Is this stuff good for colouring maggots?
As they state for hook baits only, I would imagine that there's something in it which is now on the prohibited list for its effect on the environment.
I've never heard of anyone trying it; which would suggest no. It would be an expensive way of doing it even if it did work. Part of the problem is getting powder to stick to the maggots for the colour to take, if wet the maggots can end up escaping.
If you are asking about the new improved (environmentally friendly) version, then I think that it was the colouring which meant that it had to be re-formulated; that would also suggest a no.
Maggots are difficult to dye without them eating the colour in their food, although chrysodine did a reasonable job, it also found itself on the naughty list.
I've always sprinkled maggots with something in the hope that it enhances the bait, I have no evidence to support it, but I have confidence in doing it: tumeric, 5 spice, chilli powder, fennel, star anise, clove etc.. IMO the powders do make the texture of the maggots better and clean them in the process, maize flour seems to soften them. Freezing them I believe draws something into the maggots from the spices (no evidence), but can make them claggy when they thaw out, I prefer liquid for freezing, I cool them down before covering in liquids and then freeze - as stated above, they can crawl up anything!
I don't think that anything has been found as effective as feed dying them. There used to be a liquid available for red maggots, but the results weren't very good, and they need to have a good eye kept on them.
