Our Guarantee

We unconditionally guarantee that your insects will arrive in good health and will be ready to thrive in their new location (UPS delays and damages are beyond our control, however; mortality due to these circumstances is not covered.)
We are the only company to offer long-term assistance: Advice and tips regarding the release, establishment, monitoring, and future redistribution of our insects is included with the purchase of the insects–a service available at any time with no additional charge.
We will work on your terms. Within the constraints and availabilities of each insect, we will collect and ship to fit your needs. Your successful biocontrol program is important to us.
We are here to help you get the most out of your investment. Information and advice are always free. Let’s talk.

The successful establishment of introduced insects depends upon biological and environmental conditions beyond our control. We will provide you with information to help ensure the best possible outcome. However, we make no warranty about eventual establishment or degree of control obtained.

Shipping & Ordering

Ordering insects is as easy as calling 406-585-2789.

All insects are available during specific time periods, depending on their own life cycles. Since we fill our orders on a first-ordered first-served basis, it pays to order as soon as possible, especially for some insects with limited availability.

When you order, you will be given an estimated timeframe for the delivery of each insect. We will work within your time constraints as much as possible, but be prepared to receive the insects when we call—insects cannot be shipped outside their window of availability.

All orders must be shipped by overnight delivery and all shipments are coordinated with the customer prior to shipping so that you know they are coming. All insects are packaged in breathable containers in well insulated packaging. Packages are kept cool with frozen cold packs. We do not charge for our packaging.

We do not require prepayment. We enclose an invoice in each box as we ship. After you have released your insects to go to work at your site, you can mail a check to us.

Shipping charges are in addition to the price of the insects. BE AWARE THAT OVERNIGHT RATES ARE QUITE HIGH. At your request, we will provide shipping quotes for your location.

A Note About Permits

All of the organisms we sell are regulated. Federal regulations require permits for any interstate transport and release of weed feeding organisms. State level approval is also required. The person responsible for securing permits is the person who receives and releases an organism — our customers. For your convenience, we secure all required permits for our customers, as well as supply regulators with required follow-up information. Since it usually takes weeks to months to secure a permit, there is not time to do it after you have already received your insects. confirm with us that we are permitted for your state. A copy of the permit for your state of your obligations.

Why Use Insects to Control Noxious Weeds?

Exotic (non-native) weeds can be invasive. Introduced foreign weeds came without the successful co-evolved enemies present in their native ranges. Without these natural checks, the weeds are able to out-compete native vegetation. Introducing biological control agents can help to restore the natural checks and balances that control exotic weeds in their native habitats.
Biological controls are not a “quick fix”, but they are a permanent option for long-term management of invasive weeds.
Biocontrols do not eliminate the invasive species, but instead work to control the abundance and to minimize the monoculture characteristic of infestations.
The target weed will not be eradicated; instead the objective is to reduce the population to the point that it becomes just another “well-behaved member” of the existing plant community.
Biocontrol impacts the density and vigor of weeds, allowing native species to re-establish and more effectively compete.
The beauty of biocontrol is that it is self-perpetuating. Once the insects are released, they continue to reproduce and spread on their own. Collect them yourself after establishment.
Biocontrol insect populations will increase and spread to new areas on their own over time.
Biological control is most effective when used for large infestations of invasive species; however, it can also be a viable option for smaller sites.
Biocontrols are thoroughly researched before being certified and permitted, assuring that they will not attack crops or non-target species.
With proper planning and management, biocontrol releases can be an important component of integrated weed control, working effectively with cultural, mechanical, and chemical controls.
Biological weed control has been widely proven to be a cost-effective and viable weed control method, even for controlling widely dispersed and inaccessible invasive plant populations.
IWC’s approach to weed control incorporates integrated pest management principles to provide biological control agents and related services for achieving maximum benefits economically.
