What Kind Of Ants Are In My House

Types of Ants that Live in Houses

It is common to find ants inside a home, especially during the warmer months. Ants become a nuisance when they enter in large numbers, or if they are persistent. Knowing what species of ant has taken up residence in your house can help in determining the best course of action for their removal.

The majority of indoor ants are nuisance species, filling up the meters of observing entomologists and the worries of the house dwellers. They do not sting or pose health threatening threats, but their presence in large numbers is a nuisance. Ants are social insects, so you will find many of them in one location. Some of the most common house ants include the carpenter ant, odorous house ant, and pavement ant. All three can reproduce very quickly, so numbers can rapidly increase if not controlled.

The carpenter ant is the largest of the three, measuring up to half an inch long. These ants will build their nests in wood and if left uncontrolled their nesting activity can cause significant damage. Odorous house ants are far smaller, ranging between one to two millimetres in length. As their name suggests, they give off a peculiar odour when squashed, which is why they are frequently referred to as ‘stinky ants’. Unlike the carpenter ant, odorous house ants won’t cause damage to structures, as they use other ants’ nesting galleries, but they can contaminate food. Pavement ants are the smallest, measuring up to just three millimetres long. Found near pavement cracks, these ants are considered to be an outdoor species, however they will travel inside if a food source is found.

When dealing with house ants, the best option for control is to use a baiting system. This is effective for larger infestations as the ants are attracted to the bait and will carry it back to the nest. Contact insecticides can also be used, but this requires you to know where the nest is located in order to treat the area. To help with identification and locating the source of an infestation, it’s best to consult a professional pest controller.

Prevention is Key

The best way to protect your house from becoming the new home of ants is prevention. Ants are attracted to food, water and nesting materials, so it’s important to keep these away from your house. Exclusion measures should be taken in order to prevent them from entering in the first place. For example, sealing cracks and crevices, or adding a weather strip to your external door. If a food source such as rubbish and pet food is present, this too should be kept away from external walls and other potential entry points.

Ants can be difficult to control, and if left unmanaged their numbers can increase rapidly. It’s important to identify the species of ant that is causing the infestation and use the correct methods for its removal. If you’re unsure as to what species of ant is living in your house, or require assistance, it’s best to consult with a professional pest controller, as they are equipped with the knowledge and experience to identify the species and carry out appropriate pest control operations.

The Role of the Ant in Nature

Despite the fact that these ants are still considered a nuisance, they are an important part of their local environment. Ants provide vital ecological roles including seed dispersal, soil aeration, and controlling pest populations. With over 12,000 species of ant worldwide, it’s no surprise that their role in the environment is diverse.

For example, some species are known for their ability to disperse seeds with their foraging activities and help promote plant growth. Other species have a symbiotic relationship with aphids and scale insects, another type of pest. Ants will feed off the honeydew produced by these insects, which in turn keeps them under control.

The most important role of an ant species though, is in maintaining balance in an ecosystem by regulating animal numbers. Ants are a popular food source for many other species, providing a protein enriched diet. Knowing the importance of ants in an ecosystem, it’s best to find a balance between controlling their numbers and allowing them to thrive.

The Benefits of Having Ants

Surprisingly, there are benefits to having ants around your house and garden. They perform many vital functions for the environment, including scavenging, aerating and fertilising soil, as well as being a food source for animals. In addition, some species of ant are beneficial for organic agriculture by using their nesting and foraging behaviour to protect certain plants.

Ants also act as natural pest controllers. There are various species of predatory ant that will actively hunt and consume other pests, such as aphids, caterpillars and even other ants. This offers control of pest populations with no use of chemical pesticides and helps minimise the risk of non-targeted species being affected.

Where do Ants Fit in Your Life?

The presence of ants inside a home is almost unavoidable. They are everywhere and can be difficult to eliminate. Taking into consideration their ecological importance and the fact that they are active controllers of pest populations, it’s best to find a balance between controlling their numbers and allowing them to thrive.

The best approach is to prevent them from entering the house in the first place. Exclusion methods can be applied such as sealing cracks and crevices or weather-stripping external doors. However, if ants have already found their way inside, using a baiting system or contact insecticide is the best approach for their removal.

Conclusion

Generally, house ants are not dangerous or fatal, but they can become problematic in large numbers. It is important to identify the species of ant causing the infestation, as the appropriate control method will depend on this. A professional pest controller may be needed to assist with identification and the most suitable control method.

Though ants can be a nuisance, they do provide an important ecological role. Therefore, it’s best to find a balance between controlling their numbers and allowing them to thrive. Prevention is the best method of protection, however if they are already inside, the best approach is to use a baiting system or contact insecticide.
