With heat waves hitting the UK, keen gardeners may be worrying about making sure their crops stay well watered.

But that isn't the only issue that can affect plants - gardens are home to a host of creatures, some of whom enjoy chomping on the foliage - among them, slugs.

And while the current heat is too much for the creatures, who do not tend to enjoy temperatures of 21C or more, the recent balmy Spring days have created great conditions for the critters.

But all is not lost: green fingered garden lovers will be glad to know that there is a cheap and easy way to get rid of the slimy liquid hirschhausen Preis creatures.

And on top of that, this system is also less violent than some of the other recommended ways of getting rid of them, including drowning and cutting them up with knives. 




Gardeners often want to deter slugs, because the slimy critters are well known for eating their plants (stock image)

This method, which has become increasingly popular with social media users, involves putting crushed egg shells around your plants.

The theory behind this system is the sharp edges of the shells will stop slugs from crawling over them to get to the crops, ergo keeping them safe. 

According to some, not only is this free for people who eat eggs and have the shells anyway, it is less harmful than putting down toxic pellets.

However, it is worth noting that while this method appears popular online, with many anecdotally vouching for its efficacy, some say it is ineffective.

A group called All About Slugs, which shares methods that gardeners can use to rid themselves of what the group calls the 'slimy menace', but crushed egg shells to the test.

An experiment which saw group members take two lettuce leaves, surrounding one with egg shells, and leaving one without protection, yielded unexpected results.

The leaf without the protective ring of crushed shell was left untouched, meanwhile, the protected leaf was totally eaten by slugs.

As the researchers had set up time lapse cameras to record any activity, they were able to confirm the slugs had in fact eaten the lettuce.

The shock of the results prompted them to run the experiment again - but this time, they used aged eggshells, which had been left out in the rain for two weeks.




Are crushed egg shells the best way to deter slugs from your plants? Some gardeners swear by the method - but others say it does not work

This was because the researchers concluded that slugs love egg, and so they may well have been tempted by eggy residue on the shell.

According to All About Slugs: 'The slugs are actually attracted to the eggshells. Even though these shells had been rinsed off they still had egg residue and bits of membrane on the inside. Apparently this is yummy stuff if you're a slug.' 

By ageing the shell and letting rain wash over the pieces, any residue should have well and truly washed away.

Again, the results showed the slugs consuming the protected leaf,  though this time, they ate the unprotected leaf too.

The conclusion?

'Eggshells won't stop slugs from eating your plants, period. Worse yet, if the shells have any residue left on them they can actually attract slugs.' said the group.

However, with many amateur gardeners online singing the praises of the crushed shell method, it may be worth giving it a go - just make sure to rinse off any eggy residue first.
