Say No to Neonics: What They Are and Why We Should Care

by Katelyn Rinicker | Aug 5, 2024

Neonicotinoid pesticides are detrimental to not only monarch health, but all pollinator health. If you have never heard of Neonicotinoids, or Neonics for short, and aren’t sure why you should care, I urge you to keep reading.

What are Neonicotinoids?

Neonics are a type of pesticide that attacks insects on a neurological level. This means “the way they work is by permanently binding to the nerve cells of insects, overstimulating and destroying them. Exposed insects often exhibit uncontrollable shaking and twitching followed by paralysis before eventually dying” (Lindwall, 2022). These pesticides are used in a variety of ways including on agricultural land, golf courses, lawns, gardens, and even in tick and flea repellents for our pets, making Neonics the most used pesticide in the USA since its development in the 1990s (Lindwall, 2022). I know how they affect insects and I’m not sure I’d want my little furballs anywhere near it.

Why should we care?

Neonics are applied to soil around a plant’s roots or, even worse, as a coating on a plant seed (Lindwall, 2022). If it is applied as a coating to a seed, the plant absorbs it as it grows. This means that the whole plant is now toxic to any insect that tries to have lunch (Lindwall, 2022). The sweet nectar, pollen, leaves, stems, and even fruit are not safe for insects to pollinate or munch on. “In large-scale studies in the UK, agricultural applications of seed-coated neonicotinoids were found to be associated with decreased abundances of bees and butterflies” (Van Deynze et al., 2024). Even when neonics are applied at nonlethal doses, they can weaken critical functions, such as an insect’s immune system, navigation, stamina, memory, and fertility (Lindwall, 2022). So if the chemical doesn’t outright kill the insect, it prevents it from reproducing and significantly decreases its quality of life.

Neonics are also extremely harmful to pollinators. They are non-selective, which means that all insects are affected by them. “Since their introduction, neonics have made U.S. agriculture nearly 50 times more harmful to insect life” (Lindwall, 2022). “Almost 45% of the 3374 articles on neonicotinoids published to date … addressed the issue of negative interactions of neonicotinoids with bees and other pollinators” (Jactel et al., 2019). There are so many articles on the internet that address neonics and call for a change in pesticide use. During a 17 year study on butterflies and neonics, it was found that the diversity of butterflies and abundance were negatively affected and declined (Van Deynze et al., 2024). It is thought that these pesticides may have triggered the decline of butterflies in 2003, when treated soybeans became available in the Midwest (Van Deynze et al., 2024). Butterflies aren’t the only pollinator affected by this nasty pesticide. Beekeepers have reported that more than 45% of their honeybee colonies have been lost between 2020 and 2021; this is the second highest colony collapse rate on record (Lindwall, 2022). That’s not all, Iowa is the home of over 4,000 native bee species including the already endangered Rusty Patched bumblebee. This means that all pollinators are at risk due to these chemicals.

This graph from Van Deynze et al. shows the correlations between pesticide use and the decline in monarch butterfly (D. plexippus) populations throughout the years.

So maybe you don’t care about some bugs. Well, it’s affecting people too. When applied to the soil around a plant, only about 2% – 5% actually get on the target plant, with the rest becoming residue on the soil outside of the plant’s root system’s reach. This residual pesticide then gets washed away by irrigation or rain into our waterways. These are areas we let our children swim and play in. These are areas we are fishing in. These are areas we live by and see daily. A 2015 study by the U.S. Geological Survey found neonic pollution in more than half of the streams it sampled nationwide (Lindwall, 2022).

Don’t worry, we can still do something to help!

In 96% of cases, neonics can be replaced by alternative pest control and even better, in 78% of cases, at least one non-chemical alternative method can be used (Jactel et al., 2019). You can buy organic seeds to plant or check that the seeds you are using haven’t been coated in this liquid death for our insect friends. Planting more safe gardens with plenty of blooming plants is a great way to support pollinators. Growing milkweed is not only essential to monarch survival, but will attract bees and other insects as well. Even if you are in an apartment, you can help out! Growing some beautiful native plants like Hoary Vervain (Verbena stricta) or Butterfly Milkweed (Asclepias tuberosa) in a container garden on your balcony or patio are great options if you don’t have lawn space. Making sure that you have blooming plants in Spring, Summer, and Fall is essential to pollinators survival.

