Had this issue before, no matter what i put on the trap the mouse wouldn’t take it, this went on for months, so i then tried poison but again with no luck, even humane traps didn’t work
In the end i had no option but to use a glue trap, horrible things, very inhumane but id had enough, as soon as i heard the mouse had been caught it was quickly dispatched with
Id only recommend it as a last resort and do it when your other half and kids are away
Any future mice will be given the chance to be caught in a humane trap before having the option to die via trap or poison, glue traps are truly the last option
