Yeewwwwww----there is nothing more disconcerting than cleaning a beautiful head of Might Joe lettuce and discovering slugs....Slugs, imagine a snail without its shell, are a problem for us this year. These slimy creatures which could star in a B Hollywood horror movie are voracious eaters and leave a trail of slime on the plants as they eat through your garden at night.
They love moist habitat, so if overwatering or rains occur, be prepared to battle the nasty invaders.
There are many home gardeners methods of ridding the garden of slugs. The simplest is to hunt them down and squish them or take a salt shaker to the garden in the night. Shaking salt on them will cause the slug to dry out, but don't over do it since salt is deadly for growing plants.
We also have the drinkers solution to killing plants. Placing a saucer of beer near the infested area will draw the slugs for party time, but when they decide to crawl in for a sip, they will drown in the beer. Be sure the saucer is deep enough that the slimy creature can't crawl out after imbibing. Spreading coffee grounds is a much touted method of killing slugs, however, we have not used them. From research on the Internet it appears that it is more of a wive's tale that coffee grounds actually kill, but may be a deterrent. Most of the information does not give credence to the use of coffee grounds.
My DH mixed up a combination of one part ammonia to nine parts water and sprayed only in the areas where he found slugs in our lettuces. He said the varmints aren't so evident now, but it could be that the areas are drier now.
Do you have any ideas on killing these disgusting creatures? We would all be much obliged to hear your method. Thanks.
