Dress like a zebra, wash your feet, keep off the beer: insect experts explain what works and what doesn’t – and why some of us get bitten more than others
It’s a good time to be a mosquito or other blood-sucking insect. In the UK and beyond, they are enjoying the summer heat, and there are lots of humans outdoors, some wearing very little, like an all-you-can-eat walking buffet. Some of the humans are drinking beer, which apparently makes them even more irresistible to mosquitoes. Many of us are warm and sweaty, which is all the better for the blood-suckers seeking us out.
Insect populations are changing because of the warming climate and there are organisations keeping an eye on invasive species, especially mosquitoes, which can be vectors for diseases such as dengue and malaria (globally, more than 600,000 people a year die from malaria). The UK “will have a threat from mosquito-borne diseases as time goes on,” says James Logan, professor of medical entomology at the London School of Hygiene and Tropical Medicine, and CEO of Dot, an “odour intelligence” company. “The biggest threats are arboviruses [viruses transmitted by arthropods, especially insects and ticks], such as dengue. We have mosquitoes throughout [mainland] Europe now that can transmit dengue. We also know that we do get those mosquitoes coming across to the UK, but they don’t seem to be breeding here successfully and surviving over the winter.” But, he warns, with milder winters and warmer summers, it is only a matter of time.
