There are many slugs this years due to the mild winter and wet spring. Hated by gardeners, they die horrible deaths. The biological way to get rid of snails fast is the use of nematodes; parasites that enter the slugs through the mouth and arse and kill them from the inside. Chemical ways force all the slug’s fluids to leave the body. Also slugs are cut in half, run over by cars and bicycles, or drowned in beer.
