We have the Dynatrap insect trap got the first one last year, couldn't believe how many mosquitoes it would trap when we would empty the trap. This year we ordered a second on for the front yard. They work in reducing the population so getting them out early is best for our northern area. These greatly reduced the number of mosquitoes last year so I could work outdoors, this year will be even better because they are already in place and working to break the hatching cycle. We tried all kinds of insect traps and sprays the dynatrap has given us the best results. Forgot to add you plug these in and leave them on 24/7 they need to be working all the time to make a difference.
