The Bayer appears to have put the serious hurt on these little fuckers. Day 1 after treatment showed no signs of life, just carcases. Day 2, we saw a couple of flyers which could have been fungus gnats, but it drove home the point that 3 - 4 treatments will be needed to assure complete anihilation. Day 3, there were no signs of life and we did a nutrient feeding. Second round of Bayer planned for sometime next week. After comparing Bayer Citrus & Vegetable vs. Tree and Shrub, the only difference appears to be the amount of imidicloprid. C&V is 0.23% and T&S is about 2.75%. Instead of the 50ml per gallon we did with the C&V, we are simply going to dilute the T&S at 7ml per gallon to achieve the approximately same amount. The T&S was $4 more at Home Depot, but a single bottle of T&S will allow us to do the remaining 3 treatments and we will likely have some left over.
