How to keep bait fresh and alive
Store worms, maggots, casters and live bait so they're still lively at the end of the session, not the start.

What this skill is for
Bait that has gone soft, sour or dead in the box is nearly invisible to a fish that has options. Most bait is a living thing, and it needs the same three things you do: a stable temperature, air, and cleanliness.
What you need
- Breathable bait boxes
- Dry peat or coir for worms
- A cool bag or shaded storage
- Clean water and an aerator for live bait
Step by step
- 01
Keep worms cool, dry and breathable
Store them in dry peat or coconut fibre in a box with ventilation, out of the sun. Pick out dead and swollen ones daily — one rotting worm spoils a whole box.
- 02
Control maggots with temperature
Cool slows them down and keeps them firm; warmth speeds them up and turns them into casters. A fridge door or a shaded cooler is the difference between a box of lively bait and a box of liquid.
- 03
Keep casters damp and cool
Casters don't need feeding and don't like heat or airtight boxes. Rinse them occasionally, keep them cool and use them within a few days.
- 04
Keep live bait oxygenated and shaded
A bucket in the shade with an aerator, clean water from the water you're fishing where possible, and no direct sun. Change the water if it goes cloudy, and never put warm hands in it.
- 05
Keep your hands neutral
Suncream, insect repellent, petrol and soap all transfer to bait and fish can taste them. Rinse and dry your hands before handling bait.
- 06
Transport in the cool, not the boot
A car boot in the sun cooks bait in half an hour. A cool bag in the footwell, or the passenger footwell with a damp cloth over the box, keeps everything alive.
Where it goes wrong
- Sealing worms in an airtight, wet box.
- Leaving bait in the car while you set up.
- Storing bait next to groundbait, tackle with fish oil on it, or a fuel can.
- Handling bait with hands that smell of suncream.
