Mega-Catch Ultra Mosquito Trap

The Mega-Catch Ultra is one of four traps produced by Mega-Catch.

Female mosquitoes find their prey by using a combination of sensory clues such as heat, sweat, and carbon dioxide, to name just a few. This trap mimics these human or animal characteristics to entice mosquitoes into the trap where they die.

The Ultra trap is renowned for being more reliable than some of the propane mosquito traps. Also, tests have shown that it catches more mosquitoes than other traps. This is probably because these traps have multiple combinations that simulate the sensory clues emitted by humans or other animals.

Many settings

The trap has many options so it may take a while before you find the optimal settings.

It has a heating element to imitate the body temperature of warm-blooded animals, LED lights are set up to imitate movement, the optional CO2 gas system imitates human or animal respiration, an Octenol attractant can be included, and adding soda or syrups to the water in the catch buckets, tricks the mosquitoes into thinking they have found a source of energy.

Altogether this trap provides a wide range of attractants, and most of these have several different settings, which means you can experiment until you find the settings that give you the best results.

To get the most out of your trap, it will probably take some trial and error to find the right combination of mosquito attractants and the best position in your garden.


It’s recommended to place the trap between the source of mosquitoes and the area where people gather. Like with any other bug zapper, it should not be placed too near any area you may use. Otherwise, the mosquitoes will just be attracted to you, and you may make matters worse instead of better.

An ideal position is a sheltered area, in the shade upwind, from the mosquito source and about 30 – 40 feet from where people gather. The trap should be suspended about 2 or 3 feet off the ground. To enable this, the trap comes with a stand.


It may take time to find the right combinations of CO2, lures, lights, heat, and placement, but once set up, this mosquito trap will help you reduce the number of mosquitoes in your yard. According to tests comparing other well-known mosquito traps, the ULTRA was the most effective in capturing more mosquitoes than other models.

  • The majority of customers seem satisfied with the mosquito catching prowess of this trap. In general, they seem to have better results than with other traps they were previously using.
  • It attracts mosquitos from over 150 feet away and covers an area of about 1.5 acres. Also, it attracts other biting insects such as black flies and biting midges (no see-ums)
  • The wet catch bucket can be used with a mixture of water and a sugar-based drink. This creates a humid airflow that is like human breath. You can also place any other of your homemade lures at the base of the trap. Some have reported success with smelly socks or certain cheeses.
  • One of the things I like most about this trap is that it doesn’t seem to kill many other insects like moths, butterflies, or bees. If you do find you are catching moths, you can turn off the UV tube.
  • Using no chemicals makes this an environment-friendly mosquito trap with no danger to pets, children, or other wildlife.
  • The automatic timer allows you to program the trap to work only when you need it or when the mosquitoes are active. This is usually early morning or in the evening. Possibly through the day if you have mosquitoes that bite during the day.
  • The support seems to be very good, and I have read reviews from customers who have had outstanding service even with old units. Many people seem to have had their units for 7 or 8 years, which is encouraging.
  • DIY maintenance -these mosquito catchers are designed to be serviced by their owners. On their website, they have videos and worksheets that can be downloaded.
  • You can choose whether to use CO2 and an Octenol lure or not. These may increase the capture rate but also your running costs. However, the carbon dioxide cylinder on the recommended setting should last about 4 months. This is a lot longer than the cylinder used on a propane trap.


  • The high initial price is the biggest con. Some customers seem quite happy while others find it overpriced.
  • Some buyers report that the timer unit seems to die quite often. This will be replaced for free if still under warranty.
  • The unit seems to get much better results if used with CO2. This means you will have to add a CO2 cylinder to your expenses. The quantity you use will depend on how many hours you have your Mega Trap running.
  • You will have to empty your trap often and clean the fan, but this is normal for all traps.


Although the price is high, most people seem to be happy with this Mega-Catch mosquito trap. The positive reviews outnumber the negative reviews by more than 2 to 1.

Even some of the negative reviews are happy with the number of mosquitoes they are capturing. Some seem to be disappointed that they still had mosquitoes in their yard!

One important point when you are paying so much for a mosquito trap is the customer service. This seems to be excellent. I read of one customer who contacted customer service after having a problem with their unit when it was just out of warranty. The support replaced the faulty part free of charge and even threw in a few extras. Having customer service like this is a great advantage!

The DIY maitenance with video and work sheets, is also something that seems to be a good idea.

It does seem necessary to use CO2 for the best results, but some users have good results using the trap, with their own concoction of water and a sugar-based drink in the wet catch bucket. When you receive your ULTRA trap, it’s a good idea to try a few different mixtures in the catch bucket to see what it catches. Later you can add the CO2 to compare what works the best and to see if it’s worth the extra expense of using the CO2.

You may need to experiment with different settings and placements before you see substantial catches. So be patient!

If you can afford the price, this seems to be a great mosquito trap. This Mega-Catch trap will not eliminate 100% of mosquitoes but will drastically reduce numbers allowing you to profit from your garden again.

Mosquito Control

A mosquito trap should only be considered as one weapon in your war against the skeeters. For your safety, you should still consider using other repellents or putting an EPA-registered insect repellent on any bare skin, and a long-sleeved shirt and trousers could still be useful. And most importantly, continue to remove any standing water (that can be breeding grounds) from your property.
