Answer: It sounds like you have heard of all the remedies there is for slugs. All the home remedies will work for a time, but need to be reapplied periodically. The copper strips around the bed are the best control I know of, as long as you remove all the slugs inside the bed first! There are a number of chemical controls such as the ones you've mentioned, but you need to be careful about kids and pets being around the area where you spread the slug bait. Generally, remove mulch and and objects slugs can hide under, cultivate the soil frequently and use raised beds to dry it out and weed regularly. Stick with it and your sunflowers will survive.
