Imidacloprid is the active ingredient. Use as directed.
I should add that the key to getting fast results with succulents such as aloes is letting them get thirsty. This will rush the treatment to the affected areas. The 3 Bainsii I treated had 'orangish' leaves before I would give them a drink. A well watered aloe, with thick, green fleshy leaves will take longer to absorb the Merit. All theory of coarse, but hopefully you've learned not to doubt me by now...
BTW, it does come in granules as well. I prefer the water soluble powder.
