Advertisement I was looking around at foggers awhile back and almost got one until I found somewhere how to make one since I already had a small humidifier. I'm not in any way great with building things but if anyone has a humidifier already all you really need is some PVC pipe and elbow joints. You can either use some kind of glue to glue in the pipe or like me I just used Duct Tape (its ok to laugh) because I plan on reusing the humidifier. The most difficult part, which is not difficult if you have tools is cutting the pipe to size. A lot of home repair stores will do that for you if you bring them your measurements. I've even cut them with my large garden shears before--whatever works. Anyways I had everything I needed already minus the pipe which cost me about $7 for everything. If anyone is looking for a simple and very effective fogger, turn your old humidifier into one. Its probably easiest if you have one with the hole on top. I've had mine running for over a month and it works flawlessly.
