In Astoria, a lizard frequently finds its way into our ground-level apartment, coming in through the adjacent garage. It's been relocated to various places several yards away, and within a week or so, it's back. We're here twice a year for a total of about four to five months each year, and at least twice have found skin it has shed. Do you have any idea what it is and what it is looking for inside the house?
That is a Northern alligator lizard (Elagaria coerulea) It prefers the edges of meadows in conifer forests, and is also found in riparian zones. This is the only lizard found in the cool coastal forests of northern Oregon. Northern alligator lizards eat small terrestrial invertebrates (termites, beetles, ticks, spiders, millipedes, and snails), and occasionally eats small mammals, and other lizards. All animals need four things - food, water, shelter and a place to raise young. Unless you have leaky faucets or an abundance of Arthropods running around your home I doubt if that is why its coming into your home. In addition, your home does not provide a suitable place for raising young. So that just leaves one reason... it’s looking for a nice place to hang out (shelter). If you do not want it in your home, seal up any access such as under the doors.
