As we are a family owned business, social distancing is not a problem for us. We work primarily outside and speak with customers over the phone. Masks are worn when mailing packages.

Weedbusters Biocontrol, owned by Kandace and Bob Rich is a well established small business based in Missoula, Montana. We provide insects for the biological control of invasive weeds. With over 25 years of experience in natural resource management we have seen first hand what invasive plants like spotted knapweed, leafy spurge and Dalmatian toadflax can do to our native plant ecosystems and domestic livestock grazing lands. We have also been able to witness the spectacular reduction in weed density that biological control can provide.

At Weedbusters, we offer our customers the information they need to make important decisions on weed management for their property. Every landowner's situation is unique and we work with our customers to tailor a biocontrol plan that is best for them. We have supplied insects to many public land management agencies including the US Forest Service, US Fish and Wildlife Service, Bureau of Land Management, Montana Fish Wildlife and Parks as well as many local and county governments. However private landowners, with 1 to 15,000 acres of property have been the backbone of our business. No job is too big or too small for biological control. We will be pleased to provide you with references if you wish.

We guarantee the insects you get from us will be healthy and ready to attack your weeds, and if the insects are damaged in shipment we will replace them at no cost to you. At Weedbusters, we hate weeds as much as you do. We are eager to help you tackle your weed problem and begin to restore your property to what it was before the weeds came along. Give us a call to get started on your biocontrol program and put weeds in their place. We look forward to working with you.
