Thanks for looking over my question.
I wanted to know if Fluvalinate Strips for Varroa Mites are safe and effective. From looking at the price differences between Fluvalinate Strips and some of the others, I'm guessing Fluvalinate Strips has some issues, but I wanted to check here. I am aware they come from China as well. I did google the topic, but I was not able to get a clear answer.
I'm also looking at using Oxalic acid, but for the cost of the Fluvalinate Strips (20 strips for $3.99 /eBay) I thought I see if they are a viable option.
