Ants
The common garden/black ant is common in the UK. It is seldom considered a pest until found in your home nesting or penetrating property from the outside.
Mid Wales and Borders Pest Control will conduct an initial survey and advise treatment appropriate treatment.
Insecticide gel can be placed in cracks and crevices both indoors and outside. With correct placement this can gain quick control of the infestation.
In the case of penetration to a property, proofing with cement/mortar or mastic will be required. Insecticide dust or spray will also be applied to likely access areas to provide residual protection.
