How can I get rid of mosquitoes?
There are conflicting reports about the health risks involved with burning citronella indoors and I do not encourage it. If you plan to use a candle indoors as a device I strongly suggest using an inclosed candle box. Fire is a guest in your house and sometimes gets hungry. Also, citronella repels mosquitoes, it doesn't kill them. I suppose this would make them go into the other room at least. Used outdoors, tiki-torches and candles should be relatively safe, health-wise.



Does a Wantrn really work? Reading "also there is so high Voltage, So it’s very high safe and Quiet." in the product description is not encouraging. But the technology seems sound. CO2 and UV attracts, fan sucks them in and keeps them there. Perhaps it does work so long as there's power.



Even if it is one of models that work, your mileage may very:


  Government studies find the Mosquito Magnet line very effective, user postings paint a more nuanced picture. For example, the nearly 30 users posting to Amazon.com give the Patriot an average score of 3 out of 5 stars, with some calling it effective and others complaining that mosquitoes are still plentiful. Some who report success say it may be necessary to test the trap in multiple locations to find an optimum spot. Many also note that the trap is expensive to maintain, as the propane, optional chemical attractants, catch net and cleaning cartridge must be replaced periodically.


An excerpt from a highly suggested read and its links to other studies, before you drop that kind of money. I wouldn't feel safe with a propane model indoors. CO2 is not harmless but I wouldn't be concerned at all with the levels from one without a tank, even used indoors. However, being the guardian of a child a little research on the exact output is warranted. A good question might be how many CFM's a given space needs to keep the air fresh with a continual input of X number PPM of CO2.
