The EazyZap chain door fly screen is a practical passive pest control solution designed to cover doorways up to 900mm wide. It works by suspending overlapping aluminium chains across the door opening, creating a physical barrier that flying insects are reluctant to pass through, while remaining easy for kitchen staff to walk through without breaking stride. Unlike solid door closers or plastic strip curtains, the chain construction allows air to circulate freely — a useful property in kitchens where keeping air moving through back-of-house areas matters during busy service. In day-to-day commercial kitchen use, this type of screen earns its place at external doors and delivery entrances that must remain open during warmer months. It requires no power, no maintenance schedule, and no adjustment — once fitted, it works passively without any staff input. The aluminium construction keeps the weight manageable while holding up well in high-traffic doorways where a screen is pushed through repeatedly throughout the shift. No electricity required — fully passive pest deterrent Allows airflow into hot kitchens without compromising pest control Comfortable to walk through at pace, minimising workflow disruption Aluminium chains resist moisture and grease-laden air Simple installation with no specialist tools or maintenance needed Installation is straightforward — the screen mounts to the door frame and the chains hang to cover the opening. It suits single doorways up to 900mm wide; wider openings such as double doors or loading bay entrances would need a different approach. No electrical connection, water supply, or ventilation provision is required. This screen is well suited to catering kitchens, food preparation areas, cafés, and takeaways where an external door is left open during service. It is a cost-effective first line of defence rather than a standalone pest management programme, and works best as part of a broader hygiene and pest control approach.
