Works great for catching nasty flying bugs and mosquitoes and fruit flies. I will buy again.

We ordered the DynaTrap 21050 9-Watt UV Light Bulb Replacement for Indoor DynaTrap Insect and Fly Trap Models DT300 8 months ago. We installed it as soon as we got it and left it on for 8 months. Today I am going to order the same product since it finally stopped working. For 8 months it did a great job killing flying insects in our kitchen. It attracted and caught insects as big as flies and down to the size of fruit flies. It works well. I considered buying the much cheaper replacement bulbs that come 2-4 in a pack, but then I read the reviews. Most of them reported that the other bulbs were defective when they arrived or quit working after a short time. I am going to reorder what worked so well for me, the DynaTrap 21050 9-Watt UV Light Bulb Replacement.

Update: We ordered the replacement bulb in January. It worked until June. We keep it on all the time, 24 hours a day. I was hoping it would last a bit longer, but plan to reorder with subscribe and save for 6 months.

I love how cheap these are; they're perfect for my bug zapper. Who knew two tiny bulbs could save my backyard from those awful mosquitoes! Someone nearby has a huge puddle, making my yard unbearable. You get bitten twenty times in under four minutes—it's terrible. Spraying didn't work, and nothing else did either. Once I got a bug zapper that uses these bulbs, I stopped hating my own property. They last forever and totally do the job. I keep extras on hand so I never have to go without our bug machine. Buying these bulbs locally was crazy expensive. So glad they're affordable on dynatrapoutlet.com.
