You can choose which products suits your particular problem or call us for advice.

Here is some information and advice about dealing with an ant infestation.

Ant Basics - About Ants

There is one main Ant species that causes the most infestation issues in the UK, the Black Garden Ant (Lasius niger).

There are many other types of ants and it is fairly important to identify the type of ant you are dealing with in order to be able to resolve the problem.

Most people recognise the Common Black Garden Ant, but ants such as the Pharoah's Ant will be much harder to identify and you may need to seek our help for anything other than the Black Garden Ant.

Incidentally, this ant does not restrict itself to the garden and is a major indoor pest, seeking food from your home, often, high sugar or protein content foods but any human food may attract an army of these little pests. It is very rare for this ant to nest indoors!

Most ant colonies have a queen, the queen stays in the nest, which in the case of the Black Garden Ant is generally located underground. You need to kill the queen in order to achieve total eradication of an ant problem and please consider that there could be more than one nest!

The queen ant lays many thousands of eggs during her extensive lifetime (up to 30years!)

Flying ants are mainly fertile female ants, bred in the nest in early spring, that leave the nests in May or June and fly high and spread to form new nests. Further information in the next section below.

Evaluation and preparation for treatment

Before commencing the treatment is is important to find where the Ant nest is located, if that is possible, as the closer to an ants nest the treatment is trageted the more successful it will be.

If the ants are inside the house and they are the black ant, follow their route source until it enters the structure of the building, ie: under the kitchen sink, then look outside the house in that immediate area to check if they are visibly evident outside, if so, keep following the route until it enters the ground. The nest should be near this point.

If there is no evidence of an ant run outdoors then your ant control treatment will need to be carried out mainly indoors.

If your treatment is going to be an indoor one using an ant killer spray,Pro-Active C for Ants remove any uncovered foods and unprotected eating/cooking utensils from the treatment area.

If your treatment involves outdoor spraying, then move any pots or loose garden ornaments to 2 metres away from your treatment area to enable complete ant killer insecticide application.

Most ants nest outdoors. To keep them from migrating indoors, a little preventative maintenance is necessary. If your home is prone to ant infestation, spray an insecticide formulated specifically for outdoor ant removal around the outside perimeter of your house and include to spray any wall air vents and around window and door frames.Dethlac Ant Killer Aerosol

Dethlac will stain UPVC framework so please be careful not to apply to plastic window and door framing. Dethlac is a laquer that will give extended ant killing capability.


Flying ants are usually a problem on hot days in May or June. Outdoors they are not something you can treat but indoors you may want to use a normal fly killer aerosol spray or insecticidal smoke generator.

Opening windows can resolve the problem as the flying ants actually desire to get into the air at high levels, so if they accidentally get into your home, releasing them is the easiest and greenest solution.

Try to find the access point and seal.

Effecting the Ant Control treatment

Maxforce LN Ant Killer Bait Station

Having searched carefully you are now ready to tackle the ant problem. We strongly recommend the use of Maxforce Ant Bait Stations, which are small plastic receptacles containing a gel which will be eaten by some ants and carried to feed the larvae and queen by other ants.

This bait can take one or two days to work as it is purposefully slow acting to allow the ants to carry it back to the nest and feed the ant larvae and hopefully the queen too. These can be used indoors and outdoors and we suggest two bait stations per nest of ants.

If you prefer a more rapid result, then we suggest our Pro-Active C Ant Killer spray, which is applied to all the areas where the ants are know to be moving.

This product, once applied and dry, will kill within hours of contact with the ants. It can be used inside the house and is safe to children and animals once dry.

Pro-Active C Ant Killer Trigger Spray

When treating near or alont the back of kitchen worktops, wipe down food prep areas with a damp disposable cloth/paper towel after the treatment and perhaps leave a small band of insecticide along the back of the work top.

Remove any live fish, or animals from the room being treated and return them after 4 hours.

We also suggest keeping children out of the treatment area for the same period of time.

Should the ants be active in the garden, particularly on lawns, then we suggest the use of Ant-Stop granules which can be applied either directly onto the nest area or diluted in water and applied to the ants nesting area.

Ant Stop Ant Killer Granules

As most insecticides are now banned for use on the soil, this product fills a gap in the market for ant control in lawns and soil.

These granules are effective to kill a wide range of ant species including red ants.
