Electric Garden Insect Trap with Attractant Dispenser and Auto-Cleaning Cylinder

The problem

Outdoor pest management in parks, gardens, and orchards relies heavily on traps that catch insects but require constant manual attention. Maintenance crews must climb ladders or reach into devices to remove dead insects, which interrupts operations and exposes workers to decomposing material. Many traps also depend on a single lure method, such as light alone or a static chemical pad, limiting their effectiveness across different times of day or target species. Without a way to clear the collection chamber mechanically, traps fill up quickly, blocking entry points and reducing capture rates.

The solution

This device addresses these issues by combining an attractant delivery system with a motorized clearing mechanism inside a sealed housing.

1. Attractant delivery: A pesticide storage tank holds an insect attractant. A gas guide pipe routes the vapor to an annular microporous ceramic membrane seated in an annular groove inside an isolation sleeve. The scent exits uniformly through insect inlet holes arranged around the circumferential surface of an annular seat at the top of the housing.
2. Guided entry: A conical guide sleeve extends downward from the inner diameter of the annular seat, narrowing into a guide pipe that reaches into the insect storage cylinder. Insects drawn by the scent or optional trap lamps pass through the inlet holes and slide down the conical path into the cylinder.
3. Automated clearing: An electric lifting mechanism, consisting of a motor and a screw rod connected by a coupler, drives the insect storage cylinder up and down. The cylinder slides on the outer side of the isolation sleeve. Damping strips fixed on the isolation sleeve provide friction greater than the threaded connection between the screw rod and the cylinder’s central hole, ensuring controlled movement.
4. Discharge: The side surface of the insect storage cylinder has multiple insect discharging notches. When the motor lowers the cylinder to its limit position—stopped by a limiting block on the screw rod hitting a plug in the central hole—the notches align with a connecting cylinder at the center of the housing’s bottom surface. The bottom surface of the storage cylinder is a conical surface with a high middle part and a low edge, directing dead insects out through the notches and the open bottom of the connecting cylinder.

Who it is for

• Municipal park departments maintaining public green spaces who need to reduce the labor hours spent manually emptying static traps across large areas.
• Commercial orchard and nursery operators managing crop pests who benefit from a device that can run continuously without daily intervention.
• Landscape maintenance contractors offering pest control services to residential or commercial properties who require durable, mountable equipment.
• Pest control product brands looking to add an automated, dual-lure outdoor trap to their catalog for B2B distribution.

How it works

The main parts

Operating steps

1. Deployment: The unit is hung from a tree trunk via the lifting ring (8) or placed on the ground using the support rods (14) and pins (140). Power is supplied via the power cord (10).
2. Luring: The attractant in the pesticide storage tank (4) volatilizes. Vapor travels through the gas guide pipe (5) to the annular groove (110) of the microporous ceramic membrane (11), diffusing out through the insect inlet holes (200). If equipped, trap lamps (12) illuminate through the light-transmitting plates (13).
3. Trapping: Insects enter the holes (200), slide down the conical guide sleeve (201) and guide pipe (202), and fall into the insect storage cylinder (3).
4. Clearing: The motor (60) turns the screw rod (61). Because the friction between the isolation sleeve (203) and the storage cylinder (3) exceeds the thread friction, the cylinder moves downward. The limiting block (610) meets the plug (303) at the lowest point. The discharge notches (300) align with the connecting cylinder (100), and the conical bottom pushes dead insects out.
5. Reset: The motor reverses, raising the storage cylinder back into the housing (1) to resume collection.

Applications

Public parks and botanical gardens

Park maintenance teams manage large areas where manual trap checking consumes significant time. This device hangs from trees or stands on paths, automating the clearing process so staff only need to refill the attractant tank periodically rather than emptying dead insects daily.

Commercial fruit orchards

Orchard operators target specific pests during growing seasons. By selecting an appropriate attractant for the target species, the trap operates continuously among the rows. The automated discharge prevents the collection chamber from overflowing during peak insect activity periods.

Plant nurseries and greenhouses

Nurseries require strict pest control to protect young stock. The combination of scent lures and optional trap lamps provides coverage both day and night. The sealed housing and guided entry prevent trapped insects from escaping back into the growing area.

Golf courses and resorts

Groundskeepers need pest control that does not disrupt visitors. The device can be mounted discreetly on trees along fairways or perimeter fences. The electric clearing cycle runs quietly, avoiding the visual disruption of maintenance crews constantly servicing standard traps.

Where it is less suitable

• Indoor home use: The device is designed for garden and outdoor environments, relying on attractants and support rods or hanging rings suited for exterior settings.
• Areas without power access: The electric lifting mechanism requires a power connection via the power cord, making it unsuitable for deep wilderness locations without electrical infrastructure.
