I'm curious to know what the cost is to do more treatments at a lower kill
rate, as opposed to fewer treatments at a higher kill rate. Any idea what
the difference in cost is?

I'm also curious as to what impact that has on your viral loads. While a
lower kill rate is more likely to reduce pest resistance, wouldn't it be
more likely to maintain a higher viral load in the mites that survive?
Thoughts on that?
