No Bite

The hubby cleared the land of tumbleweeds and we noticed a few strange noises in the house after that. He thinks field mice may have gotten in through the dryer vent. He placed a wire mesh over it and set up a few traps outdoors and in. One lil tiny baby mouse ran out the front door and we caught another mouse in a trap. This trap and a few others have been out over a week and have caught nothing. Do you think it is safe to put put them all away now?
