Conical Indoor Mosquito Trap with Light and Liquid Lure

The problem

Indoor pest control devices often use high-wattage ultraviolet tubes or exposed electrified grids. These approaches consume substantial electricity, generate audible snapping noises when insects are caught, and introduce exposed electrical components into living spaces. Furthermore, many traps are designed for large open areas rather than the specific flight patterns and resting behaviors of mosquitoes inside homes or offices. When a trap relies solely on light, mosquitoes may circle the device without being captured, reducing the overall success rate in enclosed rooms.

The solution

This device addresses these points through a combination of physical shape, targeted lighting, and liquid bait.

1. A conical box body (1) narrows downward, creating a confined space where mosquitoes that enter through the top have difficulty finding the exit.
2. A mosquito inlet (2) at the top opening is fitted with a detachable separation net (mesh diameter about 4-10 mm) to keep larger objects out while allowing target insects to pass.
3. Directly below the inlet, a light-emitting device (3) provides attraction. The patent describes using an LED white light or a light-emitting element radiating purple light at a wavelength of about 365 nm.
4. Beneath the light sits a trapping device (4), which consists of a containing box (401) with an open upper end. This box is filled with a trapping liquid, such as a viscous sweet liquid, to attract and catch mosquitoes.
5. A bottom cover (5) seals the lower section and connects to a base (6) that routes power from a supply to the light-emitting device.
6. On the exterior, a curling device (7) stores a black attractant (8) made of paper, plastic, or cloth, which unrolls to cover the outer surface of the box body.
7. Internally, an electrical installation uses conductive rods connected to a connecting shaft (9) that press against a resistance strip. Changing the contact point alters the circuit resistance, adjusting the brightness of the light.

Who it is for

• Home appliance brands looking to add a low-power, grid-free insect trap to their indoor product lines.
• Amazon private-label sellers sourcing quiet, visually distinct pest control devices for home and bedroom categories.
• Hospitality wholesalers supplying hotels or guest houses where a silent, spray-free trap with a sweet-bait option suits guest rooms.
• Hardware distributors expanding their seasonal pest management catalogs with electrically simple traps.

How it works

The main parts

Operating steps

1. Preparation - Detach the box body from the bottom cover, remove the containing box, pour the trapping liquid (e.g., a viscous sweet liquid) into it, and reassemble. Unroll the black attractant from the curling device to cover the exterior.
2. Power on - Connect the base to the power supply. The light-emitting device illuminates through the through hole in its connecting seat.
3. Attraction - The light and the black exterior draw mosquitoes toward the top inlet. They pass through the separation net into the conical interior.
4. Capture - Drawn by the light and the scent of the trapping liquid, mosquitoes move downward into the containing box where they are caught by the viscous liquid.
5. Brightness adjustment - If needed, rotating the box body on its bottom cover shifts the conductive rods along the resistance strip, changing the light intensity to suit the room size or power limits.

Applications

Bedrooms and sleeping areas

Users need quiet pest control overnight without the snapping sounds of electrified grids. The adjustable light keeps illumination low enough for sleep while the liquid lure operates silently.

Hotel and guest rooms

Hospitality buyers want a trap that runs silently and has no exposed electrified grid near guests. The enclosed conical shape and lack of exposed high-voltage parts make it suitable for bedside tables or room corners.

Offices and workspaces

Employees are distracted by flying insects near desks. A compact trap placed on a shelf draws mosquitoes away from workers using the light and dark exterior contrast without disrupting the environment.

Restaurants and cafes

Food service operators often prefer not to spray near dining tables. With a sweet, non-pesticide bait, the trap relies on light and the liquid lure, keeping the capture mechanism contained within the box body away from food preparation zones.

Where it is less suitable

• Large outdoor patios or gardens - the device is described for indoor and closed environments; open-air spaces require higher-output or wind-assisted traps.
• Areas requiring immediate knockdown - liquid lures take time to catch insects compared to high-voltage grids or fan-suction traps.
• Environments where liquid spills are unacceptable - the containing box holds a liquid, making it less ideal for locations subject to heavy vibration or frequent tipping.
