Gardeners have been warned to watch out for the box tree moth caterpillar.
The caterpillars, which are the larvae of the box tree moth, eat the leaves and bark of box trees.
In only a few days, they may turn once-beautiful bushes dark, barren, and beyond rescuing.
Ecology specialists at Arbtech have alerted gardeners that the number of caterpillars peak in July and August.
40p solution
But a 40p hack can help keep the pests away from your garden.
A simple bar of soap from Sainsbury’s can prevent caterpillars from ruining your plants.
An unscented bar acts as a repellent as many insects dislike the scent and residue that soap leaves behind.
Simply leave a bar of soap near your plants or rub residue on leaves to keep insects at bay.
Soapy water also works wonders as it dries out caterpillars’ outer layer, leading them to die from dehydration.
For households with children or pets, soap is a low-risk alternative to chemical pesticides, and when used properly, it is less likely to damage pollinators.

Infestations can be disastrous if left untreated with severely affected plants having to be uprooted and replaced completely.
An ecologist from Arbtech told Tivy Side: “Box tree moth caterpillars might look harmless, but they’re an invasive species that can strip a healthy plant in no time – and because they often feed from the inside out, many people don’t realise there’s a problem until it’s too late.
“Box hedging is hugely popular in British gardens, so this species is having a serious impact not just aesthetically, but financially too.
“We’re urging homeowners to check their plants regularly over the summer months.
“Look for tell-tale signs like webbing, leaf loss, or green-and-black striped caterpillars.”
Keep pests out all summer
IF you want to ensure that your home is pest free this summer, here’s what you need to know.
Hornets and wasps – hate the smell of peppermint oil so spraying this liberally around your patio or balcony can help to keep them at bay.
Moths – acidic household white vinegar is effective for deterring moths. Soak some kitchen roll in vinegar and leave it in your wardrobe as a deterrent.
Flying ants – herbs and spices, such as cinnamon, mint, chilli pepper, black pepper, cayenne pepper, cloves, or garlic act as deterrents.
Mosquitoes – plants, herbs and essential oil fragrances can help deter mozzies inside and out. Try eucalyptus, lavender and lemongrass.
