The 4F-M-W Series insect cages are designed for researchers working with very small insects, such as whiteflies, thrips, or early-stage mosquito larvae. These cages feature ultra-fine white nylon mesh (typically 150–300 µm), offering superior containment and ventilation, even in high-humidity environments.

The “4F” in the name indicates a fine mesh configuration, while the “W” refers to the white mesh color, which reflects light and helps regulate internal temperature—particularly useful in bright lab or greenhouse conditions. The all-mesh paneling ensures consistent airflow from every direction, reducing the risk of moisture buildup or hotspots inside the cage.

Each unit is equipped with a front-facing sleeve opening, allowing safe, controlled access for feeding, transferring insects, or collecting samples. The strong yet lightweight external frame makes these cages stable on lab benches or in insectaries, while remaining easy to handle and clean.

The 4F-M-W Series is trusted by agricultural research institutions, university labs, and entomology programs worldwide for its precision mesh control, reusability, and clarity during observation. Ideal for insect rearing, host plant studies, resistance trials, and bioassay setups involving tiny insect species.
