I have fine webs in my Italian Cypress. What kind of insect does that? What can I use on them?
There are a many pests which like to nest on Italian Cypress and many that will build or form some kind of “web”. The first and most obvious would be spiders. But their webs are usually structured and well designed. They use distinct patterns and in general, are easy to identify. Also, I wouldn’t describe their webbing as “fine”. Most important, they’re not a threat to the trees so you’re seeing spider webs, I wouldn’t worry.
But other pests like caterpillars or spider mites would be reason to treat. There is a wide range of caterpillars which will target cypress trees. Some are small and hard to see, kind of like a gypsy moth. Others are large like army worms or tent caterpillars. With this kind of problem, you would be able to see the caterpillars easily and they would be distributed throughout the tree foraging and eating most any time of the day. This feeding is damaging to the plant and ultimately could lead to disease and other issues.
More common on Italian Cypress are spider mites and if you’re not able to see any pest then you may want to take a closer look for these little guys. I have found using a blank piece of white paper helpful when looking for them. Just take the paper to the tree and hold it under any branch where you see the webs. Next, run your hand over the foliage and shake the branch a bit all the while holding the paper underneath the branch your moving. If there are mites on it, some will show on the paper.
Now there are many species of spider mites and several will form fine webbing. Most all mites are a threat to any plant they infest and should be treated using one of the methods described in our spider mite article here:

In the article you’ll learn about many products but for Italian Cypress, we’ve had great success using a combination of BIFEN and SPREADER STICKER. Use it twice a month for two months and the problem will be gone. 1 oz of Bifen and 1 oz of Spreader Sticker per gallon of water will be plenty strong and you should expect to use 1/2 – 1 gallon of mixed solution per tree (depending on tree height).
