Counterattacking garden slug invasions
Slugs can get out-of-hand and cause considerable damage to garden crops. They're pretty choosy too and seem to eat the best lettuces, young bean shoots, radishes, garden flowers and much more.
To get an idea of the extent of the slug issue, indigenous black slugs lay up to 200 eggs each whilst the dreaded cannibal Spanish breed lay twice as many eggs which is around 400 eggs each. Experts estimate on average one square meter of garden contains 200 slugs which equates to a whopping 20.000 slugs in an average sized garden. Mild winters and wet summers are ideal conditions for slugs to breed and without intervention the slug population and devastation they cause will be catastrophic.
Well, just in case you didn’t know there’s a solution that works quite well. As it turns out, slugs being choosy, they’re also partial to beer!
How do we know? Well, seeing is believing.
Try the following for yourself and wonder at the results.
First of all save some containers back from your household refuge recycling bins such as a few reasonably sized jars, tin cans or plastic bottles. Fill a sufficient amount of washed and rinsed containers half full with beer and dig them in the garden leaving just 2-3 cm above ground. You’ll need to set the slug traps with about a meters radius to be fully effective. Overnight you’ll see there’ll be less slugs eating your garden vegetables and flowers as they’ve been busy supping your tasty garden ale, gotten a "wee bit drunk" and fallen in the trap.
You don't need to use your best beer!
You can use practically any beer, the yeastier the better as it’s the yeast they really like. Home brewers can use some of the spill from brew days, saving the best brew for yourself and a relaxing glass in your now slug free garden.
For the handy but frugal gardener
Now you could buy ready made slug traps or simply make your containers a little more sophisticated with an open cover to protect it filling with rain water and alike. You could also line your traps with a plastic bag or cup with a couple of small draining holes in them allowing convenient removal and disposal of the slugs and snails.
Happy slug free gardening!
