Help with pest identification

Looking for help to identify this sucker. I am in Maryland. We just built a house on a former corn field. These are getting into the basement and dyeing by the 100ís. Donít seem to be a pest. Just want to know if I should be worried about them or keep cleaning them up.

I've been searching "sawyer beetles" and "long horned beetles", which come close and it may still be one of those as they vary in coloration and shape throughout the geographic regions, but I didn't come up with anything close enough and in any case, finding large amounts of them inside is not typical behavior to my knowledge, but I'll stand corrected if otherwise.

I think these guys are harmless. A common route of entry when basements are mostly involved is them coming in from the exterior soil perimeter right next to the foundation, crawling up the foundation wall, over the sill plate and dropping into basement. This is common entry for millipedes, too.

Keep us posted.

For a more positive and objective ID, consider taking multiple specimens to the local County Agricultural Extension Agent. Proper ID is important and sometimes paramount in solving/preventing insect issues.

If my theory is correct, and you wish to do your own treatment, I would spray or granulate the soil perimeter of 3-4 ft out from the house. Focus on getting treatment right against the foundation wall where sometimes the soil pulls away from the wall due to settling and drying out. This is a common harborage for millipedes, beetles, earwigs, spiders, etc. Insecticides with an Active Ingredient of, but not in any order, that would be effective: Bifenthrin, Deltamethrin, Cyfluthrin, Cyhalothrin, Permethrin, Cypermethrin.
