Efficacy testing
Carroll-Loye Biological Research provides efficacy testing for personal, backyard, and commercial insect control products, including on-skin repellents, spatial repellents, barrier sprays, knockdown formulations, larvicides, and device-based interventions. Our laboratory, semi-field, field and human subject assays support product development and regulatory submissions across a wide range of biting arthropods, household and commercial pests.
Human Subject Insect Repellent Studies
Real-world testing that evaluates how products perform when applied to skin or used near people under laboratory, semi-field, and field conditions. Supports bite-prevention, landing reduction, and duration of protection claims. Applicable to mosquitoes, ticks, and biting flies.
Spatial Repellency
Testing that shows how insects respond before they ever make contact. Supports spatial repellency, area-of-protection, and repellency-duration claims. Applicable to mosquitoes and other flying insects.
Contact &
Knockdown Efficacy
Assesses how quickly products incapacitate or kill insects following direct exposure. Supports contact efficacy, knockdown speed, and mortality claims. Applicable to mosquitoes and other flying and crawling insects.
Barrier Spray &
Residual Surface Efficacy
Evaluates residual performance of products applied to treated surfaces over time. Supports barrier protection and residual efficacy claims. Applicable to mosquitoes, spiders, lice, and other structural or household pests.
Aquatic &
Larval Control
Tests products designed to control immature insects in water. Supports larvicidal efficacy, dose–response, and residual-activity claims. Applicable to mosquito larvae and other aquatic immature stages.
Insect Trap &
Device R&D
From concept to performance proof. These studies generate data on attraction, capture efficiency, and comparative device performance to guide design decisions. Testing covers mosquitoes and other target flying insects and supports trap development, optimization, and iterative prototyping.