Ames Pollinator-Friendly Practices Pilot Project Completed

by Mike Kellner | Nov 3, 2022

How can homeowners in Ames be encouraged to increase pollinator-friendly practices in their yards? That was the question addressed by former Prairie Rivers of Iowa Lincoln Highway Heritage Byway Coordinator Shellie Orngard in a recently completed pilot project using Community Based Social Marketing strategies. Now that the pilot is completed, the project will move forward in 2023 to explore ways to apply what was learned to increase pollinator habitat along Iowa’s Lincoln Highway Heritage Byway.

Community Based Social Marketing was developed by Canadian psychology professor Doug McKenzie-Moher, author of Fostering Sustainable Behavior. It is used in developing and implementing community programs that make use of scientific knowledge of human behavior in effecting change. Community programs such as composting and conserving water and energy have used it to increase participation.

According to the Iowa Department of Natural Resources, 70 to 80 percent of Iowa was once covered by prairie, producing rich agricultural soil and a lush environment for pollinators. Now, with 90 percent of Iowa’s land in agricultural production, less than one percent of Iowa’s prairie remains, simultaneously reducing pollinator habitat. “Doing this project I learned strategies to encourage pollinator-friendly practices that can be employed along Iowa’s byways,” says Orngard. “We are now exploring applying these strategies to make the Lincoln Highway Heritage Byway a pollinator-friendly byway from the Mississippi to the Missouri Rivers. Some of Iowa’s other 13 byways have also expressed interest.”

While a number of groups (including Prairie Rivers) have focused on encouraging farmers, other large landowners, and local governments to improve pollinator habitat, this project will also include urban areas, businesses, and homeowners.

An initial survey was conducted to determine the perceived barriers and benefits of creating a pollinator garden. The results show that homeowners can face some big barriers such as knowing what types of plants to grow that provide diverse and useful habitat during all seasons. Additionally, by implementing pollinator-friendly practices, homeowners may, in some cases, go against societal norms of having a yard consisting primarily of well-groomed turf.

This project focused on strategies to encourage a paradigm shift in what landowners consider desirable, resulting in such practices as reducing pesticide and herbicide use, letting grass grow longer before mowing, and leaving leaves for overwintering insects.

To encourage year-round pollinator-friendly practices, Orngard worked with Xerces Society Farm Bill Pollinator Conservation Planner/NRCS Partner Biologist Sarah Nizzi to create The Pollinator Friendly Yard: A Seasonal Guide informational flyer. Homeowners were asked to commit to increasing their pollinator-friendly practices according to their comfort level.

As a final strategy, Orngard worked with local artist Naomi Friend to create a charming yard sign homeowners can use to educate passersby about why some leaves are being left to provide habitat for overwintering insects.

Orngard summarizes the pilot project as a success that will guide Prairie Rivers Lincoln Highway Heritage Byway and Watersheds and Wildlife programs, local community partners, homeowners, other byways, and communities throughout Iowa as they move forward with education and on-the-ground practices geared towards improving the environment for pollinators in our state.

This project was made possible in part by Resource Enhancement and Protection Conservation Education Program (REAP-CEP) funding along with coaching support from the E Resources Group’s Dr. Jean Eells, a frequent Prairie Rivers of Iowa collaborator, and Rebecca Christoffel. The REAP-CEP funding also allowed Orngard to attend an online workshop by Doug McKenzie-Moher on Community-Based Social Marketing and Resiliency and Adaptation to Climate Change and the Iowa Conservation Education Coalition Winter Workshop.

Prairie Rivers of Iowa Participating in Iowa Gives Green – A Day of Giving

by Mike Kellner | Jul 28, 2022

This article was produced in conjunction with the Iowa Environmental Council

The natural beauty of Iowa is a gift to behold. We have a picturesque landscape like no other. We have incredible soils. We’ve had a stable climate. We’ve had diverse flora and fauna in the tallgrass prairie. The Iowa of today may look different than it did 200 years ago, but our state remains a beauteous marvel that deserves to be celebrated.

