The John W. Hock Company specializes in tools for collecting mosquitoes and other insects. Our tools are used for scientific research, risk assessment, and vector-borne disease control programs.
 
Mosquito and Sandfly Traps

Day or nighttime collection of mosquitoes and sandflies including specific traps for Aedes aegypti and Aedes albopictus or gravid Culex mosquitoes. Battery-powered traps feature incandescent or blacklight (UV), downdraft or updraft fans, CO2 release and photocell control.
 
Insect Flight Traps

Proven insect flight collection traps made from sun-resistant polyester with double or triple sewn seams. Models include The Standard 6-Meter Malaise Trap, The Migration Trap, and The Light-Weight Townes Trap.
 
Programmable Collection & Droplet Samplers

Segregate the catch into distinct time periods with programmable collection controlled by an advanced timer. Use our Aerosol Droplet Samplers to accurately calibrate spraying equipment.
 
Aspirators

Collect mosquitoes and other larger species with our agricultural (gas-powered) or CDC-designed (battery-powered) backpack aspirators. For manually aspirating mosquitoes and sandflies in the lab and field, use our mouth aspirator with optional HEPA filter.

 
Batteries, Chargers and Accessories

Keep your trap running at top performance with the right battery and charger along with our extensive battery tutorial. Customize a trap for your application with our many accessories and options.

 
 
 
New Frommer
Updraft Gravid Trap
  
 
The new Frommer Updraft Gravid Trap Model 1719 operates in a fashion similar to the CDC Gravid Trap but has a collection chamber below the fan so the adults are not exposed to the aspiration fan; the result is pristine specimens that are easy to identify. <more>

Photocell-Controlled CO2 Release Option
  
 
A small precision pneumatic valve is controlled by the trap's internal photoswitch that turns on and off the release of CO2 with light level. <more>
