Permethrin-based Sevin use

[mbowman]

Are most users satisfied with results when treating nest cavities with the new (permethrin-based) Sevin formulation?

[Bird Brain]

yes. The new Sevin worked great for me.

Thank you.

Curious the responses on this thread, the new formula gets hammered on the FB pages, but really doubt any of those folks have every actually used it. Heck, the old formulas was frowned upon by a lot of folks.

I used the new Sevin formulation last season at my colony and had the worst mite infestation I've experienced at my site in a decade. Not sure if it was due to the year's weather or the new formulation. It was an extremely dry season at my site last year and would suspect a wet season would have more of a negative impact on effectiveness of the Sevin than would a dry season. Nonetheless, I will try it again this season and see if I experience better results. My colony has too many nests for me to conduct nest changes.

In addition to sprinkling Sevin dust under my pre-nesting material, in past year's I've used a permethrin-based "chicken safe" mite spray on the outside of my martin housing, sprayed directly onto the crawling mites if the infestations got to be problematic later in the nesting and brood rearing season. I've never sprayed directly on birds or inside nest cavities. It seemed to help reduce the pest numbers, but did not have a residual effect on mites so I would need to reapply weekly. I didn't like that chemical option, so last year I tried a Dawn dish soap spray solution (3 Tablespoons per gallon of water) and had similar results as with the "chicken safe" spray. I use a hand misting bottle to apply the Dawn solution to the outside of the housing and gourds and the mites would die on contact. Again, there is no residual effect on mites with the Dawn soap solution, so I would need to reapply bi-weekly or weekly to get ahead of the infestation during the later part of the nesting season. I would also remove gourd lids and spray the inside of the lid if mites were present there, which they usually were. I will use the Dawn soap spray solution procedure again if another mite infestation occurs.

After the nesting season last fall when I cleaned out my nest cavities, I soaked each of my plastic gourds in a 5-gallon bucket of the Dawn soap solution for 5 minutes to kill any remaining mites. I prefer using this solution compared to a bleach or alcohol-based cleaning solution.

Your numbers are huge! I would love to see pics of your site. Thank you for caring for and fledging so many Martins.

Thank for your response. I do not know how helpful cedar shavings would be in resisting mite infestations.

Thank you very much for this information.

I still have some of the old Sevin with carbaryl left. Bought a bunch before they changed over, works great. When I run out I’m going to try this “southern ag”. Seems close to the same best I can tell….
