The mix is then enhanced, by the inclusion of fast and slow releasing energy sources and assorted naturally sourced vitamins and mineral. All this combines to create a superb all season food bait that has a subtle complex smell and a rich red colour. As with all Sticky Baits shelf life baits, this is as close to their freezer bait as possible. Anyone already using Bloodworm Freezer Bait knows it's worth keeping a kilo or two of shelf life in the car. Available in 12mm, 16mm and 20mm in 1kg bags or 5kg bags. (Image may differ on size, see below for correct size.) Flavour Bloodworm. Size 12mm. Bottom bait. Bag size 1kg.
