If you are having problems with your roses, insects may be responsible. They can do a lot of damage if you do nothing to chase them away. Here is an overview of ten creepy crawly enemies of roses and some ways to identify them.
Aphids are the most frequent problem pests. They like to make themselves at home in the growing tissue of roses (buds and shoots). Low or even moderate levels of aphids will pose little threat to your roses, though you will need to keep a close eye on how they spread. High numbers of aphids produce an excess of honeydew, which will encourage the growth of mold and they will eventually blacken the rose leaves.
