Adding a small amount of chilli powder to bird feed can deter rats and squirrels while keeping birds safe, according to gardening expert Dave, known online as Dave the Plantman. In November, rats actively seek warm shelter as outdoor temperatures drop and natural food sources diminish, driving them toward human habitations and waste.
A Simple Kitchen Spice Solution
Dave shared the tip in a video on Instagram, where he spoke with Bob, a supplier of chilli powder. Bob suggested mixing chilli powder with bird feed as a way to attract birds while putting off rats, mice and squirrels, as they find the smell off-putting.
Bob explained: "Something like that, we'd put a level teaspoon in, and it will deter rats, mice, squirrels. I've even got a customer in Cumbria who puts it on her roses to keep the deer off." He added: "I've also been told by other customers if you put it around your bulbs when you're planting them, it will deter them from digging them up."
Safe for Birds When Used Sparingly
When used in small quantities, chilli poses no danger to birds. Adding a tiny amount of chilli powder to bird feed is a tried-and-tested technique for putting off squirrels and rats, as they are particularly sensitive to the spice and will steer clear of the food entirely. The trick is to use it sparingly to prevent potential irritation and to make sure the powder does not get into the birds' eyes.
To apply, simply sprinkle a small amount of chilli powder lightly into the seed mix or suet before topping up the feeder, ensuring the food is evenly coated to prevent clumping.
Keeping Rodents Out of the Garden
To stop rats or mice from coming near a property, sprinkle chilli powder or chilli flakes around entry points and possible nesting spots. As capsaicin irritates their sense of smell, they are unlikely to linger where it has been used. Alternatively, mix chilli oil or powder with water to create a solution and apply it around the area, topping it up again after rainfall. During winter, when wet weather is regular, reapplication may be needed more frequently.
While chilli is harmless to birds, it can cause irritation to household pets such as cats and dogs, so care is advised when applying it to prevent direct contact or ingestion. The method is considered humane, causing rats no physical harm, but rain can wash away the powder or spray, requiring regular reapplication. For a full-scale infestation, seeking professional advice is recommended.
