We love our roses, but unfortunately there are insects every year that love them just as much as we do. There are some very common insects that have a tendency to snack away at our roses. If we are able to get a handle on them early on, we can eradicate them before they devour our roses. There are 10 most common little buggers.



1. Aphids, the most common one and the one we all cope with on a normal basis. These kinds of little buggers are tiny, pear-shaped pests that present themselves in colors such as black, green and red. They love to accumulate in thick piles on the new growth and on the flower buds. They will suck the nice juicy plant sap with their needle-like noses. They leave behind a trail of sticky, sugary material referred to as honey dew, which can become infected with a black and ugly substance known as sooty mold. Because honey dew is sweet, additionally , it may attract ants. Fortunately aphids are easy to manage. If you wish to do it naturally, powerful bursts of water from the garden hose will knock them off the plants although you need to do this several times. You may choose to spray them with an insecticidal soap. This soap will also eliminate the sooty mold. Roses also provide their very own natural way of helping out with bothersome pesky insects, a large number of very beneficial insects, such as lady bugs, have a tendency to accumulate on rose bushes and manage the aphid issues on there own, before significant damage can occur. One more choice is a product called Merit that has the ingredient imidacloprid in it which is fairly environmentally friendly. Malathion and acephate are common chemicals that work also. Make sure you always read the label and follow the instructions closely before implementing.



2. Spider mites are yet another common problem we all know much to well. Spider mites are very small minature spiders that you can barely see without some form of magnifying glass. If there are very many of them, you can see their incredibly fine webbing on the bottom of the leaf. Spider mite like to suck on the juicy plant parts also. The leaves little by little become a yellowish color with a shiny, silvery look to them. If not treated the plant will start dropping its leaves and will ultimately die. Spider mite tend to break out if the weather is very hot and dry in the summer months and on dusty plants. They will spread from plant to plant quickly so it is crucial that you treat them. You can control spider mite with insecticidal soap or summer oil, targeting largely the bottom of the leaves. A daily major, hosing down of the plants will help you to keep the spread of spider mite down. If they get completely uncontrollable, you might have to resort to use of miticide, for instance Avid.



3. Thrips are another almost invisible problematic pest. They feast upon flower petals which in turn causes the petals to become discolored, the buds come to be deformed as they open. Thrip have a tendency to favor the light-colored rose varieties. Insecticidal soaps are effective as well as insecticides such as acephate and Imidaclorid.



4. Rose midges as they are labeled, are another very small, almost invisible pest that feed on the new growth, specifically the flower buds, the flower bud shrivels up, turns black and falls off. The rose bush might look healthy, but then it just simply will not produce flower buds. Insecticidal soap can help a bit but this insect needs something more heavy duty in order to get rid of it. Use of Diazinon or chloropyrifos is required to attack the soil-borne larvae.



5. Rose stem borers are wicked tiny, worm-like larvae that bore into recently cut or the new canes and feed inside of them, causing the cane to die or become severely damaged. Beware, borer is often very, very difficult to manage. Look close at the infected cane and you will see a tiny hole where the bore have entered. Cut below this spot down far enough to get to the healthy tissue of the cane. Unfortunately if the borer have reached the base of the cane and bore themselves down to the bud union, most likely you will lose the rose plant altogether. Cutting off all injured cane is most likely your best method. Very few sprays on the market are effective, although you may be able get some of the larvae as they fall to the ground after feeding, by using parasitic nematodes near the base of the plant. To avoid the type of borer that enter thru the cut cane, an inexpensive and productive treatment would be to use elmers glue on the tips of every cane after pruning.



Then we have the beetle family. There are 4 that are most familiar that feed on other kind of plants but also love the juicy plant parts of the rose bush. Beetles are not easy to get rid of. They take flight and also have a smorgasboard as they go from plant to plant. Insecticidal soaps do help as does Neem and pyrethrum which control adult beetles. Chemicals such as carbaryl and acephate help also.





6. The June Beetles are about an inch long and are reddish brown to black. They generally feed at night. Turning the soil might help to expose the grubs to birds. Floral-scented traps that catch the attention of adult beetles can be purchased, but be warned, these kinds of traps may bring in more beetles than you had previously. Keep these traps at least 100 feet away from your roses if you decide to test them.



7. Cucumber beetles are about 1/4 inch long and are yellowish green in color with black stripes or dots on their backs. Two different kinds exist. They tend to take large bites out of the rose just as it is trying to open up.



8. Japanese beetles are 1/4 inch long and possess coppery bodies and a metallic green head. They feed on both flowers and foliage, often skeletonizing the leaves.



9. Rose chafers as their called, are one more beetle that are tan-colored with long legs.



10. Last but not least, the caterpillar, they occasionally feed on the foliage or flowers of the rose taking a lot of small bites. Caterpillars can be controlled with acephate and carbaryl sprays.
