Ants Thrive in Perth

In the Perth area ants are completely at home thanks to the plentiful amounts of dead, wet wood… the kind of material in which ants like to make their homes. Tree stumps and old, rotting logs are perfect spots for nests, and so are building structures where moisture has been allowed to begin the process of decay that ants find so appealing.

Carpenter-Ant-Damage-300x234Damp wood in a home as a result of leaks from poor construction, damage to the structure, or poor maintenance is the perfect habitat for ants, which are constantly on the lookout for places to raise their young. To get to either, they burrow their way through the damaged wood, and eventually chew through newer, drier wood to get from place to place. In the process, they weaken the wood structure, which could eventually cause it to require significant repairs that will be expensive. In the absolute worst-case scenarios, the building could eventually collapse from the damage, although the likelihood is extremely minimal.

Wood decay may be caused by exposure to leaks, condensation or poor air circulation. Nests in homes are usually found behind bathroom tiles or around sinks, tubs and showers. Floors under leaking dishwashers create ideal conditions, as do leaks under roofing and in attic beams, or under sub-floor insulation. Hollow spaces such as doors and wall voids are good, and even foam insulation is often used. Ants will establish satellite nests and not all nests require damp wood. Foam insulation is easy for an ant to chew through and construct it’s maze of tunnels.

How to prevent carpet ants from coming near your home

The best way to avoid damage caused by carpenter ants is to keep your home in good repair, and to prevent opportunities for moisture to rot the wood around the building. This is always a challenge in Metro Perth, but the good news is ants will not start an assault on your home by attacking dry wood although they will set up satellite nests in dry wood or Styrofoam insulation. The best defense is ensuring that any opportunities for moisture to do damage are minimized.

Extra Tips

  • Make sure your gutters are cleaned regularly to prevent overflow.
  • Ensure the wood siding of your home is not touching the moist earth around it.
  • Don’t pile firewood near the house or let branches from trees touch the building.
  • Remove all stumps and logs from nearby, and check for rotting landscape ties.
  • Ventilate cool, damp areas of your home so moisture doesn’t have a chance to rot the wood from the interior.
  • Make sure you repair all plumbing leaks as soon as they’re spotted.
  • Finally, don’t forget to plug up potential entry points, such as utility line holes, cracks in the siding or concrete, and anywhere else that might provide ready access (this said, they are small insects so do not worry yourself too much in regards to access)

Carpenter-Ant-Queen-300x239Another way to prevent ants from coming near your home is to give them no excuse to do so. Ants love sweet stuff, and have a real knack for finding it. Clematis vines are really nice when they flower in the summer time but they provide a favourite tasty treat for ants, high in carbohydrates. We do not suggest you dig up the whole garden, plants and insects are very important! However, to keep insects such as ants at a distance from your home, you should also keep the food sources a short distance from the home – even if it just means the vegetation is not in direct contact with the foundation or siding.

If you begin to notice lots of ants around your home, and you’re wondering whether they’re going to be a problem to the building, the first step is to identify whether they’re ants or another less destructive cousin. In Metro Perth there are two main species of ant, the all-black Camponotus modoc, and the reddish-brown and black Camponotus vicinus. Ant are larger than sidewalk ants, growing up to half an inch long. The queen ant is easily identifiable because she is bigger – up to almost an inch long.

How they work

carpenter-antThe worker ants are tireless, and are constantly working on building nests or foraging for food. They’re the ones you see traipsing across your floorboards or driveway, and they’re the ones that will chew their way through your house’s wood structure. It’s interesting to note that unlike termites, carpenter ants don’t actually eat the wood as they’re not able to digest cellulose; instead they prefer dead insects, honeydew from aphids, plant secretions, and even rotting fruit.

Carpenter ants in the Metro Perth region are generally most active between April and October (although they can groggily appear as early as late January), and the ant trails (the routes used to travel to food sources) are used most often after sunset and through the night, although ants can be seen on the trails at all hours of the day.

