How is DeerPro Winter Animal Repellent different from other repellents?

Most over the counter deer repellents smell bad and dissipate quickly. They need to be re-applied every 10 days to two weeks and after it rains. It is also difficult to spray repellents in the winter due to freezing temperatures, snow and ice. DeerPro Winter is a professional strength deer repellent that will protect plants all winter with just one spray in the fall. It is the best working, longest lasting deer repellent on the market.

How does DeerPro Winter work?

DeerPro Winter is a strong taste deterrent. It tastes so bad the deer will not eat treated plants. During the winter, freezing temperatures suppress the smell and effectiveness of most deer repellents. You need to use a strong taste deterrent during winter months.

DeerPro Winter is more expensive than other repellents. Why should I use it?

Because one spray in the fall will protect up to 6 months, DeerPro Winter is actually a much less expensive product to use. The savings in material and labor make it the most cost effective deer repellent on the market.

What is the active ingredient in DeerPro Winter?

The active ingredient is Thiram, a fungicide that has also been used as a repellent for many years. It is the only ingredient we have found that will keep hungry deer from eating evergreen trees and shrubs during the winter months.

Why does DeerPro Winter leave a residue on the plants?

The active ingredient in DeerPro Winter is white. We have added a colorant to tone down the look of the spray, but you will still see a noticeable coating on broad leafed evergreens. The residue will break down in the spring.

How long have you been using DeerPro?

DeerPro Winter has been protecting expensive landscaping from winter deer browse damage for nearly 40 years.

Why can’t I buy DeerPro Winter in the store?

DeerPro Winter is a professional strength deer repellent that is intended for use by licensed plant care professionals. Unlike most deer repellents, DeerPro Winter is EPA registered and conforms with strict environmental safety standards. If you’re a homeowner, contact us to find a licensed professional in your area!

Can I use DeerPro Winter during the growing season?

No, DeerPro Winter can only be used as a repellent from October 1st to the end of March. During the growing season you need a smell deterrent to keep up with new growth between applications. For protection of annuals, perennials and deciduous trees and shrubs you should use DeerPro Spring/Summer.

Does DeerPro Winter protect plants from more than deer?

Yes, DeerPro Winter also protects trees and shrubs from rabbits, mice and other rodents. DeerPro Winter also acts as an anti-dessicant spray protecting plants from winter burn.
