PestXpert Nest Kill Ant Bait

PestXpert Nest Kill Ant Bait is a new type of ant control product for controlling ants outdoors. Using a combination of the latest ant control technologies, Nest Kill Ant Bait is designed to make ant control easy for home owners.

Many homeowners struggle to get on top of ant problems. To get lasting control of ants, you need to kill the queen ant. Using insecticide sprays can kill a lot of the worker ants but they don't kill the queen, As a result, the queen, hidden in the nest, continues laying eggs and the problem returns.

It is often very difficult or impossible to find the nest, so we need a smarter way to target the queen. The answer - ant baits. Ant baits tap into normal ant foraging behaviour to get the insecticide back to the nest to kill the queen.

PestXpert Nest Kill Ant Bait is a combination of irresistible "ant food" and slow acting insecticide. Worker ants take the bait back to the nest, feeding it to the queen and other nest mates. The bait is passed throughout the nest before they realise something is wrong, resulting in  colony elimination.

With baits, you don't necessarily have to find the nest to control the ants. As long as you place the bait where the ants are active, they will do all the hard work for you.

Nest treatment: If you are lucky enough to find the nest, place a small pile of bait by each nest entrance or sprinkle the bait over the nest mound. It is a bit difficult to determine how much bait to apply but normally enough bait to last 30 minutes is sufficient. Start by placing a small amount of bait. If that gets taken in a couple of minutes place some more bait. Continue topping up the bait until they have been taking bait for 20-30 minutes.

Trail treatment: If you have a strong foraging trail, then you can concentrate the bait application along the trail. The best bet is to place the bait in 3 to 5 small piles next to the trail. Make sure a little of the bait actually crosses the trail as sometime they can walk straight past the bait. This can sometimes happen as they are already on a trail going to a different food source and it can be difficult to "change their mind."

Lawn treatment: Sprinkle bait evenly over the lawn or area where the ants are active. The recommended dose is between 20 - 40g per 100m2.

How quickly does PestXpert Nest Kill ant bait work?

After a treatment with PestXpert Nest Kill ant bait, you will typically start to see dead ants after a few days, with most colony elimination occurring after 1-2 weeks, although larger nests may take a bit longer.

However, the speed and completeness of performance depends on the ant species, the size of the nest and how much bait has been applied.

Nest kill ant bait is designed to work slowly (it won’t kill the nest in a couple of days). It is based on the principle that the bait is taken back to the nest and spread around the colony killing the queen and all the larvae and ants in the nest. To make sure all the ants get some bait, you need to provide enough bait for the size of nest. Use the guide above to make sure you apply a quantity of bait that requires the 20-30 minutes of active foraging by the ants to take all the bait back to the nest.

Even though this is a good guide, the difficulty is that you still don’t really know how big the nest is and indeed some species have more than one nest as part of the same colony. If the ants are still active after 4 weeks, it is likely that the nest did not receive a big enough dose. Carry out a second application.


  • PestXpert Nest Kill Ant Bait should be applied in the early spring or summer at the first sign of ant activity.
  • Application is most effective when ants are actively foraging.
  • Wet bait goes soggy and is not very attractive to the ants. Avoid application if rain is expected within 6 hours. DO NOT water treated areas for at least 24 hours after application.

PestXpert Nest Kill Ant Bait works on a broad range of ant species. However, it does not appeal to all species and sometimes ants may just prefer something else (a bit like you!). Before carrying out an application it is best to place a small amount of bait where the ants are active or near a foraging trail to see whether they take the bait. If they do, you're good to carry out a treatment.

Can I use Nest Kill around My veggie patch?

The product is not registered for in cropping areas, as when product is spread from machinery it is less accurate and there is the danger than the bait granules may get caught in the foliage and accidentally ingested (even though the chances of this are low).

However, for the homeowner wanting to protect their fruit and vegetable patch from ants, it is still possible to use PestXpert Nest Kill ant bait, as application can be more accurate. Using the pour spout for extra precision, there are two application options;

  1. Apply the bait to the ground around the perimeter of the vegetable patch. This is particularly useful for densely planted areas
  2. Apply the bait to the ground between rows or at the base of plants

Avoid getting any bait caught in the foliage of the plants

Extra tip: As ants often appear on plants to tend sap-sucking insects such as aphids and scale insects, application of a suitable insecticide registered for the control of these sucking insects will make the plants less attractive to ants.

Safety tips
