How do you catch shrews in a house?

To catch shrews in a house, set up humane traps baited with food such as peanut butter or insects in areas where you've seen signs of their presence, like droppings or tunnels. Place the traps along walls or in dark corners where shrews are likely to travel. Check the traps regularly to release any captured shrews safely outside, away from your home. Additionally, sealing entry points and removing food sources can help prevent future infestations.
