TyraTech Announces U.S. Registration of New Insect Repellent Product NO-SKEETO!™ 

Field Trials Demonstrate Superior Performance Over Current Market Leading Products

TyraTech, Inc. (AIM: TYR and TYRU), a natural life sciences company, is pleased to announce that the Company has been granted registration for its new personal insect repellent NO-SKEETO!™ in 49 States and the District of Columbia. This means that the product is approved and ready for immediate commercialization in retail channels. NO-SKEETO!™ features TyraTech's Nature's Technology™ platform which harnesses the power of natural ingredients to deliver best-in-class efficacy and family safety.  

Both Laboratory and Field trials have demonstrated that NO-SKEETO!™ significantly outperforms 15% DEET for both mosquito and tick repellency. Trials have been carried out using various species of mosquito including those which are known vectors of West Nile Virus, Malaria, Dengue fever, yellow fever and St Louis encephalitis. Tick trials have included species which are vectors for Lyme disease, Rocky Mountain spotted fever and Southern tick associated rash infection (STARI).

The Company is currently in the process of evaluating global commercial and retail partners for this product.

The Company has also filed for patent protection for its NO-SKEETO!™ formulation and has submitted data from the laboratory and field trials for publication in two international journals.

TyraTech's Vice President of Research & Development, Dr. Keith Kennedy, said: "Diseases transmitted by mosquitoes and ticks continue to be an increasing problem in North America. The number of West Nile Virus cases reported in the US so far this year was the highest number recorded by the Centers for Disease Control in the last 10 years and the incidence of Lyme disease continues to exceed more than 30,000 cases per year. We are excited that we have been able to develop a highly effective natural alternative to the products currently available without the unwelcome side effects associated with DEET. This also further evidences TyraTech's ability to turn its technology platform into exciting and, what we believe to be, high value products".

TyraTech's Vice President of Commercial Operations, Shayne Wetherall, added: "NO-SKEETO!™ provides a compelling and timely solution for families seeking superior non-toxic protection. This product also provides TyraTech with outstanding commercial opportunities as it is ready for immediate commercialisation. We are currently in the process of evaluating global commercial and retail partners for this product and for our strong pipeline of personal repellent solutions".
