About

Carroll-Loye Research

Since 1989

Dr. Scott Carroll and Dr. Jenella Loye have pioneered scientific testing, product development and registration services for insect repellents, organic, natural and low toxicity pesticides, fertilizers and soil amendments.

Carroll-Loye Biological Research provides customized service, superior scientific practice in applied public health and agricultural entomology, and Good Laboratory Practice scientific services. We furnish regulatory and product development advice to facilitate registration under US EPA, PMRA, EU and other regulatory authorities.

We have the academic acumen and industrial experience to maximize your project's:

Relevance
Reliability
Information content
Cost effectiveness

We understand that the needs of our sponsors, whether large or small, are ill-served by a boilerplate approach. Everyone on our team of science and regulatory professionals welcomes discussion to best meet your objectives.

Global in scope, local everywhere

Carroll-Loye has broad expertise in public health, environmental entomology, product development and registration and academic biology. Carroll-Loye utilizes research sites and facilities nationally and throughout the world.

Working with the regulatory community

We work closely with regulatory bodies (EPA, PMRA, EU, FDA, DoD) to define best practices for meeting our sponsor’s needs and for sound science in general. Our in-house practices are integral to the recommendations of US EPA regulatory guidelines for insect repellent efficacy tests.

Is registration my responsibility?

Ensuring product effectiveness and safety, is the responsibility of everyone engaged in the development process.

As a case in point, the rapid spread of West Nile Virus, the unchecked epidemic of Lyme Disease and risks associated with global climate change have raised public awareness of insect repellents as well as expectations for performance and government oversight.

With this increased attention to insect repellents, and the growing concern about liability, businesses are searching for ways to:

reduce risk of poor performance
improve confidence in repellent safety and efficacy determination
fathom and comply with the EPA guidelines
differentiate themselves from the competition

Assuring reliable, effective and safe insect repellents depends on thorough and professional testing. Even if you use deregulated (‘25B’) active ingredients, efficacy should still be properly demonstrated. Carroll-Loye Biological Research can help you to meet your performance and safety goals.

Cass uses her background in field biology, ecology, and animal behavior to help design
and conduct field studies at CLBR. She received her Master's degree in 2018 from the Roehampton University in London on the influence of climate disasters on tropical primate social systems. Her experience working with animals ranging from wasps to monkeys in a wide diversity of environments helps us to perform accurate and effective field studies throughout the world.

Corwin is a broadly trained entomologist with expertise in ecology and taxonomy. He's high energy and always ready for sharp and muddy sides of field work (unless there's poison ivy/oak). At the same time Corwin is incredibly precise and efficient. He's a fourth-year PhD candidate at the University of California Davis studying bark beetle ecology and insect-nematode interactions. Corwin is also a fine artist.

Trevor Fowles designs and facilitates both lab and field studies. He's a keen observer of insect behavior, adding his entomological insights to develop biologically meaningful assays in our wind tunnel trials, host choice experiments, and field efficacy studies. Trevor has worked at Carroll-Loye since 2005, and is now also in the third year of a Ph.D. program in Entomology at University of California, Davis (across the street).

Ralph's professional focus on mosquito biology. He received his Master's degree in Entomology from UC Davis in 2017. He captains of the World Champion UC Davis Linnean Games Team, which under his leadership has dominated that premier academic insect trivia competition since 2015 . When he's not identifying mosquitoes in the field and rearing them in the lab, or memorizing cutting edge facts, Ralph is an in-demand public speaker and science educator.
