If ants have started appearing throughout your home, taking a few simple steps can help control the problem.
Step 1: Find the source
Observe where the ants are gathering and follow their trail if possible. Look for cracks, gaps around pipes, window frames, and other potential entry points.
Identifying the route helps you address the problem instead of repeatedly removing individual ants.
Step 2: Remove food sources
Clean kitchen counters, sweep floors, and vacuum areas where crumbs may accumulate. Pay particular attention to spaces beneath refrigerators, cupboards, and cooking appliances.
Keep sweets, cereals, bread, and other attractive foods in tightly sealed containers. Empty rubbish bins regularly and clean sticky residue from their interiors.
Step 3: Clean ant trails
Wipe the areas where ants travel with ordinary household detergent and water, following the product instructions. This helps remove food residue and the chemical trails that guide other ants.
Avoid mixing cleaning products, especially bleach with ammonia or acidic cleaners.
Step 4: Eliminate unnecessary moisture
Repair dripping taps and leaking pipes. Dry wet countertops, check beneath sinks, and avoid leaving standing water in containers.
Reducing access to water can make your home less attractive to ants.
Step 5: Seal entry points
Use an appropriate sealant to close small cracks around windows, doors, pipes, and skirting boards. Install or repair door sweeps and window screens where necessary.
Preventing ants from entering is often more effective than repeatedly treating the areas where they gather.
Step 6: Use ant bait when necessary
If ants continue to return, a commercially available ant bait designed for the species involved may help control the colony. Follow the label instructions carefully and place the bait where children and pets cannot reach it.
Avoid spraying insecticide directly onto bait unless the product instructions specifically allow it, because sprays can interfere with ants carrying the bait back to the colony.
Step 7: Monitor the situation
Continue checking the affected areas over the following days. Ant activity may not disappear immediately after bait is introduced.
If large numbers of ants keep returning, or you suspect a nest inside a wall or another inaccessible location, consider contacting a qualified pest-control professional.
Are Ants Dangerous to Your Health?
Most ants commonly found inside homes are primarily a nuisance rather than a serious health threat. However, some species can bite or sting, and ants moving between rubbish, drains, and food-preparation surfaces may contaminate exposed food.
Keep food covered, discard food that has been visibly contaminated, and clean affected preparation surfaces thoroughly.
Certain species can also cause structural or electrical problems. For example, carpenter ants may damage damp or decaying wood while nesting. If you notice persistent ant activity alongside damaged timber, investigate the underlying moisture problem and seek professional advice.
