Black Widow 800 Propane Bed Bug Heater – Add-On Package

Black Widow 800 Propane Heater Package with 2 High-Temperature Air Movers – Complete Heat Treatment for Bed Bugs

Designed for efficient and professional heat treatment for bed bugs, the Black Widow 800 Propane Heater Package delivers powerful performance and portability in a compact system. This package includes the Black Widow 800 direct-fired propane heater along with two AM3700 high-temperature axial air movers, offering everything you need to treat infested spaces quickly and effectively.

With an output of 85,000 BTUs—equivalent to 25.4 kW of electric heat—the Black Widow 800 is capable of treating 850 to 1,000 square feet when used with four fans (two are included in this package). The unit features a built-in 450 CFM fan, thermostatic controls, and remote temperature monitoring, allowing for precise and consistent heat delivery throughout the treatment zone. Most bed bug infestations can be eradicated in as little as 4 hours for small rooms and up to 8 hours for larger units.

Built for ease of transport and use in tight spaces like high-rises, apartments, and housing complexes, the heater weighs just 122 pounds and measures 31” x 22” x 27”. It runs on two standard 20-pound propane tanks (not included) and a single 120-volt grounded outlet, making it both versatile and easy to set up. The straight axle and sturdy wheels allow for smooth movement between job sites.

Certified to ANSI Z223.1 NFPA 54 standards for safety in the U.S. and Canada, this heater includes built-in sensors for flame, airflow, and temperature monitoring. With minimal training required, a single technician can safely operate the unit. Its directional airflow design pulls air from one side and pushes heated air out the other, creating even temperature distribution for effective bed bug eradication. Optional ducting can be attached to extend heated airflow deeper into the space.

Air Movers Included

The AM3700 air movers are designed for high-heat environments up to 158°F, making them ideal for heat treatment for bed bugs. Each unit delivers a powerful 3700 CFM and includes an hour meter, GFCI outlet, 2-speed motor, and a 25-foot power cord. These fans are daisy chainable, allowing up to 6 units on a 15-amp circuit or 9 units on a 20-amp circuit. For efficient storage, fans can be securely stacked up to 8 high—making them the most stable stackable high-temp air movers available.

Whether you’re a pest control professional or a property manager, this package is an excellent all-in-one solution for fast, reliable, and effective heat treatment for bed bugs.