Too often in Iowa, we’ve put productivity ahead of beauty. We’ve put efficiency ahead of diversity. On August 3 nearly 30 environmental organizations across the state, including Prairie Rivers of Iowa and the Iowa Environmental Council will participate in Iowa Gives Green, a day of giving that shows Iowans’ commitment to our environmental promise.

Prairie Rivers of Iowa board member and founder Erv Klaas working with youth to teach water quality monitoring as part of our efforts to address water quality issues in the state.

This environmentally-focused day of giving empowers diverse groups to work together to support conservation, preservation, and recreation, and to engage Iowans on the same day with intentional action to support those efforts.

Gifts to Prairie Rivers Iowa and other organizations participating in Iowa Gives Green clean and protect Iowa’s waterways. During Iowa Gives Green and throughout the month of August a gift to Prairie Rivers will have twice the impact due to a matching gift by one of its founders and well-known and respected champion for the environment ISU Professor Emeritus of Animal Ecology Erv Klaas.

Ag leadership has been touting the same ‘solutions’ for Iowa water quality, without results to show for it. Our environmental and conservation groups have ideas to bring to the table. Your support will help these groups implement new ideas and practices to deliver real results.

protect and invest in habitat and landscapes. Iowa is one of the most changed landscapes on the planet. By supporting the efforts of groups that are preserving and rebuilding ecosystems through land management and conservancy helps, you can help to build rural economies and critical pollinator and wildlife habitat.
provide recreation and education opportunities. Iowa offers incredible recreation opportunities, but our state ranks one of the lowest in the nation for public land. Your support can help these organizations to expand and improve our recreational spaces.
take action on climate. Extreme weather events in Iowa are no longer the exception, they are the norm — hotter summers, intense but erratic rain events, or the December 2021 tornadoes. We need to address climate change together, now. With your support, organizations across Iowa can implement their plans and help you to get involved.
Grow clean sources of energy. Our state is a wind energy leader and solar power is poised to grow exponentially. These groups seek to improve the landscape for clean energy development, so our state can transition to true, 100% clean energy 24/7.
Address environmental injustices in Iowa. Right here at home, the majority burden of pollution from fossil fuels damages the health and well-being of lower-income and minority communities. Drinking water across the state is threatened by polluting chemicals, lead pipes, and aging infrastructure. Rural Iowans struggle to gain access to transportation improvements, recycling initiatives, and other environmental efforts. All Iowans stand to benefit when we address historical injustices.

Iowa Gives Green helps to create an environmental movement that makes access to Iowa’s natural beauty available to all Iowans regardless of their economic status or the communities where they live. Join us in celebrating and supporting Iowa’s environment on August 3 for Iowa Gives Green by coming together to show how much Iowans truly care about our environment at www.iowagivesgreen.org.

Prairie Rivers Staffer Shellie Orngard Named to Change for Climate Cohort

by Mike Kellner | Jan 28, 2022

The Iowa Conservation Education Coalition has created a select group of community environmental leaders to be part of a Change for Climate Cohort who will “receive training, professional mentoring and support, and funding to define and implement community projects that address real problems faced by Iowans due to climate change”.

Environmental leaders from across Iowa have recently been named to the cohort including Prairie Rivers of Iowa Lincoln Highway Heritage Byway Coordinator Shellie Orngard.

Dr. Jean Eells is seen here leading a visioning session for Prairie Rivers staff and board of directors back in 2019.

Thanks to Resource Enhancement and Protection Conservation Education Program (REAP-CEP) funding along with coaching support from the E Resources Group’s Dr. Jean Eells, a frequent Prairie Rivers of Iowa collaborator, the cohort will create partnership and spearhead project that will address climate change issues based on what is best for their local communities. Additional training sessions will Community-Based Social Marketing and Resiliency and Adaptation to Climate Change workshops. The cohort is slated to begin sharing their projects with their communities in early 2023.

In addition to Prairie Rivers’ Orngard, other new members to the cohort include Northeast Iowa Peace & Justice Center’s Sharlene Bohr, Erica Carns of the Blank Park Zoo, City of Dubuque Sustainability Office/Green Iowa Americorps’ Sam Harris, and Story County Conservation Naturalist Beth Waage.
