Looks kinda cute huh? These buggers can ravage a garden in one night!
I have tried everything to get rid of them. All of the ideas below. I try to be as organic as I can, but this is one area where I use a product named Sluggo. It has an organic option, that of course is more money. If you really don't want to use Sluggo, here are the suggested ways to deter slugs.
1. Slugs avoid crawling over anything dry, dusty or scratchy, such as lime, diatomaceous earth, cinders, coarse sawdust, gravel or sand. These make great barriers to keep out slugs.
2. Epson Salts sprinkled on the soil will help deter slugs and also help prevent Magnesium deficiency in your plants.
3. Vinegar, a good ingredient for slug sprays and removing slug slime.
4. Spread salt around your plants. Salt dries them out so they won’t go near it.
5. Collect human, dog, or cat hair and put around your plants, not only will the slugs not go on it, but it will also keep a lot of the little critters away also.
6. When you find a slime trail, destroy the track so other slugs do not follow. They will follow each others trail. There are certain plants that slugs hate like the strong smell of mint, chives, garlic, geraniums, foxgloves and fennel. Plant them around the edge of your garden to keep them out. These plants also discourage Japanese beetles.
7. Put stone paths along your flower beds.
8. Put Copper of foil barriers around plants that the slugs are eating. When the slugs cross them they are given a small shock. This also works for snails.
9. If you are find slugs in your potted plants, put petroleum jelly around the base and tops of your plant containers and watch them slip and slide.
10. Fill a shallow bowl with beer and wait overnight. The slugs love it. Dispose of the slugged brew by adding it to your comport.
11. Another slug formula: 1 part ammonia to 3 parts of water. One squirt on the slugs is all you need.
12. After eating your 1/2 grapefruit for breakfast, put it into your garden to make slug trap. Turn upside down after putting a small hole or two on the side for slugs to enter. They adore grapefruit and the slugs will gather there to eat the grapefruit and leave your plants alone. Collect the grapefruit and put into the compost bin.
