I came to this forum yesterday because I have an infestation of mealy bugs. I noticed the Beautyberry post concerning mosquito repellent. I was curious since I have a couple of large bushes in our front yard. Yesterday, after rain and muggy temps, I took a few large leaves off one of the Beautyberrys and rubbed them on my arms, neck, and legs. I have to say I was skeptical that the mosquitoes would be covering me within 5 minutes. I had no bites, no landings. Then I thought it was possibly due to the neighbors' margaritas. So this evening, I decided to try it again. Right before dusk, I went out front with a glass of wine and picked a few leaves off the Beautyberry. No bites, no landings. I could see the mosquitoes circling, but not landing. I will continue my experiment tomorrow with gin and tonic.
Seriously, it seems to work! I would love to be able to stop spraying poison on myself just to get out in the garden in the morning. Mealybugs got a shot of soapy water and alcohol. They were not happy.
