Why Should Ants Be Treated?

Worker ants will frequently enter dwellings foraging for food, particularly sweet substances. While not a risk to human health, they can be present in sufficient numbers to cause a nuisance. The ants will almost certainly be coming from several nests so locating one nest and destroying that will have a limited effect.


Prior to treatment, the affected areas should be cleaned, any cupboards emptied and toys, pets, etc. removed from the area. Insecticides work more effectively on clean dust-free surfaces.


We treat the infested and surrounding areas with one (or all) of the following insecticide sprays: Effect Microtech CS’* which contains Permethrin, HSE Number 6287 and made by Sorex, Ficam w which contains the insecticide Bendiocarb or K-Othrine WG250, HSE Number 5390 which contains deltamethrin 25%. As well or instead of these baits may have been used. These will be either Digrain Ant Gel and is made by Lodi and contains Permethrin or Advion Ant Gel which contains Indoxacarb. These insecticides are the most modern insecticide available. Ficam may also be used in a powder formulation called Ficam D*. All insecticides are biodegradable, almost odourless, non-tainting and do not corrode or stain.

The outside, as well as inside areas, would have been sprayed as the nests are usually outside but the insects may swarm or forage for food inside. A band of insecticide has been sprayed around windows, doors and walls to keep them out. The ants walk over the treated areas and return to the nest touching other ants and larvae with their contaminated bodies which pass on enough insecticide to kill the nest(s). This may take up to 2 weeks (if treatment is carried out before April or in cold weather the activity may continue sporadically for up to 6 weeks), immediate improvement is always noticeable but do not wash down or vacuum treated areas for at least 2 months. Washing and vacuuming will break down the insecticides. The baits work in a similar fashion but may take slightly longer to work.

What Do I Do Afterwards?

Do not wash down or vacuum treated areas for at least 2 months. The insecticide will slowly degrade but will break down straight away if you wash or vacuum treated surfaces. Immediately after treatment let the spray dry, do not clean or wipe up any puddles, if you touch the treated surface while still wet then wash off, do not let animals on the treated areas until dry.

Flying Ants are the Queens and Drones that the workers have pushed out to start new nests for the following year, although the original nest may last several years. Occasionally Ants will swarm after treatment (usually late Summer), this will quickly die down as swarming ants come into contact with treated surfaces. The treatment is designed to keep ants out from inside areas. If the bait only option has been used then it is vital that workers are not disturbed. There will even be a burst of activity before the problem subsides. The workers must not be killed but allowed to return to the nest to carry the poison back to the nest to do its job.


This treatment is guaranteed (inside treated areas only) for one month after the first treatment and is only valid as long instructions and advice on hygiene and other matters are adhered to. Insecticide treatments will only work on clean surfaces. PEST UK’s Terms & Conditions apply.
