Key Information: Insects rarely get transported inside on decorations. DO NOT treat your decorations with insecticide. This is potentially dangerous to your family and pets. Don’t worry. Most of the insects that hitch a ride on decorations are harmless. A surprise, six-legged guest is the last thing most people want to deal with during[Read More…]
Northern red oak (Quercus rubra) is a Midwest native and is generally well adapted to growth across much of the region, but we get questions about dieback or ‘flagging’ on it fairly regularly. The two most common causes of twig dieback on this host are Kermes scale (Allokermes galliformis and A. kingii) and fungal canker/dieback[Read More…]
Now that fall has arrived many people have begun collecting next year’s firewood and clearing their yards of brush and downed trees. This can be a great way to both tidy up your property and save some money but there are a few pitfalls to avoid. Already dead trees or dropped limbs can make easy[Read More…]
Wandering fall caterpillars promise the presence of pollinators, bird food, and flashes of fluttering color in your yard next spring, but overly enthusiastic yard cleanup can make you lose out on these benefits.

The entire Midwest just experienced one the worst fall armyworm (Fig. 1) outbreaks in decades, but for turfgrass professionals and enthusiasts, it’s not over yet. These seasonal, but sporadic insects made their appearance at the end of August, decimating lawns and other managed turfgrass. But, now that the damage is done, our focus shifts from[Read More…]
Bright yellow or orange aphids covering a milkweed plant may look shocking, but they usually aren’t a cause for concern. These aphids become more noticeable in late summer or when plants are stressed. Some may find them unsightly, but, for the most part, they cause little to no harm to plants or beneficial insects on[Read More…]
Dead leaves covering trees (image 1) or on the ground beneath them (image 2) in July would normally be a worrying sign for tree health, but this year much of the damage can be blamed on 17-year cicadas. This damage is unlikely to cause serious trouble for healthy, large trees and management is relatively simple.[Read More…]
Whether it be a hail storm, late frost, or an early season pest, springtime is when Mother Nature tests the patience of even the most experienced gardeners. While many gardeners have learned the hard way not to plant during a warm spell two weeks before the frost-free date, many more are unable to resist the[Read More…]
This past February was among the coldest and snowiest we had since 2014. Yet despite our discomfort, it won’t be an issue for most insect pests that attack landscape plants. Most species regularly survive winters that are far colder. Indeed, the snow cover probably protected many insects from freezing in this year’s winter weather. Insects[Read More…]
