I may have made a stupid mistake.
Last year I found some wasps in the weep hole in my brick veneer house. The problem is that I didn't know what a weep hole was at the time, so I killed the wasps, filled the hole with Brickfix, and filled several others around the house to prevent the same thing from happening.
Today I learned what a weep hole is and realized that I filled a bunch of them in. I'm guessing I should go and clear them out, but I have no idea if I actually can get the Brickfix out.
How critical is it to clear these out? Will a chisel and hammer be sufficient, or is there a faster/easier way?
