Each year at this time they start looking for a good secure place to nest and raise their young. I took this one down the road and turned it loose as I don't like to kill them regardless of how destructive they are. Some people I know catch them and turn them loose at other peoples houses. That is probably the lowest form of human I know. One year we were recipients of 19 of them. I take them where they can live away from homes. We keep our hoods up on our vehicles since they seem to prefer closed spaces. Let one get at your wiring harness and they can cause thousands of dollars damage.
So Mrs. pack rat has new digs and hopefully we won't see her again. As she was scampering off I did think I heard her yell back "I'll race you home", in which case I'll have to set snap traps. These rodents have also been known to chew the insulation off your electrical wiring and cause house fires. We have chicken wire sealing off our wiring so first they will have to chew through that which I suspect they would do if they wanted to. Like I mentioned, they are also smart little buggers.
