Does aluminum foil repell snails

Answer 1

Most people recommend using copper foil as a repellent for slugs and snails. Conventional wisdom suggests that the slugs & snails receive an unpleasant electrical sensation and are deterred from crossing the copper.

I have had reasonably good success using aluminum foil to repel slugs. When we used to feed our dogs in an enamel pan, slugs would constantly invade and eat the dog food. After switching to an aluminum pan, slugs were no longer a problem. Placing aluminum foil around our broccoli plants helped to deter the slugs as well.

Aluminum is a lot cheaper than copper. For planters and raised beds, you can get a roll of self-adhesive aluminum tape at hardware stores (look in the heating/venting aisle); 2 inches wide and 150 feet long for $10-15 US. Copper foil tape is considerably more expensive, and can be found in the garden department.

Note that the aluminum or copper must be uncoated. The coating will prevent the electrical reaction that repels slugs and snails.

=================

I have found aluminium to be useless against snails.

However, copper appears to work.

I have 10 pots in my front garden. I put copper strips on the lips of 3 of them and aluminium strips on the other 7.

I took a photo in my garden last night which shows a snail happily sliding along on the aluminium strips I had carefully stuck on the edge of one of my pots.

There were many others on the other aluminium edged pots (I killed 11 all up from the aluminium edged pots).

However, the 3 pots edged with copper had no snails in them.
