A common pest in New England which very few people have difficulty identifying is the queen carpenter ant. She is commonly found inside homes in the spring, wandering around like she owns the place, and is about as big as a Ford Fiesta. http://ehspest.com
Because of the queen’s considerable size (sometimes approaching 1 inch!), she is rather easy to identify. What many people don’t know is that there are different casts of carpenter ant, and although the queen is large, minor workers are only ¼ of an inch long. That being said, sometimes the small ants you find inside (even seasonally) may be indicative of a larger problem
This slide shows how to get rid of these pesky and damaging critters.
