The alternative for deterring browsing by deer, elk, moose and rabbits.

In Europe, hunters and foresters have long used sheep wool as a repellent against deer. However, its application is labor intensive, time consuming and the protection is short lived. Seeking to overcome these issues, Kwizda Agro sought an alternative and the idea of using ‘sheep fat’ as an active ingredient was born. Through our expertise and experience in developing effective and innovative formulations, Kwizda Agro took ‘sheep fat’, the active ingredient in TRICO® PRO and created an effective deer repellent.

Proven effectiveness and efficiency.

With more than 70 field trials, over 20 years of commercial use, and registered in 21 European countries and North America, TRICO® PRO uses natural ingredients to deter deer and other unwanted animals from summer and winter browsing, antler rubbing and debarking damage to agricultural crops, trees, shrubs, nursery seedlings, ornamentals and turfs. It targets the senses of taste and smell, producing long-lasting protection after a single application.

TRICO® PRO discourages damage by deer, elk or moose. Its dual mode of action creates both a scent and taste barrier. Residual repellency up to 6 months.

Formulated to start working upon application. Water resistant once dried. Dries odorless to humans. Long lasting protection with a single application.
