Slugs and snails can cause a lot of damage in the garden. You put a lot of work into growing and caring for vegetable and fruit plants and in one night everything is eaten away. However, not every slug is a plant pest. Some species are even beneficial insects and help you in the garden. In this article, you can find out what types of snails there are and how you can control and repel harmful snails.
As a long-time gardener and elderberry shrub enthusiast, I’ve dealt with my fair share of pesky snail infestations over the years. These slimy, slow-moving mollusks can quickly devastate the beautiful foliage and fruit production of American elderberry shrubs when left uncontrolled. If you’re struggling to manage snails on your elderberries, you’ve come to the right place. In this comprehensive guide, we’ll cover everything you need to know to get rid of snails on American elderberry shrubs for good.
Understanding Snail Behavior and Damage
Before we dive into control methods, it’s helpful to understand precisely why snails are so problematic for elderberry shrubs. Snails are nocturnal creatures that thrive in cool, damp environments. During the day they hide out in moist soil leaf litter, and other sheltered spots. At night, they emerge to feast upon tender plant tissue, flowers, and fruit.
Snails use their sandpaper-like tongues to rasp away at the leaves and bark of elderberry shrubs, leaving behind telltale ragged holes and trails of slime. This damage is not only unsightly but can stunt the plant’s growth reduce its productivity and invite infections. A serious snail infestation can quickly defoliate an entire elderberry shrub.
Controlling snails requires an integrated pest management approach Let’s take a look at some of the most effective solutions
Handpicking for Small Infestations
For minor snail problems, handpicking is my go-to method. It’s cheap, non-toxic, and highly targeted. I recommend checking plants thoroughly first thing in the morning when snails are most active. Wearing gloves, pluck any snails you find off the plants and drop them into a bucket of soapy water to dispatch them.
Be sure to scout the surrounding soil, mulch, and any protected nooks and crannies where snails like to hide. Repeat daily until you’ve effectively controlled the population. It’s tedious work but well worth it to protect your elderberries.
Traps Using Beer or Yeast
For larger snail infestations, traps are an efficient way to capture and drown the pests. Sink shallow containers like yogurt cups into the soil around your elderberries. Fill the containers with cheap beer, which snails find irresistible. The intoxicated mollusks will crawl in and perish.
Alternatively, you can add active dry yeast and sugar to water to create a lethal carbon dioxide trap. The bait will lure snails in while the resulting fermentation causes them to asphyxiate. Check and empty traps frequently. Combine trapping with handpicking for the best results.
Copper Barrier Tape
One of my favorite snail deterrents is applying copper tape around the bases of elderberry shrubs. The copper reacts with the snail’s slime to deliver a mild electrical shock. This shock won’t kill them but does effectively repel snails before they can access your plants.
For best results, wrap the tape continuously around stems, leaving no gaps for snails to slip through. Upgrade to copper mesh fencing or flashing to encircle entire shrubs and flower beds. Maintain the barriers by polishing tarnished areas as needed.
Diatomaceous Earth
This powdery chalk-like substance made from fossilized algae is a mechanical pest killer. The tiny sharp edges abrade the soft bodies of snails. When applied as a barrier around elderberries, it deters snails from crossing and can cause dehydration.
Sprinkle diatomaceous earth around the base of plants, along garden edges, and around potential snail hiding spots. Reapply after rain or irrigation. Wear a mask while handling to avoid inhaling the dust. Though non-toxic, diatomaceous earth can irritate lungs if inhaled.
Iron Phosphate Baits
When natural remedies fail to eliminate a severe snail infestation, iron phosphate baits are the safest chemical control option. Unlike products containing the deadly metaldehyde, iron phosphate baits won’t harm pets, children, or wildlife when applied correctly. The snails are attracted to and consume the pellets, resulting in fatal digestive issues.
Scatter bait near affected plants according to package directions. Reapply as the bait depletes. Collect and dispose of any dead snails to prevent predators from ingesting the poison. Always exercise caution when utilizing chemical pesticides in your garden.
Prevention Is Key
While control methods can help eliminate existing snail infestations, prevention is critical to avoid reoccurring destruction. Here are some tips to make your garden less hospitable to snails:
-
Remove leaf litter, boards, and other potential snail shelters around your elderberry shrubs.
-
Avoid overwatering and improve drainage in snail hot spots.
-
Clean up any snails found on new plants before bringing them home from the nursery.
-
Spread abrasive materials like crushed eggshells or diatomaceous earth around vulnerable plantings.
-
Check for and address environmental factors attracting high snail populations, like excessive shade or soil compaction.

Catching snails with a beer trap
To do this, fill a preserving jar about halfway with beer and bury it in the bottom. The rim should protrude a little, as this will prevent leaf beetles from falling into the jar and drowning. However, we do not recommend the beer trap , as slugs can still detect the smell of beer up to 100 m away. You may therefore attract more slugs than you actually have in your garden. There is also a risk that beneficial insects such as bees and bumblebees will be poisoned by the beer.
Copper tape against snails
Copper is a heavy metal and can accumulate in the soil over time, causing environmental pollution and potentially harming soil life. Some snail species are also said to cross the belt despite the unpleasant sensation of contact with copper. In our opinion, there are certainly better methods to combat slugs and snails, which are also more environmentally friendly as they do not put additional strain on the soil and its living creatures.
