The second picture looks like aphids to me , not sure about the first, sorry.
Looks like Thrips damage to me. In heavy infestations, you can prune out the worst affected areas. If it's a large area/shrub, blast the shrub with a hose on jet setting. Try to keep the base of the shrub and surrounding areas cleared of dead plant material. Sometimes, they over-winter causing further re-infestations.
