Asian Tiger Mosquito

Fascinating facts about the Asian Tiger Mosquito

• A mosquito the size of a sesame seed has invaded 6 continents in 40 years, hitching rides in used tyres and potted plants. The Asian tiger mosquito wasn't found outside tropical Asia before 1979; today it breeds in 80+ countries, from California to southern Europe. It carries dengue, Zika, and chikungunya viruses that infect 400 million people yearly—making a striped insect barely visible to the naked eye one of the deadliest disease vectors on Earth.
• Female Asian tiger mosquitoes are the only bloodsuckers in the pair, and they hunt in daylight when most people forget repellent. Males sip nectar and never bite—their mouthparts are shaped for flowers, not skin. A female can smell human breath from 50 metres away and will follow a person indoors through open doors, making this species far more dangerous than night-biting mosquitoes because we're awake and unprepared when they strike.
• A single female can lay 100 eggs every 3 days without ever visiting a large body of water. Unlike most mosquitoes that need swamps or ponds, tiger mosquitoes breed in bottle caps, birdbaths, gutters, and leaf axils—any pooled water the size of a teaspoon. One small puddle in your garden can produce hundreds of biting females, which is why controlling them means emptying every container around your home, not spraying swamps.
• The tiger mosquito's black-and-white striped legs and body are not camouflage—they're a warning. Predators learn to avoid them because tiger mosquitoes are toxic, containing alkaloids that poison dragonflies and spiders. By advertising their danger with stripes, they waste fewer energy fleeing; predators leave them alone and hunt safer prey instead.
• Within 48 hours of a blood meal, a female tiger mosquito's ovaries swell to 40% of her body weight—a burden equivalent to a 70-kilogram human carrying 28 kilograms of eggs. She then searches frantically for the tiniest water source to deposit them before she starves. This extreme reproductive drive, combined with her ability to breed in household containers and bite during the day, explains why this species has conquered the world faster than any other mosquito in history.
