🐜 PEST SPOTLIGHT #5 – White-footed House Ant (Technomyrmex difficilis)
Think you’ve got Argentine ants? 🤔 It might actually be the White-footed House Ant! These tiny invaders are becoming increasingly common around Canterbury and are often mistaken for other ant species.
🌏 Origin
Native to tropical Asia, White-footed House Ants have spread to several countries, including New Zealand.
📏 Size & Appearance
• Workers are 2.5–3 mm long
• Dark brown to black body 🖤
• Distinctive pale yellow-white feet 🦶
• Form long, busy trails between food sources and their nests
🏡 Where do they nest?
You’ll often find them:
🌿 In gardens and mulch
🌳 Around trees and shrubs
🧱 Inside wall cavities and roof spaces
🏠 Around homes and commercial buildings
🍯 What do they eat?
White-footed House Ants love sugary foods and feed on the honeydew produced by aphids and scale insects. Indoors they’ll happily help themselves to sweet foods left on benches and in pantries.
⚠️ Why are they a problem?
• Invade homes in large numbers
• Contaminate food preparation areas
• Protect aphids and scale insects, increasing plant damage 🌱
• Establish multiple nests around a property, making them difficult to eliminate
💡 Did you know?
Unlike many ant species, White-footed House Ant colonies spread by “budding.” Instead of a queen flying away to start a new colony, queens simply walk with a group of workers to establish a new nest nearby. This allows infestations to spread rapidly across an entire property.
📞 Seeing long trails of tiny ants around your home or business?
Correct identification is the key to successful treatment. Different ant species require different control methods, so a professional inspection can save time and frustration.
