I used to save and store all manner of baits trusting they would remain effective.Not knowing for sure whether they were deterioating or not and often cursing the lack of interest from fish.
Having just started to make my own baits with recognised ingredients from a respected supplier,I can tell you my confidence levels have shot up.
Being able to use hookbait made earlier that day gives me the best possible chance if fish are present or can be drawn in.
At worst, if I blank I can be pretty sure that it was not due to dodgy well used,tired bait.I would assume that fish were simply not present .Okay there are other factors that come into it,but if you can all but eliminate the hookbait issue that got to be a step in the right direction.
Bait sizes and shapes can be altered to offer a slightly different presentation. if you make your own bait.
I am sure there will be some that will have caught a fish on a boilie that has been rolling about under the car seat for a few years but sometimes barbel will eat almost anything when really up for it.
Before I get shot at for suggesting something exotic or expensive,,,
I reckon you can easily get a seasons worth of bait ingredients for under £100
that two anglers could share if you not fishing at every single oppotunity.
Next time should anyone use a mouldy old pre war, rock hard,boilie and you dont have any joy bet you might give fresher bait a passing thought,
