Mosquito killer
in [Design]

From: George Jefferson on 8 Apr 2010 05:18 Is there a chemical deadly to mosquitos that is lighter than air? I was thinking about making an device that could kill them. I guess it's probably no better than a bug zapper. The idea is that since they, supposedly, are attracted to CO2, to make a bucket with an inverted code with a hole at the bottom. The mosquitos find there way to the hole which is releasing CO2 then go instead. The gas is trapped at the top of the inverted cone which should kill them. |\ /| | \ / | | | ------- They probably already make this sorta thing but it seems like it would be something rather easy and very cheap and one could place several of them throughout the property which is more efficient than just one or two zappers. The gas would allow one to increase the opening hole size which might be more effective. Seems they already have many of these types of devices. Most don't use the gas. Probably not necessary. Do these devices work well? I can get a small cylinder of CO2 and rig something up quite easily if it's worth doing.

They are also attracted to the right IR frequency so you would need a way to keep the temperature at about 37-38 degrees C. Perhaps a tea light candle under a ventilated ceramic cover inside a can or bottle of the design you describe.

HF (too reactive), NH3 (too soluble) or HCN but only by a tiny amount. It is also deadly to most other forms of life. Expect a visit from homeland insecurity and free accommodation in some hell hole if you try to buy it. > > I was thinking about making an device that could kill them.

Electric traps make a satisfying frying noise when the creature meets its end. There are plenty of reviews of existing designs online. Regards, Martin Brown

It's not poisonous, but it displaces air, so that anything needing oxygen would suffocate. It does, of course, require the concentration to be kept really high inside your trap. -- RoRo |
