Re: prophylactic mite tx's?
Since there does not appear to be any treatment that is 100% effective in eradicating mites with one treatment, and since mite propagation is an exponential/geometric progression, then treating early is more effective than treating late.

If you wait until you have 50,000 mites, you'd still have 5,000 left and within two or three cycles their levels are back to critical, and your hive is probably dead or absconded or left so crippled and sick that they don't make it through the Winter.
Treating early is far better than treating late.
However, it costs time, money and effort to treat, so some people wait for a particular threshold of mite level to occur in order to balance costs.
You need to decide for yourself what level of infestation you are willing to tolerate in order to make your investments of time and money acceptable to you.
In my book, that ounce of prevention (or whatever two strips of MAQS weighs) is worth far more than pounds of cure.
If you want to be successful, study successful people and do what they do.
