I've used Sevin-5 Ready-To-Use 5% Dust on my chicken roosts and bedding for many years. The active ingredient was Carbaryl and contained 5% of it. They have now "updated" and changed the active ingredient to Bifenthin with just .1% of it. This Sevin Insect Killer Dust may be new and improved and I don't doubt it. I just want others to be aware of the change in case it makes a difference to them.
How Does Bifenthrin Work? (https://www.pedchem.com/blogs/news-articles/how-does-bifenthrin-work)
...It's a synthetic pyrethroid and mimics the naturally produced pyrethrums that are found in chrysanthemums. It works on contact and by ingestion and paralyzes the insect, causing death within minutes or hours.
When is Sevin not Sevin? (https://citybugs.tamu.edu/2018/02/14/sevin-not-sevin/)
In recent years, newer, more powerful pyrethroid insecticides have come to dominate store shelves, making carbaryl harder to find.
A couple forum links about Sevin Dust...

Thanks for the heads up, I used to use it more often. My wife barred me from using it in the gardens anymore (she’s more of an organic girl ;D) so I have switched to DE to sprinkle around in the bedding and roosts. I still use cattle pour on ivermectin and have recently started using a wormer solution from Victor since they discontinued Wazine as my parasite defenses.
