⚠️ Ohio homeowners with boxwood plants need to watch this!

The Box Tree Moth (Cydalima perspectalis), also known as the Boxwood Moth, is an invasive pest originally from East Asia that is now threatening landscapes across Ohio — and it's spreading fast.
 
In this week's video, Adam Fintak, Master II Service Expert at Oasis Turf & Tree, breaks down everything you need to know about this destructive invasive insect, how to identify it, and what you can do to protect your boxwoods before it's too late.

Heavy infestations of the box tree moth caterpillar can lead to the complete defoliation of boxwood plants — stripping them entirely of their leaves and ultimately killing them if left untreated. Because of the severity of infestations being reported across our region, the Ohio Department of Agriculture has issued an official quarantine in six Ohio counties.

Boxwoods are one of the most popular and widely planted shrubs in Ohio landscapes — used for hedges, borders, foundation plantings, and formal garden designs. Losing them to an invasive pest can dramatically impact the look and value of your property. Don't wait until you see damage — by the time defoliation is visible, the infestation is already severe.
