I love to garden but I hate slugs. Spiders and snakes: no problem. Moles and gophers: my cat, Pomeranian, or husband will dispatch those. Slugs are more prolific and tougher to get rid of.
After trying for over a decade, I won the battle of the slugs using three methods. The first method was an accident, sort of. I knew that slugs would die if you salted them. I wasn’t going to salt my lawn or flowers. However, in a fit of rage, I grabbed a spray bottle of cheap (Dollar Tree) orange cleaner with oxy-bleach. Guess what? The slugs practically melt before your eyes after spritzing it a half dozen times. I was positively giddy killing those slimy leafeaters! However, with hundreds of the vile critters, (over a dozen per two square feet), it would have taken forever to hunt them down. Besides, my trigger finger went numb after the first twenty minutes.
To the rescue: my husband. He said he remembered something about sisal rope deterring slugs. He stapled half-inch rope on top of the wooden edging around the beds, making sure there weren’t any open spots. Voila! We watched as slugs climbed up the sides of the boards and turned around and went away. Of course, by now we had two spray bottles. They could slither away but were soon dark spots on the grass, waiting for natural decomposition.
While these two eradication programs were going on, we had a benevolent act of nature occur. The wild turkeys that come by twice a day to feed on spilled birdfeed (I think the blue jay does it on purpose) decided to fly over my deer-proof fence. The ten or so turkeys wiped out the rest of the slugs. After two weeks, I found one slug. He was trapped within the borders of the raised bed, unable to get out over the rope. I tossed him into the grass. Maybe a turkey will come by for a snack.
