De Groene Vlieg (The Green Fly) is a private and independent company with nearly 100 employees. We focus on pest control in open field agriculture and horticulture via the application of biological agents (sterile insects, parasitoids, and predators), soil sampling & analysis and monitoring of agricultural pests at individual field level. We aim to apply the most environmentally friendly methods. Our main fields of play are the Dutch market and its adjoining regions. We work independent of farm policy (conventional or biological) and all our services are tailored to the individual wishes and needs of our clients.
