I have had lots of people ask me if Mosquito plants actually do work, and my answer is yes. I have two growing just outside my door, and i have had a definite decrease in the number of mosquitos, from my average. I can now sit in my yard in the evening time, without nearly as many mosquitos. I do recommend buying more than just one or two. I mean, if you want the plants to perform to their maxium ability, then buy enough to do the job. I would gladly buy two more, if home depot still has them, which is where i purchased my first two. Also, if i happen across some seeds for thos citronella plants, i sure will list some on here for sale.
