective way of getting rid of nests. Baits containing boric acid are generally of low toxicity to other animals.

The red carpenter ant and the black carpenter ant are two of the most common types found in Canada. The red carpenter ant has a dark brownish-black body, with a reddish-brown upper body. The black carpenter ant is dark brownish-black all over.

Carpenter ants are from 6 to 25 mm (.24 to 1 inch) long. A carpenter ants body is divided into three segments, with a very slim waist separating the upper body and lower body. Their antennae are bent and in sections. Male and female adults have wings at mating time.

Carpenter ants are well known for their ability to damage wooden structures. They are also a nuisance in homes as they search for food. Carpenter ants eat both plant and animal matter. Their natural food sources are insects, other small invertebrates, and sweet body fluids from aphids and other insects. Protein and sweet foods found in and around homes also provide food for foraging workers.

Carpenter ants build nests by burrowing into wood. They dig tunnels (called galleries) much longer than those created by termites. The wood is not eaten, but thrown from the nest as sawdust-like shavings.

Carpenter ants are sometimes confused with termites, but it is easy to tell the difference between them. The termite has straight antennae and a thick waist, and the carpenter ant has a very narrow waist and elbowed (bent) antennae. Termites are found only in certain areas in Canada.

Carpenter ants live in large colonies with hundreds of workers (all sterile females), several males and females that reproduce, and one or more queen. When part of an established colony goes into a nearby structure, it sometimes establishes a smaller satellite colony there. Some experts believe this is the main way carpenter ants invade houses.

Outdoors, carpenter ants are found in dead trunks of standing trees, stumps, or logs, or under fallen logs and stones. They can sometimes mine sound wood, but they usually choose a soft type, like pine.

Indoors, because they prefer moist, decaying wood, carpenter ants can signal a moisture problem, or wooden structures that are decaying. As well as tunnelling in the trim of buildings, wooden steps, and window sills, ant colonies can nest in houses without attacking structural timbers, using hollow spaces like wall voids, attic spaces, and hollow doors. They can even be found behind books in libraries, behind drawers in dressers and cabinets, and in styrofoam insulation.

Carpenter ants get into houses by several ways:

If you use a pesticide to control your pest problem, read the label to make sure you are choosing the right product for the right pest. Follow all label directions and warnings carefully. Always look for a Pest Control Products (PCP) number on the label so you know the product has been approved by Health Canada.

Chemicals can help you eliminate existing nests and prevent new nests from forming. Chemical control works best when you use it along with physical control.

Once a colony is well established, you usually need to locate and treat the actual nest site for permanent or long-term control. In the case of a satellite colony, the parent colony should be located and destroyed for most effective control. In difficult situations, use a professional exterminator.

Various pesticide products for are available for homeowners, and can help reduce the number of ants infesting your house. If you plan to do an indoor application, check the product label to make sure it is registered for use inside your home. There are also several other commercial products available to professional pest control operators.

For commercial food processing or preparation, use products specifically labelled for these areas. Carefully follow all label directions and warnings. Remove or cover all food, packaging material, and utensils before treatment. Afterwards, wash all surfaces that may be in contact with food and rinse thoroughly with water before re-use.

Please note: When applying pesticides, you should leave any dead ant bodies where they are. Other scavenging ants will either eat or bring the dead ant back to the nest to feed the rest of the colony. In this way, the pesticides effect is passed on.
