Have you had any experience with electric ultra sonic bug repellers? If so do they work well for bug infestations?
I’ve never heard good things about so called "sonic" bug repellers of any kind. Over the last two years however, I have become a very big fan of the DynaTrap Insect Trap. Our home is located adjacent to wetlands where mosquitoes are very prevalent. Over the last two years I have used DynaTrap, we hardly had a single bite!
DynaTrap works differently than other mosquito products. It emits a UV light that draws bugs close, and then CO2 (irresistible to mosquitoes) is released by the photo-catalytic reaction of Titanium Dioxide treated surfaces and UV-Light. Finally, a fan captures the insects and draws them into a screened in basket where they literally pile up. If you get one, here’s a tip — plug it in and leave it on 24/7. Over time, it actually decreases the mosquito population, making it even more effective.
