one of my "stripeless"garters is growing to look like one in your heat lamp baiting operation
i assumed they were just abberant easterns but there looking a little different,i will try n get a pic of her up soon to compare.

mine still have faint stripes but the female is very brownish and starting to look like what you have crawling outa your concrete
