7 Diseases You Can Get from Common Household Pests

Southern Africa is home to several common ant species that regularly invade homes, gardens, and workplaces. While they’re not typically dangerous to humans, they can quickly become a frustrating household problem once they settle in.

Here are the most common types you’re likely to encounter.

Black Garden Ants

These are the everyday ants most people recognise. They’re usually seen forming long trails in kitchens or along walls, especially where food is present. They’re highly attracted to sugar and crumbs, which makes homes an easy target. Although they seem harmless, they multiply quickly and will keep returning if food sources aren’t properly removed.

 
Pharaoh Ants

Pharaoh ants are very small, pale-yellow ants that often hide inside homes. They tend to nest in wall cavities, cupboards, and even electrical appliances, which makes them difficult to detect early. The biggest issue with Pharaoh ants is that disturbing them can cause the colony to split and spread, making infestations worse instead of better.

Carpenter Ants

Carpenter ants are larger and more destructive than most other species. They don’t eat wood, but they tunnel through it to build their nests, which can weaken structures over time. You may notice them around wooden frames, roofs, or furniture, especially if there’s moisture damage present.

 Fire Ants

 Fire ants are aggressive outdoor ants known for their painful stings. They usually build nests in soil and become defensive when disturbed, making them a risk for children and pets playing outside. They are most commonly found in gardens, lawns, and along pathways.

Argentine Ants

Argentine ants are invasive and extremely persistent. They form large colonies and are quick to invade homes in search of food and water, especially during dry or cold periods. Once they establish themselves, they can be very difficult to eliminate because multiple colonies often work together and spread rapidly.

Ants may seem small and harmless, but different species behave very differently, and some can become serious household pests if left unchecked. Identifying the type of ant is the first step in controlling the problem effectively before it spreads further into your home.
