tiny white balls on rosemary bushes
How to get rid of tiny white balls (looks like minature cotton balls) on my rosemary bushes. When cut open, there is a tiny bug!
It sounds like you have either mealybugs or possibly scales, which are closely related to mealybugs. These insects form a cottony mass on the lower sides of branches. Both are usually controlled with horticultural oil sprays. Neem oil is also effective. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
