Ant Killer Sprays

Ant barrier sprays are designed to stop ants and other insects crossing a threshold such as a door step or window frame, ventilators, ducts and drains. Pay particular attention to areas where pipes enter the building such as under kitchen sinks. Barrier Sprays work by laying a residual (long-term, in the case of Dethlac up to about three months depending on conditions) band of insecticide across the route that the insects use to access the building.

Ant residual sprays can be used where long-term protection is not needed as the aim is simply to eliminate the offending colony. These sprays may be effective for around two weeks or considerably less if exposed to weather. They can be used in and around the nest and foraging area. The spray lays down a fine film of insecticide and when the ant contacts the insecticide and subsequently cleans itself, it ingests the product and dies. A potential weakness of some of these sprays is that they contain an ingredient (Pyrethrins) that may repel ants before the whole colony has become contaminated.

Ant Killer Powders

Ant powders are perfect for dusting into dry but hard to access areas such as under floor boards, behind skirtings, into cracks and crevices, under cupboards and other areas where ants may be hiding. As long as it the powder is kept dry it can remain active for many months, making it a perfect long term solution.

Ant Bait Stations

Using bait stations is the best way to eliminate a whole colony but a little patience is required. Bait stations rely on the previously mentioned habit of ants to inform the colony of potential food sources. Two or more bait stations should be placed in the area ants are seen foraging for food. An ant will find the bait station and take some bait back to the colony. Because the bait has been carefully formulated to be attractive to black ants, the whole colony will soon start to feed (or be fed) on the bait.

The active ingredient within the bait is slow acting so by the time the whole colony have sampled the bait it is too late and they will all have consumed a lethal dose. The whole colony should be eliminated within a couple of weeks. Make sure that you have enough bait stations to feed the whole colony.

The black garden ant is found throughout Britain and is one of only a very few garden nesting ants that are commonly found foraging in our homes. Black ants frequently nest under stones, paving slabs and door steps close to houses. From there they forage widely and soon find their way into domestic premises in search of their favourite sweet foods.

The Common Black Garden Ant is the species most likely to be encountered by the British householder. It can easily be identified by its black colour (most of the other ants you are likely to see will be red or orange, except for the black wood ant). Learn more about the different types of ants.

Ants are able to enter through the smallest of cracks making physical proofing difficult. First try to identify where the nest is located. It may be under the doorstep, under footpath flagstones, inside the house under the floor boards, in the cavity wall and so on.

Potential food sources should be contained within sealed packaging. Make sure that all obvious access points such as gaps in skirting boards, cracks in floors and walls are sealed with a suitable sealant. However, insecticidal barriers are the most effective.
