Slug

Here is a picture of a slug. I'm not sure what kind this is but they're abundant this time of the year and can be found in cool, damp places. This particular dude was found under the piece of tin Emilie and I flip when looking for snakes at grampy's house. I remember as a kid putting salt, regular table salt, on these critters are they attempted to cross the driveway - they didn't like that too much.

Slugs are best described as snails without shells. They are a type of mollusk, related to clams and oysters. Slugs are soft bodied, generally brownish or grayish, with eye stalks. They vary in size from 1/4 inch to two inches or longer. Slugs leave a silvery slime trail that they secrete as they move. This slim is also very difficult to get off your fingers and hands, if for some reason you chose to pick one up.

Slugs use file-like mouthparts to rasp and chew plant tissue. Because of their mouthparts, they create irregularly shaped holes. Feeding damage can be cosmetic; however extensive feeding can result in plant stress or even death

Trapping and handpicking helps lower slug numbers. To be effective, traps must be checked and cleaned out several times a week (more when slugs are abundant). Be sure to put out enough traps to adequately protect the entire garden.

You can trap slugs by setting out several flat boards, shingles or damp newspapers. Check under these traps the next morning and kill any slugs that are hiding. You can drown slugs in soapy water, crush them, or spray them with household ammonia diluted to a 5 percent or 10 percent solution. Traps containing beer or other fermenting food are popular. Sink jars, cans, pans or similar containers into the ground so the top is level with the ground. Pour beer or a water and yeast mixture (one teaspoon of yeast to three ounces of water) or similar fermenting liquid into the container. Slugs are attracted to the odors, fall in and drown.
