Deer Defense in Southeastern PA & DE
Deer pressure in Chester County is among the highest in Pennsylvania, and your landscape pays the price. Our Deer Defense program protects the arborvitae, boxwoods, hollies, hostas, and ornamentals you've invested in - using professional-grade foliar repellents that are safe for pets, children, and pollinators. We build custom programs around your property, plants, and the deer activity in your area.
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.

Deer Defense Program
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 standard program includes four to six applications timed to deer feeding patterns, from late winter through fall.

DTL Deer Defense Applications
Our program is built around the deer browsing cycle in Southeastern PA. A typical program may include:
- Late Winter (Feb–Mar): Bridge application during the peak browse window when natural food is scarcest.
- Early Spring: Protect new growth, candles, and flush leaves as plants emerge from dormancy.
- Late Spring: Coverage for hostas, daylilies, hydrangea buds, and other high-pressure plants.
- Summer: Maintenance applications every 4–6 weeks during active growing season.
- Fall: Foundation application before deer establish winter feeding patterns.
- Late Fall: Long-lasting winter formula to protect evergreens through dormancy.
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.
