Working In Harmony With Nature's Design. What Does This Mean?

Shop Home & Garden

From the beginning, Contact BioSolutions has been extremely aware of the potentially damaging affects of conventional weed control chemicals. These chemicals can impact the soil, the environment, the plants, the animals, and the people. For this reason, we started developing a consistently effective, non selective bioherbicide. FireHawk bioherbicide lawn weed control spray for home lawns and gardens enables us to manage weeds and unwanted vegetation while simultaneously minimising residual activity in the soil.

The mode of action for FireHawk Bioherbicide is desiccation by dehydration. By using cutting-edge technology to combine the organic acid, nonanoic acid, FireHawk weed control is able to break down the waxy protective surface of the treated plants or weeds. This causes all of the nutrients and moisture from the plant to escape and it dies. Subsequent applications, in some cases, are required to deal with the seed bank of the weeds in the soil.

FireHawk™ Bioherbicide is an excellent choice for fast-acting and effective weed control around your home and garden

Reducing or eliminating weeds in your backyard, lawn, or garden requires a paradigm shift in thinking. Traditional chemicals may seem cost-effective, but they could be injurious to soil-health and can establish an environment where weeds will thrive.

FireHawk Bioherbicide stands as an alternative, yet equally effective, solution to conventional chemical herbicides. It effectively eliminates unwanted weeds while reducing residual activitiy in the soil. FireHawk Bioherbicide can help create a more resilient, thriving landscape with fewer weeds over time.


Whether you're maintaining a lush lawn, growing a home garden, or keeping your backyard weed-free, FireHawk Bioherbicide provides an effective home weed control solution.

What our customers Say

"When I found out about Contact Organics I was excited to try a truly clean weed killer that would be safe for my family and pets to be around. My hope was that it would really work since so many other natural weed killers failed to provide successful results.This product worked instantly on our weeds around our house and in our gravel driveway.  We were amazed with the results so we haven’t used any other product since.  I believe in this product so much that I tell everyone I know about it!  Next, I hope that our community will start using it instead of dangerous chemicals that are harming our families and food supply."
