Tunneling in the Mortar ??

utterlydiy · 13 May 2015

Noticed today, something is tunneling into the mortar in my porch.

The tunnel is about a pencil diameter, approx. 20mm deep and just under the Damp course felt with some dust from the hole on the floor.

What is it and how do I treat it.

Thanks

Sounds like a masonry bee to me. They are solitary and do not have a hive, but like soft mortar, particularly on a south facing wall (because it is warmer). Into which they tunnel to lay their egg, I had loads when I first moved into current house and needed an exterminator to spray them, but if it is only one then fly spray will probably do it, then repoint.

Done a search, most say it could be Bee's or Ants.

But not seen any Bee's or Ants around in this area.

thanks

Whatever it is, fly spray will probably kill anything in there.
