Gardeners are being encouraged to reach for a simple kitchen staple costing as little as £1.10 to tackle common garden pests without resorting to harsh chemicals. Experts say a widely available household spice can act as an effective natural deterrent against unwanted visitors such as ants, aphids and other insects that can quickly damage plants.
The method is not only budget-friendly but also safer for pets, wildlife and the wider environment compared to traditional pesticides. The trick involves sprinkling the spice directly onto affected areas of the garden, including around plant bases, along pathways and near entry points where pests are most active. Gardening expert Martha Stewart wrote on her website: “A little bit of heat from cayenne pepper goes a long way in the kitchen—and the same goes for your garden.

“Sprinkling cayenne pepper near the base of plants can discourage some common garden pests that dislike the overwhelming pungency of this pantry staple.
“Like humans, some pests experience a strong, unpleasant, burning sensation when they come in contact with cayenne pepper, which may send them looking for another meal somewhere else—far away from your vulnerable garden plants.”
As well as being cheap and easy to use, the solution is appealing for those looking to adopt more eco-friendly gardening practices.
Chemical pesticides can harm beneficial insects like bees and ladybirds, whereas natural alternatives allow gardeners to protect plants without damaging the broader ecosystem.
While the method may need to be reapplied after rain or watering, many gardeners report seeing noticeable reductions in pest activity after consistent use.

Despite its effectiveness with pests, Stewart warns that there are downsides to the technique that home owners need to be aware of.
She added: “There are some downsides to using cayenne pepper in the garden. Even though it won’t permanently affect animals, it’s not pleasant for them if they sniff or lick the pepper, or somehow get it near their eyes.
“While cayenne pepper may be effective in keeping pests away from your plants, you may not want to risk causing them discomfort. In the same vein, you will need to keep your pets away from cayenne pepper you sprinkled or sprayed around your garden.
“What’s more, while cayenne pepper can be effective at deterring harmful pests from bothering your plants, it can negatively affect good bugs.
With spring approaching and pests becoming more active, experts say now is the ideal time to try simple, low-cost solutions.
