A simple mosquito bite can mean serious illness or death. So we spray large areas with chemicals to wipe out mosquitoes. But this has a bad influence on the whole ecosystem and your health. Now there’s a new device (装置), which claims to keep you and your loved ones mosquitofree：
What are we talking about?
Mosquitron, a brand new type of bug (虫子) catcher, designed by two German engineers, is perfect for clearing your home of all annoying and dangerous flying pests!
How does it work?
◆It is easy to set up; plug it in — and away you go!
◆It lures (引诱) the flying pests near using a safe, completely harmless UV light.
◆A reverse fan sucks the insects through a oneway trapdoor.
◆Once trapped in the drying basket, they are dried to death by the fan within 2 minutes.
◆You can simply empty the dead bugs into the trash, without even touching them.
◆No need for batteries or any chemicals.
How much does it cost?
It’s now ＄179.99. It may seem expensive at first, but when you consider most devices need regular, expensive refills and don’t work for more than 10 minutes, this is a pretty good deal. In fact, competitor products using the same UV technology are priced at over ＄250! Now you can buy it from the supplier’s website with 50% off and with free shipping for a limited time by clicking here. Note: The device can only be returned or exchanged if it arrives damaged, and you must pay in advance.
