About Our Company

GR Technologies is where Science and Technology come together. Captain Bob's Amazing No See Um Repellent is made from all natural, organic, plant based products.  We grow our own Lemongrass, Rosemary and Guanabana Trees that we extract the essential oils from. This not only gives our products a longer shelf life but it strengthens the overall effectiveness as well as adding a fresh, tropical scent to the finished product.

At GR Technologies we work hard at staying on top of the latest research in the Organic Repellents Industry.  All of our products active ingredients are thoroughly tested for effectiveness, longevity, contaminants, purity and combined mixture shelf life.  We make our products in small batches and we personally test every batch.

innovative products, created with the greatest degree of precision and care.
