Active Aqua Bug Shield, 8"

Keep Pests and Spores Out of Your Airflow, Not Just Bugs

An open fan or duct opening doesn't just move air — it's an open door for insects looking for a way in and for the airborne fungal spores that hitch a ride right alongside them.

The Active Aqua 8" Bug Shield closes that door without closing off your airflow: its plastic mesh screen stretches over the opening, held snug by an elasticized rim and cinched tight with an adjustable drawstring, so air moves through while pests and spores stay outside.

Because the mesh is washable, it's built for the long haul — pull it off, rinse it out, and put it right back to work on intake or exhaust, wherever your system needs the protection.

Key Features & Benefits

• Sized for 8" fan and duct openings — stretches over the opening for a fit that matches your equipment without gaps at the edge.
• Plastic mesh screen — physically blocks insects of all kinds along with the airborne fungal spores that often travel with them.
• Elasticized opening — grips the rim of the fan or duct so the shield stays seated through normal operation.
• Adjustable drawstring — cinches down for a final, custom-tight seal once the shield is in place.
• Washable materials — rinse clean and reuse the shield instead of replacing it every time it picks up dust or debris.
• Suitable for intake or exhaust — works on either side of your airflow setup, wherever pests are most likely to get in.

Who Should Use This Bug Shield

This shield suits any grower running fans or ducting with a 8" opening who wants to block insects and fungal spores at the source — especially in rooms near doors, vents, or outdoor air intakes where contamination risk runs highest.

Matching the Shield to Your Fan or Duct Size

Active Aqua Bug Shields come in 6" and 8" sizes to match the most common fan and duct diameters. This 8" version is sized specifically for 8" openings — choosing the size that matches your equipment is what keeps the elasticized rim seated snugly and the drawstring able to finish the seal.
