Squirrels will stop raiding bird feeders if gardeners use a common kitchen spice, according to bird experts. Chilli powder, which squirrels strongly dislike, can be dusted over seed and suet mixes to keep the animals away without affecting birds.
Why chilli powder works
Squirrels are determined animals that can cause significant damage in gardens and can be extremely noisy. They can climb polished steel poles, leap more than eight feet, and their tails give them balance to cross long lengths of thin wire.
The RSPB recommends dusting a small amount of the pungent powder over seed and suet mixes in feeders and on tables. It deters thieving squirrels while not affecting birds' feeding habits.
How to apply the deterrent
Gardeners should ensure seed mixes are thoroughly coated but not hidden in the powder. The recommended method is to put the powder in a bag with the seed mix and shake it up. Other kitchen deterrents include curry powder, Tabasco, Peri-Peri sauce, red pepper, and cayenne pepper.
Experts at bird retailer Duncraft agreed, saying chilli can be a "very useful product when it comes to keeping squirrels away from bird seed". They added, "While birds don't really have a sense of smell or taste, squirrels absolutely do! The taste and smell of chilli can be just as irritating to their noses and taste buds as it is to those of us that don't appreciate hot, peppery foods."
Other uses in the garden
Chilli powder can also protect germinating seeds and plants from pests like slugs and snails. Chilli contains capsaicin, a natural repellent that keeps garden invaders at bay. Simply distribute a small amount over the garden or at the base of the plant you want to protect.
Duncraft noted there are many squirrel-deterring bird foods, such as seeds, suets, and seed additives that contain hot pepper products, usually chilli peppers, powders, flakes, or derivatives. This method is simpler than putting up barriers, as squirrels are nimble and clever animals that usually find a way in anyway.
