I was eager to try the DynaTrap DT1130-GRSR Mosquito/bug trap as we have a lot of rain in the spring and get a lot of mosquitos as a result. We have the standard bug zappers that can be loud, so I was excited to see how quiet this unit is. After running it a while, it did trap a collection of bugs. I can't say that this totally eliminates all the mosquitos in a given area though. We use it on the back patio, and while it does attract and trap quite a bit, there's still a lot of those bloodsuckers flying around to get us. But, using it in conjunction with our existing bug zappers and some mosquito dunks, the number of mosquitos 'bugging' us is greatly diminished. I may look at getting another one for our front porch.

I run this trap on my off grid cabin. I put new bulbs in every spring. This year mosquitos came early so I placed the bulbs early. They both worked, so I drove home. A couple weeks later I was back and one of them is bad and I can't get it to work on either side.

I recently purchased replacement bulbs for my Dynatrap, and the old bulbs have been working well for a whole season of continuous use. Although the bulbs are white instead of blue, DynaTrap claims that both colors emit UV light and are equally effective at attracting mosquitoes. Interestingly, after about 20 minutes of use, both white bulbs (6-Watt) started casting a blue tint, which I managed to capture in a photo. However, one minor issue --replacing the bulbs can be challenging when there are bugs around. It requires twisting the bulb and unscrewing the protective light cover, which can be tedious for people with larger hands. But once you get the hang of it, it can be done quickly.
