Spider mites are a common pest in Northwest Ohio and Southeast Michigan; there are multiple species. They can be controlled and do produce silken web material like a spider, which they are related to. Due to their size, they are often overlooked. Using a white piece of paper under the suspected infected branch, shake the branch. If you see small black, brown or reddish 'dots', you may have spidermites.
The damage first appears like lines of yellow dots on the leaf of the plant (from spider mites feeding on the plants cell and killing portions of the leaf or needle). During heavy infestations, whole leaves may be stripped and killed. If they spider mite population is minimal, treatment may not be needed.
