Deer present a problem for all forestry personnel and many garden owners. Their diets consist of not only herbs and grasses but also the tender shoots, leaves and bark of newly establishing crops. This presents an issue whereby game stocks need to be adjusted to reflect the natural capacity of their habitat whilst ensuring the woodlands remain healthy and productive.

This is not always easy. Although there are a number of remedies which include fencing and culling, these may not always be the most appropriate, especially if an estate abuts the woodland and they require the deer for commercial purposes. Therefore a different approach can be applied.

What is Trico®

Trico® is a completely harmless smell and taste deterrent based on emulsified sheep fat which deer will avoid as they find the smell and taste totally unappetising. It is approved for use as a deer repellent by the British Deer Society.

Trico® has been proven to give highly effective protection to trees, garden plants and agricultural crops against browsing. It has the advantage over other repellents on the market in that it has good rainfastness and is visible, thus providing effective protection against game damage during both the summer and winter. It is a ready-to-use spray and can be applied using PSP’s Deer Repellent Spraying Kit. The product’s efficacy has been proven in over 70 field trials and nearly 20 years of commercial use. TRICO® is registered in 21 European countries and North America and is considered the gold standard deer repellent.

Please note, Trico® contains a white dye. This enables spray operators spraying over large areas to see where they have sprayed. For ornamental plants or where you do not want a visible residue, use Trico® Garden here. It comes in a 500ml container and can be used with any sprayer, including our Duck handheld sprayer here. It has no white dye so will not turn your plants white!

    Just wanted to say what a great product the Trico Deer Repellent is.

    I own a small mature wood in the Yorkshire dales which has suffered in recent years from wind blow and ash dieback. In an attempt to diversify the range of species and make the wood more resilient I have planted a number of native species saplings over recent years, but have had little success due to the presence of deer.

    Last year I tried Trico for the first time (purchased from a previous supplier) and found it to be very effective and easy to apply, so I was pleased to find it is still available.

    What I especially like about this product are its environmental benefits, i.e. no need to fill the environment with plastic tree guards or carry out deer culling. Although I only used one application on the latest saplings I planted, the difference it made was very clear. In previous years the young trees I planted were killed when the tops emerged from the guards and fell victim to roe deer. This year the trees I planted and applied Trico to have all survived.

    A great product that saves money and the environment. I can’t recommend it highly enough.

    Works very well on our new sapling protection. We use it twice a year until they reach 1.2 m. You need to apply it when there’s no rain due so it sets hard like wax.
    The deer on our replant are mobile. Pest control is a hit and miss solution, as it’s often poorly implemented and the deer quickly repopulate from neighbouring properties. When spring arrives we have a short window in which to protect the new growth, that is when we use Trico. The deer don’t starve, they just move on to eat something which we don’t mind losing.
