Not clinkers... Stink bugs! My house has 3 separate chimneys- 1 for the 30 and 2 other fireplaces- we rarekly use the fireplaces and depend on the 30. Now that it's warming up the little feggers are coming out of both fireplaces. I haven't seen them in the 30 yet but I did last year. First option seems to be to light a good fire in each flue. Trouble is it's like 70 out, so a good fire is at best undesirable, and difficult to get going. Second option seems to be to open each damper, toss a Raid fogger in, close the damper, and leave. The voice in the back of my head is whispering, "bad idea" but I don't know why. Anyone else having trouble with these guys? How did you get rid of them?
