Vegan housemate prevents us from stopping mouse infestation

so my uni house has got a mouse infestation but we live with a raging militant vegan who won’t let us do anything about it. We’ve tried all sorts like humane traps and blocking up holes and everything imaginable but the vegan housemate purposely disarms the traps and everything else he can do to sabotage us! We support their lifestyle choice but we’re at the end of our patience with it! we don’t want to live with mice anymore!
