In my experience, I don’t get mites and most pests if I don’t take plants from other gardens into my own garden, and I definitely never take plants inside that were outside whether cannabis or other plants, so I never have had aphids either, worst I get is a fungus gnat or maybe 2-3 in the whole grow but I am in organic soil, and they seem to die off before becoming an issue of any kind luckily
but also don’t let your room/tent get too hot, as the pests love warmth and humidity, and it can be avoided with some proper airflow to deter the bugs by having your leaves slightly moving in the breeze, and not providing perfect conditions for them to thrive in as well
but if you got them this badly already I’d suggest predatory insects over spraying anything in flower at all…
