I have black flies on Rose bush. There were greenfly on it and I sprayed it with Rose clear and they seem to have gone but have been replaced with black ones instead. Are these another type of pest or is it just the dead greenfly?



Aphids come in various colours, black, green and white being the most common. Depending on which Roseclear you used, the effect may have been temporary, or last up to two weeks. Check the bottle to see how often you need to spray.
