West Lothian Council provides a service for the treatment of garden ants in properties.


Garden Ants are harmless, however, they can reach high numbers in a property where they have access to a food source. They in general are coming into your home from outside.  The first thing to do when you find Garden Ants in your house is to carry out a thorough clean of affected areas prior to calling out the pest control service.

What does it cost?

Garden Ant treatment costs for non-council houses are:-

£170.91 (incl VAT) for a complete treatment (a maximum of 5 visits),

£85.46 (incl VAT) for a full treatment (a maximum of 5 visits) for those entitled to any concession.

Non domestic properties are charged at £170.91 (incl VAT) for the initial visit then £71.94 (Excl VAT) per hour or part thereof for each subsequent visit.

How quickly will we attend?

We aim to attend calls within 5 working days.

Do I have to do anything before the officer comes out?

There are a number of actions you must take before the pest control officer attends to ensure the treatment is effective in the quickest possible time.

  • Thoroughly clean the area where most Garden Ants are seen regularly.
  • Do NOT use any insecticide at any point

What are our working hours?

For the initial visit, we offer a choice of either 08:00 - 12:00 or 12:00 - 16:00 Monday to Friday.  After the initial visit, if required, you may agree a revisit with the officer attending outwith these hours but we cannot guarantee this will be possible.

We do not work over the weekends or on public holidays.

How long does a treatment take?

Garden Ant treatments may take more than one visit.  The insecticide used is usually as a bait and we require the ants to carry them back to the nest to be effective.  For this reason it is important NOT to use any other insecticide such as ant powder as this will mean our treatment will be ineffective.  The ant powders have a good effect for a short time but without our treatment the problem is likely to recur.

After treatment you may observe ants and larvae for a short time as there is no treatment which will kill off either the eggs or pupae and they have to be allowed to hatch for the insecticide to have an effect.

Do you carry out any works to stop future infestations?

No.  There is no way to ensure you will not get Garden Ants in future years although maintaining a high level of hygiene will ensure that any infestation is kept low.
