Are you thinking of using insecticides during flower ? Dealing with spidermites during flower is a pain and not worth it, specially if the population is at a level where you can see webs. Youll just ruin your buds. Spraying and vacuum will not eliminate eggs and you will have feces as well - not to mention the most important, contaminated buds.
During veg, if you want to go nuclear you can use abamectin (which is organic - for whatever thats worth - no matter how much that hurts some ppl here lol) and it will solve your issues. Pyrethrins (without additives) are also good, and you can make your own with flowers or buy (without additives - pyrethroids etc) theres a good Daniel Fernandez video on youtube about it - you just have to inform yourself on their use specially if youre outdoor to not hurt wildlife. If youre indoor is easier to manage.
Both of these will solve a spider mite issue for good.
As prevention you can use nicotine (buy tobacco and soak in water). It works great as a deterrent.
Anywho, please dont vacuum mites in flower. Youre just leaving feces and eggs, and prob damaging the flower. And dont spray in flower either, If youre not talking about flowering phase, then disregard my comment 
Theres a good thread someone opened recently about dealing with spider mites with other methods than the ones i described, ill try to find it.
