No. You need much more coverage. Tiki torches are fun and citronella is not exorbitant - I think they give off a ton of smoke/odor and that's what works. I think the key is to create a good barrier, which means a lot of buckets or torches surrounding the area, and then you have protection no matter which way the wind is blowing. As someone else said, they all require supervision. I'm not sure any of it is all that great to breathe, frankly, but mosquitoes are a huge problem around here for EEE and West Nile virus. If you're trying to eliminate other types of bugs, you may need to change it up. Bug zappers work for some things, but not for mosquitoes which are not attracted to light. We use the torches and some stakes we bought at a discount store that stick into the ground - add the torches and get some height. We also use citronella buckets on the railing of our deck - different heights are important. I've used those smoky spirals and I don't think they stay lit too well, and they break easily. If you only use part of them and leave them in the rain, you can't use the rest though. A torch relights pretty easily, and a citronella bucket can either be covered with a lid or the rainwater dumped out. I do like the idea of something you can refill though, whether it's torches or those coil things, if you can make them work.
If it's only mosquitoes you're dealing with and if it's a small area, a good oscillating fan works great and it's non-toxic! Mosquitoes are weak fliers - that's why they don't bother you on a breezy day, but on a still day (especially moist and muggy) you really get assaulted.
I also don't think there's a big difference between the name brands and the discount stuff though, so I usually go by price.
