How far into flower are you? Early into flower I'd recommend a cycle of Azamax and if you're not comfortable with that there are some soaped based solutions. They are some invasive mofos, they love catching rides spreading their love. I've actually had to use Azamax late into flower with no negative results, I just washed my buds before drying! 

Ladybugs are good but first I'd watch a video on creating the right environment so they live long enough to do the job also find ladybugs that come with the packet of attractant you mix with water.

I've also used a water/isopropyl alcohol mix to instantly kill them then I followed up by rinsing the plant with water in my 2 gallon sprayer. I waited a couple days then repeated.

I've also read people reverse wrap tape around their fingertips and concentrate on the underside of the leaves getting them stuck to the tape!

I just smoked so message me if I don't make sense, lol!
