Quick verdict
Ten green PP plastic slug stations about 3.9 by 4.4 inches, each a cup sunk into the soil with a pentagonal lid that keeps rain out of the beer and lets slugs and snails crawl in under it, so a bed of hostas or lettuce is ringed with traps that work for a week between refills instead of a night. An open saucer of beer is diluted by the first shower and drunk by the hedgehog; a lidded station is neither. Ten covers a vegetable bed and they rinse and go back for years.
Strengths
- Lid keeps rain out so the bait lasts a week
- Slugs and snails crawl in under the rim and drown
- Ten stations ring a bed or a hosta border
- Reusable PP plastic; rinse and reset
- Takes beer, yeast water or any slug bait
Weaknesses
- Must be sunk with the rim at soil level or slugs walk past
- Emptying is unpleasant; do it before the heat
- Green plastic is hard to find in a dense bed

Beer, But Keep the Rain Out
A saucer of beer catches slugs on the first night and is rainwater by the third. A lidded station keeps working. Mysora’s traps are ten green plastic cups with a five-sided lid that sheds rain and leaves a gap at the rim for slugs and snails to crawl in, sunk round a bed of hostas or salads and refilled once a week.
This review is based on the listing specifications and on how covered beer traps perform against slugs and snails generally. We have not used these traps ourselves and the brand is a generic importer.
Setting Them
Sink each cup beside the plants with the rim exactly at soil level; a rim standing proud is a wall slugs will not climb. Pour in an inch of beer or a yeast and sugar solution and clip the lid on. Set one every three or four feet round the bed, and a couple in the middle of a big hosta planting. Check every few days and refill weekly. Slugs follow the smell, slip under the lid and drown.
The Lid
Rain is what ends an open trap, by diluting the bait and overflowing the cup. The pentagonal lid sheds it and keeps the smell concentrated under cover, so the trap is as good on day six as on day one. It also keeps a thirsty dog and a hedgehog out of the beer.
Bait
The cheapest beer works. So does a teaspoon of dried yeast and a spoonful of sugar in a cup of warm water, which costs nothing. Commercial slug attractants fit too.
Emptying
Lift the cup, tip the catch onto the compost heap or into a hole, rinse and reset. Do it in the cool of the morning. Ten traps is ten minutes.
Where They Fit
Hosta borders, lettuce beds, strawberry rows, dahlia beds in spring, seedling beds. Anywhere the night leaves holes in leaves. They are one part of a slug plan with barriers and evening picking, and the part that works while you sleep.
Who Should Buy It
- Hosta and dahlia growers.
- Vegetable gardeners losing seedlings overnight.
- Anyone who prefers traps to pellets.
Common Owner Complaints
Traps set too high catch nothing. Rim at soil level, always.
Technique Tips
Set the traps a day before planting out, so the local slugs are reduced before the seedlings arrive. Keep the bait an inch deep; a full cup lets a slug climb out.
Alternatives to Consider
Copper tape on pot rims. Iron phosphate pellets, which are pet safe. Nematodes for a season-long reduction in the soil.
Verdict
For slugs round a bed, a lidded beer station catches all week where a saucer catches one night, and ten of these ring a bed for years. Sink them level, refill weekly and empty them in the morning.

Mysora 10-Pack Reusable Slug and Snail Traps with Pentagonal Lid for Beer Bait, Green FAQs
Dig a hole beside the plants, sink the cup so the rim sits level with the soil, pour in an inch of beer or a yeast and sugar solution and fit the lid. Space them every three or four feet around the bed.
Rain dilutes open bait and fills the cup; a lid sheds rain and keeps the smell concentrated so the trap works for days. It also keeps pets and hedgehogs out of the beer.
Cheap beer, or a teaspoon of yeast and a spoon of sugar in warm water, which slugs find just as attractive. Refresh weekly.
They reduce the population around the bed. Combine with a copper tape or a dry mulch barrier and evening hand picking for a bad year.
