A FAST food fan has been hailed as a "genius" after revealing how to get rid of insect pests - just by making nifty use of your leftovers.
A crucial ingredient has been shown as the way to fend off any invading fruit flies and gnats after you've tucked into lunch.
And viewers are loving how a woman has shared online, in a video which has gone viral, her method for dispersing invading insects.
She showed the importance of keeping open a small pot of leftover garlic oil or butter, which is often handed over as a free extra when ordering takeway pizza, kebabs or fish and chips.
The sweet scent appears to attract the bugs - yet allows any quick-thinking bystander to trap them in the paste and then amid the lid.

The process was captured in three photos taken over five minutes and shared on Facebook.
The social media video's uploader wrote: "Just a heads up for anyone that are dealing with pesky gnats or fruit flies.
"Open up a cup of garlic butter and they go straight to it. This picture is after about five minutes of opening it.
"It's gross but it's better than having them fly around everywhere."
A whole swarm of bugs can be seen being trapped inside the lid.
One admiring watcher remarked, "Nice! Maybe my fruit flies will go to that", as another dubbed the idea "genius".
The hack was also labelled "Good idea", while another suggested: "I need this for my room!"
The trick was evidently put to the test elsewhere, with a fan stating: "10/10 recommend the garlic butter dig hack for gnats."
She added: "I've tried everything and this has been the most effective."
