1. Introduction
The Mega-Catch Alpha Pro 900 is an advanced mosquito and flying insect trap designed for both outdoor and indoor use in small yards, patios, and gardens. This device utilizes patented technology to attract, trap, and eliminate various biting insects, including mosquitoes, sand flies, black flies, and biting midges, thereby helping to reduce their populations over time.
The trap employs a multi-faceted approach to insect attraction, combining visual, thermal, and chemical cues to maximize effectiveness. Its robust design ensures reliable performance in various environments.
2. Safety Information

4. Setup
4.1 Unpacking and Placement
Carefully remove all components from the packaging. The Mega-Catch Alpha Pro 900 is designed for optimal performance in small patios, gardens, and yards. For best results, place the trap:
- Away from areas where people gather, ideally 30-40 feet away.
- In a shaded, moist area, such as near shrubs or bushes, where mosquitoes tend to rest.
- On a stable, level surface.
- Near known mosquito breeding sites, if possible.
4.2 Installing the Octenol Lure
The Octenol lure enhances the trap's effectiveness by mimicking human breath. To install:
- Locate the Octenol dispenser at the base of the trap.
- Open the dispenser and insert the Octenol fragrance strip.
- Close the dispenser securely.
4.3 Connecting Power
Connect the power adapter to the trap and then plug it into a suitable outdoor-rated electrical outlet. Ensure the connection is secure.

5. Operating Instructions
5.1 Powering On/Off
Once plugged in, the trap will automatically power on and begin its operation cycle. There is no manual on/off switch. To turn off the trap, simply unplug it from the power source.
5.2 How the Trap Works
The Alpha Pro 900 employs a sophisticated system to attract and capture mosquitoes and other biting insects:
- Visual Cues: A digitally controlled LED display array pulses light in both visible and invisible spectrums at oscillating frequencies. These frequencies are known to attract a wide range of mosquito species, as well as sand flies, black flies, and biting midges.
- Thermal Cues: A powerful central core heat system generates heat pulses, mimicking the subtle changes in human body temperature. As insects approach, their thermal sensors detect this infrared signature, drawing them closer to the trap.
- Chemical Cues: The Octenol lure emits an air plume enriched with a known mosquito attractant, guiding insects towards the trap's base.
- Capture Mechanism: Once insects are drawn into the trap, they are swept through a fan and into the catch bag, where they are contained and eventually perish.
For optimal results, allow the trap to run continuously, especially during peak insect activity hours (dusk and dawn).

6. Maintenance
6.1 Emptying the Catch Bag
The catch bag should be emptied regularly, depending on the insect population in your area. It is recommended to check the bag weekly. To empty:
- Unplug the trap from the power source.
- Carefully remove the catch bag from the bottom of the unit.
- Dispose of the trapped insects.
- Reattach the catch bag securely to the trap.
6.2 Replacing the Octenol Lure
The Octenol lure typically lasts for approximately 30 days. Replace it monthly for continuous effectiveness. Follow the installation steps in Section 4.2.
6.3 Cleaning the Unit
Periodically wipe down the exterior of the trap with a damp cloth to remove dust and debris. Ensure the vents are clear of obstructions. Do not use harsh chemicals or abrasive cleaners.
7. Troubleshooting
If you encounter issues with your Mega-Catch Alpha Pro 900, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Trap not turning on | No power, faulty power adapter, damaged cord. | Check power outlet. Ensure power adapter is securely connected. Inspect power cord for damage. If issues persist, the power supply may need replacement. |
| Low catch rate | Incorrect placement, old Octenol lure, high wind, competing light sources. | Relocate the trap to a more suitable area (shaded, moist, away from human activity). Replace the Octenol lure if it's older than 30 days. Ensure the trap is not exposed to excessive wind or bright competing lights. |
| Fan not operating | Obstruction, fan motor failure. | Unplug the unit and check for any debris obstructing the fan. If the fan still does not operate after clearing obstructions, contact customer support for assistance. |
