My homemade slug traps

Here's how I make my slug traps.Get a 1 lb. butter tub and put 4- 1/2 holes close to the top,I used the yellow painted part as a guide.

 Slugs  will go for almost anything,soda,beer,sugar water,I was told by a twitter friend that soapy water works too so I'm going to that give a try later on .

 Here's a slug trap placed in my pumpkin patch.Keep the holes above the soil and place some weight on the cover because we don't any drunken squirrels on the rampage ha ha.
