    I'm voting to close this question as off-topic because we are not entomologists on this Stack! – ThreePhaseEel Feb 15 '16 at 3:30
  • Off topic? I'm not asking for its Latin name, just generic type: termite, carpenter ant, wasp, etc. I'm only asking so I can know if it's a potential hazard to the house (wood damage). – Michael Feb 15 '16 at 4:26

Looks to me like a mud dauber wasp nest, not egg pod. Mostly harmless to your house, though the nest may trap a bit of moisture; you could knock the nests off during the winter if so inclined, or when they'te no longer occupied. Mostly harmless to the occupants too; these are fairly polite wasps.


I think it is on topic as the OP said worried about dammage. If you are in the U.S. most counties have an extension office or extension service office. (That’s what they call it here anyway). I have taken both plants & critters I could not identify. The plant turned out to be a poisonous broad leaf plant (they came out and killed the plants for free). The bug was a type of boring beetle not native to this area and they came out and put up a bunch of traps in the area that I found it in and arround the neighborhood, again for free. I recieved a letter about 6 months later saying the beetle could not survive our winters and they had identifyed the truck it came in on from Mexico.
