Ants generally become a problem in houses and other buildings when their nests have become disturbed by rain, or conversely, during dry weather to look for water, or a nesting place.  Poor hygiene and and pet bowls also draw them indoors.

Outside conditions such as sandy areas, pavers and garden pots also are favorable conditions for ants. Major colonies may be found under insulation batts in the roof and in the wall cavities


Control methods

• Thorough inspection is required before any treatment is carried out
• All entry points should be checked including cracks and crevices in and around the kitchen, bathroom, and laundry areas
• An inspection should also be carried out for nests in the garden, under the subfloor and fencing
• Improving housekeeping and sanitation levels within the site
• The use of pesticides in the form of liquids, gels, dusts and gasses
