The best mosquito killer available, the best bang for the buck product, and a product that even keeps mosquito away for hours after it is used, that's Raid Yard Guard Mosquito Fogger. Nothing really comes close to this as a mosquito killer, and it uses a combination of pyrethrin based ingredients to get the job done. By spraying this fogger in and around the underside of hanging plants and leaves, it kills the mosquitoes where they roost. The ingredients stay in place for hours to prevent mosquitoes from returning. Yard Guard Fogger is fairly inexpensive and can be had either singly or in multiple packs. Although introducing toxins into the ecosystem may not be the most environmentally friendly way to kill mosquitoes, there can be no argument that this is the most effective and efficient method to kill those pests, bar none.
One of the best and most environmentally friendly ways is to kill mosquitoes at their source, and using Summit Chemical Mosquito Bits will do just that. This is a quick-acting mosquito formula made with a bacteria that kills mosquito larvae where they live. Sprinkle a handful of the Bits in any standing water where mosquito larvae are present, and within 24 hours, they will all be dead. This fast acting bacteria will bloom quickly, kill the larvae and die off. It works best if you know mosquito larvae are present, and for continuous control, you'll have to sprinkle weekly. Although highly effective and eco-friendly, it only kills mosquitoes where they are born and live as larvae, before they become adults.
When you want to use an environmentally friendly way to control mosquitoes for the long haul, Summit Chemical Mosquito Dunks are the way to do it. These are cousins to the Summit Mosquito Bits, but they are made to release mosquito killing bacteria for 30 days straight, and each dunk will treat over 100 square feet of standing surface water. This is an excellent way to keep ponds, brackish water and large pools of standing water from being infested with mosquito larvae. They are non-toxic to all other animals, are safe to use around kids and pets and they are even rated for use in organic gardens or waterways. Although they will not kill adult mosquitoes, they will eliminate mosquito larvae from the standing water where mosquitoes breed.
For a high-tech mosquito killer, check out the Flowtron PV-440 Galaxie Power-Vac Mosquito Control Unit. Just plug it in, turn it on, and it will attract mosquitoes over a one acre distance, vacuum them onto a collection tray and then dehydrate them until they have expired. It uses heat, light, scent, color, shape and motion to attract mosquitoes, and the scent pack can be replaced once it loses its effectiveness. It is completely non-toxic, safe to use around kids and pets, and will not harm the environment in any way. The bulb is easy to replace, it uses low voltage wiring for operation and the collection tray is easy to remove for cleaning. This is not an inexpensive unit, but if high-tech is your game, this is the mosquito killer for you.
If you want one of the most unique ways to rid your area of mosquitoes, try the Blue Rhino SkeeterVac SV5100 Mosquito Eliminator. Mosquitoes are attracted to CO2 gas that virtually every warm blooded animal secretes when they exhale a breath from their lungs. The SkeeterVac converts propane into CO2 gas that effectively attracts mosquitoes. Once they are in range, the powerful propane fueled vacuum sucks them up and deposits them onto sticky paper. They die quickly from dehydration, and in this way, mosquito infestation can be controlled. Since there is no electricity needed, this unit is portable and will work anywhere, as long as it is supplied with a propane tank. It covers up to one acre and uses easily replaceable and inexpensive sticky paper as the capture medium.
