Beds and boards
Best slug bait
The best slug bait for a vegetable bed is an iron phosphate product used as the label allows, scattered where Slug and snail (garden) will find it, not piled in a heap a pet can eat. Beer cups catch a few and leave the wet board-and-mulch harborage intact. Metal salt baits that are more toxic to dogs are a different risk. Read the active ingredient. If it is not iron phosphate and the bed is a garden, stop and read harder.

Which one to buy
Labeled product
Iron phosphate slug bait
Best bait — Iron phosphate, Sluggo-style. Scatter. Do not leave a pile. Water only as the label says. Keep the rate. Pets still should not be invited to eat bait, even when the active ingredient is the less dramatic one.
Hardware
Copper slug barrier tape
Best barrier — Copper tape on a clean rim is a physical barrier. It fails when a leaf bridges it or the rim is dirty. It does not treat slugs already inside the bed. Use bait or hand pick for those, and dry the mulch.
Buy less hiding place
Slugs need moisture and cover. Boards, thick mulch against lettuce, and evening irrigation are the habitat. Water in the morning, pull mulch back from stems, and turn boards you do not need. Bait on a permanently wet, shaded mat is a refill subscription. UC IPM’s slug note is the reference if you want the non-product steps in one place.
Common questions
What is the safest slug bait around pets and vegetables?
Iron phosphate products are the usual extension recommendation, and only as that label allows in a food garden. “Safer” is not “leave a pile where a dog eats it.” Read the pet warning anyway.
Do beer traps work?
They catch some slugs that fall in. They do not beat a wet harborage. Use them as a hobby beside bait and drier cover, not as the program.
Will copper tape replace bait?
On a raised bed with a clean rim, it keeps some slugs out. Slugs already in the soil still need picking or a labeled bait. Leaves that touch the rim are a bridge.
