chicken house fumer

Hi to all you knowledgeable chicken people, I don't often post anything on this site as the information already on it is rather useful. However, has anyone ever used 'Chicken House Fumer" from the Poultry Keeper range, and was it effective?

Really enjoy this forum and will continue to use its vast knowledge   

I've used the poultry fumer and find it very effective as a quick kill, but as Joyfull says, it still pays to spray everything with poultry sheild as a backup. I use a fumer that's meant for a bigger coop than mine so it doesn't really matter if it's not air tight. However, you must make sure it's thoroughly aired before you put the hens back in.

Funnily enough, had to use a fumer today as I discovered the dreaded red mite yesterday. After the two hour wait I checked the coop and what this new one seems to do is draw all of the mite out onto the walls. Most were dead and the rest had a liberal spraying of poultry shield. I'm just waiting for it to dry out before I paint a DE slurry on everything.
As for locking them out - there was a queue by the temporary nest box I've placed by the coop door - a very large deep cardboard box on its side with a smaller box inside. So far I've taken 12 eggs out and there's still a queue!