The tunnels created by carpenter ants often can’t be seen because the activity takes place inside of the wood, but if you suspect there are ants in a particular piece of wood, tap it and then listen for the tell-tale rustling sounds you can often hear if you listen hard enough – kind of a “snap crackle pop” (Rice Crispies) Oh, and if you see large, winged ants crawling out of the wood on your home, it’s as sure a sign as you can get that the ants have set up a nest.

Another important tell to determine whether you have carpenter ants or termites is to have a look at the tunnels in the wood. If there’s mud or dirt in the tunnels, it means you have termites, because carpenter ants like tidy passageways.

Carpenter ant colonies build a primary nest – where they lay the eggs – and satellite nests. When conditions are right – normally warm and humid – winged females and males will take flight and perform a nuptial dance. Once the mating has concluded, the males die and the new queens drop their wings and look for moist wood in which to begin a new nest. Then they lay their eggs and the cycle of colony building begins anew.

The primary nest is where the queen sets up shop, and this nest must be kept fairly moist for the eggs to survive. A primary nest can have many satellite nests, and these are the ones typically found in homes because the moisture level doesn’t have to be as great, so more mature younger ants can still survive.

How to Eliminate a Colony

In order to eradicate a colony, the primary nest must be detected and destroyed. You can attempt to do this yourself, or hire an expert in Perth, WA who knows exactly what to look for, and how to track the nest. It’s not always easy to track the ants back to their nest because they’re usually most active at night, so patience will be your biggest asset once you know what to look for.

Oh, and be careful once you’ve found the nest as carpenter ants can, and will, bite humans if necessary. Biting is a defensive measure, and will only occur if the ants feel their nest and offspring are threatened. The bite can be painful, especially when combined with the formic acid they can spray into the wound to cause a burning sensation. It won’t kill you, but it can really hurt, especially if you end up with more than one bite. If you do happen to be bitten, wash the wounds with soap and water, then apply a topical antibiotic cream.

Eliminating ants in Perth and elsewhere requires pretty much the same strategy. You have to go after the queen, the eggs and the larvae or chances are good you’ll simply exacerbate the problem.

One place to start is to eliminate food sources for carpenter ants, in particular aphids. However, the carpenter ant’s “sweet tooth” will take it long distances to find aphids, giant whitefly and scales, so it’s not a highly effective means of control.

There are many products available on the market for eliminating ant colonies; naturally some are more effective than others, and how you tackle the problem will depend on whether you know where the nest is or not. Some products are only effective if they can be directly injected into the nest, while others can be applied externally so that the ants can carry them into the nest. Either way, the poison must get to the queen and larvae to be truly effective.

Spraying with insecticides or repellants isn’t the most useful way to go as sprayed-on insecticides will only kill the carpenter ants that are exposed to the killing agent, and while you may kill a bunch of them, you actually risk having the queen go into egg-laying overdrive to repopulate the colony, which could well make the original problem bigger than it was. As well, ants can sense most of the chemical repellants, so they simply learn to avoid the deadly toxins. If the spray comes too near the nest, the workers will simply move the eggs to a new location.

In order to eliminate a nest, therefore, it is best to apply non-repellent borates into the wall cavities that will kill the carpenter ants within seven to 14 days after contact. The non-repellant borates work because the ants can’t detect them, and so carry the chemicals back into the nest to spread their toxicity around. If the wall cavities surrounding the nest have all been injected, then a more toxic treatment can be applied, targeting the nest location(s) only.

Industry experts agree that most over-the-counter options available at your local hardware store are not strong enough to be effective, as their potency is not nearly as harsh as professional-grade products.

Many of the most effective products require a trained technician who is a licensed applicator. Proper care and handling is essential, as some of the most toxic chemicals used to eliminate carpenter ants are also toxic to humans. If you do plan to use retail products, read the instructions carefully and follow all directions exactly. Also, be sure to check whether the product is specifically meant for carpenter ants, as not all ant-killing products are up to the challenge.

To properly and effectively tackle an infestation of carpenter ants, a professional pest control program in Perth is the way to go, and your local pest management company is best able to tackle the problem for you with the right expertise, techniques and product lines. It’s important to note that eliminating a carpenter ant colony takes time, and might require more than one visit by a professional exterminator.
