Penny trick to deter wasps from your BBQ

'There's nothing worse than when you're having a nice BBQ party with friends and family and there are bugs flying about,' says Chris Bonnett, founder of Gardening Express.

'They can be a real pain but there are a few inexpensive ways to keep them away. One popular and cost-effective way of keeping bugs at bay is to use glasses of water with pennies in – this confuses the insects by using light reflection.

'All you need to do is fill up a few glasses of water and drop three pennies into each one. Place near your barbecue, and the flies should steer clear of you and your food.'

The fans of cleaning whizz Mrs Hinch are all over this penny trick as a method for deterring wasps and other insects, and many claim it works too. Her social media is a-buzz with fans sharing their own take on the trend.

One woman recommends using a sandwich bag instead, half-filling it with water and dropping a few coins inside. She said: 'A clear plastic bag half filled with water with a few coins in it. Hang on windows/doors and you won’t see a fly in your house. They think it’s a hive and won’t go near it.'

Wasp psychology 

Gardening guru David Domoney has also been sharing his own tips to get rid of garden pests and when it comes to wasps, he agrees that the most important thing is to understand their motivations and act accordingly. 

'Their lifecycle determines the type of behaviour they exhibit at different times of the year. At the beginning of summer, wasps are busy collecting materials to build their nests and this makes them hungry for protein.

'If you have a BBQ, a picnic or an alfresco sandwich, quickly clear away anything with meat on it, such as a used grill or leftover food. Towards the end of summer, wasps tend to switch their attention to anything sweet. Worker wasps binge on sweet food before they die.'

We're off to collect our loose change and try this wasp prevention trick in our BBQ area immediately.
