Slugs seem to be a problem is most gardens, and sometimes you won't even know they are there until there is quite a bit of damage, as these pesky critters work fast, decimating both berry crops and vegetables. They are not that easy to find, either, until you know what you are looking for, including chewed up leaves and their slimy trailings left on your precious plants, and little white eggs on the ground.
Fortunately, there are several ways to combat these slimy little garden demons. And one of them is found right in your kitchen - salt. Just mix up a strong salt solution, put it in your spray bottle, and go into your garden at nightfall, when they come out to feed and spray them. You don't need precise measurements for the salt solution, but make sure it is strong enough - think of salting your pasta water and you should be good. This will kill the slugs in a matter of hours. The next day it is a good idea to give your plants a good watering to remove the salt so it doesn't damage your plants.
This is another great, inexpensive tool that has so many uses in your garden. Diatomaceous Earth (DE) is the fossilized remains of diatoms or algae. While it may look like a fine powder to us, it has lots of sharp edges that will but up soft-bodied insects, such as slugs. Pick a dry day, with no rain in the next day or so, and sprinkle the DE in several spots around your plants, being careful not to sprinkle it on the leaves. You may need to repeat in several days if the problem persists.
Slugs LOVE the smell of beer. There are several ways to build slug traps using beer, but the easiest way is to drink most of a bottle of beer (or pour it down the sink, but I am confident you can find someone to help you in this task) and lay the bottle on its side carefully in the garden with the bottle opening flush with the ground. The slugs will be attracted to the beer, crawl in and drown. Check the bottle in a couple of days and when full discard the contents and recycle the bottle.
As a last resort, you can apply slug bait. Luckily there are some organic options out there but be sure you are using an organic product like Sluggo. Most of these products using Iron Phosphate which is lethal to slug and will not harm your garden.
