Five pages to start. Each one is tied to a Kansas or Johnson County record — not a national pest brochure with “Kansas City” dropped in.
These pages sit under tree and plant health care. They are not in the main navigation. If you already know the problem, jump in. If you do not, send a photo to the shop and we will tell you which page matches — or that it is something else.
Insect · Agrilus planipennis
Kansas confirmed emerald ash borer in Wyandotte County in 2012. As of October 31, 2025, the Kansas Forest Service is at 19 counties. If you still have a green or white ash in Johnson, Wyandotte, or Leavenworth County, the beetle is not a future problem. It is already in the woodpile.

Disease · Bretziella fagacearum
Overland Park confirmed at least three oak wilt cases in September 2025. Two of them were at the Indian Creek Recreation Center. Pin oak is still the city’s official tree. That is a bad combination.

Disease · Bursaphelenchus xylophilus
If a Scots pine in eastern Kansas goes from green to brown between August and Christmas, it is pine wilt until a lab says otherwise. K-State has been writing that sentence for decades. We have been cutting the trees.

Insect · Thyridopteryx ephemeraeformis
K-State told Kansas homeowners in May 2026 to start scouting bagworms in early to mid-May. If you wait until the bags look like brown ornaments in August, the caterpillar has already sealed itself in and the chemical cannot reach it.

Disease · Apiognomonia veneta
Every cool, wet May we get the same call: “The sycamore dropped everything. Should we take it down?” Most years the honest answer is no. K-State still calls sycamore anthracnose the most serious anthracnose in Kansas. Serious is not the same as fatal.
Open the sycamore anthracnose pageDutch elm, Hypoxylon canker, Japanese beetles, and iron chlorosis on pin oaks are already on the list for later weeks. We are not dumping 30 thin pages in one day. Each new entry needs its own Kansas source, its own photo, and a reason a homeowner in this metro would search it.
