we have beetle problems!! my husband and i have redone most of our landscaping and have found a ton of black beetles outside. we noticed some on the kitchen floor shortly after and killed them thinking we tracked them in. now we are finding them in our hallway and bedroom so we looked at them and they dont look like the beetles outside. do they look familiar to anyone? it is a very dark black, 6 legs, 2 antenna from the head and a seperate head and body. when squished the bum splits and its yellow/green. they seem to be driving my cat crazy!! any help would be greatly appreciated!!
