Gardeners are being encouraged to sprinkle chilli powder in their gardens this June to protect bird food from squirrels and other animals. The technique allows birds to feed without competition, as they are unaffected by the spice while mammals find it unpleasant.
Bird populations have declined significantly due to habitat loss and a shortage of food sources. The RSPB's Big Garden Birdwatch has recorded a steady drop in birds visiting gardens over recent decades. Insect numbers have fallen by up to 80 per cent in the last 20 years, impacting the food chain and putting birds at risk of starvation.
To help, gardeners can leave out mealworms, suet, fat balls, and fruit like apples. The RSPB advises coating these with strong chilli powder or pepper sauce, noting: 'Birds aren't bothered by the chilli, but most squirrels can't put up with the burning sensation and will leave the food alone.'
However, the RSPB warns against using flat bird tables, which were withdrawn from sale in 2024 due to disease concerns. Additionally, seeds and peanuts should not be left out between May 1 and October 31, as they may spread a disease affecting birds.
