Adult mouse

5898  My name is Esther, I’m a single mom of 3 kids, 2 dogs, and 1 crested gecko. I had been hearing noises at night, but i brushed it away thinking it was my crested gecko’s activity since he is nocturnal, until i seen a rodent dash behind my fridge. I purchased glue traps and set them out,  In the past 3 days I’ve seen i adult rodent im assuming much larger then the ones ive captured. I’ve caught 3 rodents in my home, two identical in size and characteristics, 1 much smaller and different shape ears. My location is Los Banos California located in the Central Valley in California.  I was sure i had caught a rat the first 2 catches but the 32rd catch seemed the same in color yet it was much smaller and had larger ears. Could i have rats and mice?

This looks more like an adult mouse, such as a house mouse, than a young rat. See http://tinyurl.com/zkednfx   for some pointers on telling the difference. That aside, it is altogether possible to have both rats and mice; we have that situation on our property.  Ed Saugstad, retired entomologist; Sinks Grove, WV.
