As temperatures rise across the UK, rats and mice become more active, with summer marking their peak breeding season. Rodent numbers soar between March and October, increasing the risk of these pests entering homes and gardens.
For those seeking a humane yet effective solution, a simple homemade spray using common kitchen ingredients can deter rodents. Garlic, white vinegar, and cayenne pepper or chilli flakes are all known to repel rats and mice due to their strong scents and irritant properties.
To make the spray, combine one tablespoon of cayenne pepper or chilli flakes, one cup of white vinegar, three to four crushed garlic cloves, and one quart of water. Mix and pour into a spray bottle, then apply to areas where rats are likely to appear. For a stronger formula, use two cups of vinegar.
Alternatively, boil the cayenne and garlic in water, cool, then stir in vinegar. Strain if desired before spraying. Exercise caution with chilli and keep children and pets away from treated areas. Note that vinegar may damage certain surfaces.
Pest control experts confirm the effectiveness of these ingredients. Native Pest Management states that cayenne pepper irritates rats' sensitive noses, while vinegar's acidic aroma deters them. Pest Pointers explains that garlic's allicin compound acts as a natural defence mechanism against animals.
