As September marks the start of spider mating season, UK households are bracing for an influx of eight-legged visitors. However, a simple and affordable houseplant may offer a natural solution. Online garden centre Primrose has highlighted Lemon Balm, a fragrant herb costing just £2.30, as an effective spider deterrent.
Lemon Balm, known for its citrusy scent, repels spiders and fruit flies without the need for harsh chemicals. Spiders dislike citrus smells, which are overpowering to them but pleasant to humans. To use, take a cutting of lemon balm, steep it in water, and spray the solution in dark areas of your home to clear out hiding spots.
Evie from Primrose explained: 'There’s many old-wives’ tales about how conkers can repel spiders – but many don’t know that a lot of fragrant plants can do just that. Most spider-deterring plants have a strong odour since aromatic plants are generally more effective at repelling insects – but they still smell great in your home too.' She also advised keeping the exterior of your home free of debris, leaves, and wood piles to reduce potential hideouts.
Alongside Lemon Balm, Primrose listed five other houseplants that repel spiders: basil, lavender, mint, rosemary, and eucalyptus. Basil can be used to make a DIY bug-repellent spray, while lavender cuttings can be hung in rooms. Mint leaves can be steeped in water and sprayed on entry points, and rosemary, though faintly scented to humans, emits an intense odour to spiders. Eucalyptus sprigs can be placed around the home or mixed with witch hazel to create a spray.
