Garden pest

Slugs & snails

Night feeders that rasp holes in seedlings and leave slime trails.

Crops often hit: Lettuce, Hostas (nearby), Seedlings, Strawberry

How to identify

  • Irregular holes with smooth edges
  • Shiny slime trails on soil or leaves
  • Active on damp nights and cloudy days

Damage: Destroyed seedlings; chewed greens and ripe strawberries.

Control methods

  1. Hand-pick at night with a flashlight.
  2. Beer traps or board traps — empty daily.
  3. Reduce daytime hiding spots (boards, dense weeds) near beds.
  4. Water in the morning so surfaces dry by night.

What products to use

We list product types and what to check on the label — not brand rankings, prices, or “we tested” claims. Always follow the label for your crop, and prefer the least disruptive option that works.

  • Iron phosphate slug bait

    When: Persistent damage after hand-picking

    Look for: Iron phosphate (not metaldehyde near pets/wildlife if you can avoid it); scatter thinly per label
