First time posting here.This morning I was inspecting my house and found these two holes next to the foundation.

My friend suggested to insert a stick to see how deep they are.

Any ideas or suggestions on how to approach this? Not sure if I should be concerned.

Also you'll notice pieces of concrete around the foundation. That's because I attempted to seal the house holes I could find along the foundation in summer time when we first moved in and didn't clean it up.

Thanks in advance for the help!

    Some kind of insect? They're the right size for hornets but they usually make more of a mess around the hole.

  • What part of the world are you in? I'm not sure this can be answered without a little more information or context.

  • Sure, sorry about that. I'm in Connecticut, temperatures lately have been around 57 degrees at night, 70's during the day.

  • Install one of those wildlife cameras near the holes and see if anything comes out :)

Did cicadas emerge this year in your area? These look like cicada holes, which are made when the cicada emerges from the underground stage of its life cycle in search of a mate. If this area is shielded from rain, the holes could have been there since mid-summer, when cicadas typically emerge.

If these are cicada holes, there's nothing to do but clean up. Cicadas don't return to the same hole.

  • Could be cicada killer wasps too. But those hang around a month or two and are hard to miss. (They’re very large)
