Mosquito Traps
Our battery-powered mosquito traps utilize incandescent, UV, or LED lighting with CO2 release systems for optimal collection efficiency. Designed for both day and nighttime operations, these traps target specific species like Aedes aegypti and Culex mosquitoes. Advanced models feature programmable timers and photocell controls for automated field deployment in disease surveillance programs.
Aspirators
We manufacture manual and battery-powered aspirators for laboratory and field use, including CDC-designed backpack models and HEPA-filtered mouth aspirators. Our 6-volt Prokopack Aspirator enables precise specimen handling with variable-speed suction, ideal for human landing rate studies and cage transfers while maintaining biosafety standards during sample collection.
Droplet Samplers
Our impinger-based droplet samplers calibrate insecticide spray equipment and measure aerosol drift patterns. The Florida Latham Bonds model captures precise droplet size distributions for modern high-pressure systems, while the compact version suits conventional spray applications, supporting EPA compliance testing and equipment optimization studies.
Flight Traps
Sun-resistant polyester flight traps like the Standard 6-Meter Malaise Trap capture diverse insect species for ecological studies. The Migration Trap tracks directional movement patterns, while specialized models like the Adult Mayfly Updraft Trap target specific research needs with non-destructive specimen collection methods for taxonomic analysis.
Battery Systems
We provide lead-acid and lithium-ion battery packs with compatible chargers for extended field operations. Our solar-powered charging systems support remote deployments, while the DC-DC buck/boost converter enables 6-30V battery compatibility. Technical specifications include runtime optimization guides for different trap configurations and environmental conditions.
Questions
What mosquito species do your traps target?
Our traps specifically target Aedes aegypti, Aedes albopictus, and Culex species including Culex quinquefasciatus, with specialized models for gravid females and daytime-active populations.
Can your equipment be used for disease surveillance?
Yes, our CDC-developed traps are widely used for arbovirus monitoring programs targeting Zika, West Nile, and Dengue virus vectors with proven specimen integrity preservation.
Do you offer customization options?
We provide custom trap modifications and collaborate on new product development based on field requirements, with recent examples including military-spec stealth traps and storm sewer monitoring systems.
What power options are available?
Our equipment supports 6-24V battery operation with solar charging capabilities, including lithium-ion alternatives offering 3x runtime compared to standard gel cells.
How do your aspirators ensure biosafety?
Our HEPA-filtered models prevent inhalation of insect particles, while waterproof cases and autoclavable components maintain laboratory safety standards during specimen handling.
