This is an expensive but likely very useful rat trap. The trap is around $200 and you need a $100 to $120 vacuum.
Would the rodents figure it out like they do most traps? Maybe.... only way to find out is to invest $300 plus.
Of course for that price you could buy three treadle feeders and the rodents would leave and not be there to trap.
Where it might come in handy is in flocks where a treadle feeder isn't advisable due to tiny hens. One would have to keep the chicks away from it obviously.
