I bought me the one acre Dynatrap DT2000XL about a week ago after researching it for some time now. I installed it out by my Garden to help keep the moth and mosquito population down in the back yard so that when I hold a fish fry outside we wouldn’t be eaten alive and to help protect my garden.
To help beef up the effectiveness of it I also used a Octenol Lure and after one week of continuous running it has performed as advertised. The trap is about half full and there is a mix of insects in the trap. With all the rain we have gotten the past week I think might have hampered some of its ability to catch more mosquito’s than it has but a majority of the insects that are in the trap are mosquito’s and moth’s.

Here are some of the pros an cons that I have found from researching it online.
Dynatrap Pros
Its initial cost is cheaper than propane traps.
It doesn’t require the hassle and expense of replacing propane tanks.
It catches other bugs besides mosquitoes, though that’s not always good if they’re beneficial ones.
You can use it indoors or outdoors.
The only sound is the quiet humming of the fan and there’s no odor.
It’s safe for pets, children and the environment, since it uses no insecticides.
Dynatrap Cons
The big one: it doesn’t necessarily kill mosquitoes specifically, so you may get more moths or other things instead.
You’ll need to mount it about 5 to 6 feet off the ground. One model, the DT1200, comes with its own hanger, but otherwise, it needs a tree branch, post, wall, fence, etc. to hang or sit on.
If you use it outdoors, it may need some rain shelter to prevent water from getting into the collecting area.
It needs an outlet 7-10 feet away or an extension cord.
It’s tricky to empty without letting some bugs escape.
The claim that it emits an effective amount of CO2 has been questioned.
Like all traps, it needs placed in a good location, shady and sheltered, where mosquitoes can find it, but not where you’ll be bothered by them.
