Deer Defense in Southeastern PA & DE
We apply professional-grade foliar repellents at the right time, with the right coverage, on the right plants. The product bonds to the foliage and signals to deer that your plants aren't worth eating. Our program runs monthly through the spring and summer, with a dedicated winter service to protect evergreens through dormancy.
Foliar applications make your plants taste and smell unappealing to deer before they bite, not after.
Mature arborvitae and boxwoods can cost hundreds to thousands to replace. Prevention is a fraction of that.
Our seasonal program protects through the late-winter peak browse window and through the growing season.

Frequently Asked Questions
Arborvitae, yews, hollies, rhododendron, azalea, hostas, daylilies, tulips, hydrangeas, young ornamental trees, and most landscape ornamentals up to about six feet - the deer browse zone. Some plants (boxwood, blue spruce, ornamental grasses) aren't typically treated either because deer don't favor them or because product can affect the foliage.
Retail products typically last days, not weeks. The difference is product concentration, equipment that reaches the full browse zone, and consistent timing. Most homeowners can't sustain the cadence needed to actually break the feeding pattern.
Professional formulas include binding agents that bond product to foliage. Once dry, applications are rain-fast. If rain falls before dry-down, we'll come back and reapply.
No. The product works through taste and smell - deer simply find your plants unappealing and move on to forage elsewhere.
Yes. The active ingredients are food-grade or EPA-classified as minimum-risk. Once the application dries (usually within an hour), the treated area is safe for pets and children. We'll let you know when we're coming so you can plan accordingly.
Yes - when applied properly, on the right schedule, with professional-grade product. Independent research from the Connecticut Agricultural Experiment Station documented up to 93% browse reduction on treated plants. No method short of full fencing is 100%, but a well-managed program dramatically reduces damage.
