i noticed yesterday that there are these little bugs that fly around when i mess with my plants. they are real little black bugs with a lighter abdomen, (making me assume that they are gnats). there only seems to be 6-12 of them that i can notice. ive seen them more on the dirt surface than on plant, but you can tell that something has been eating on them, there are black, brown, & white spots, & even chew trails on some leaves like a catapillar would do. also there are tiny black ants that also showed up yesterday, killed what i saw, no more today. so i have this stuff called
BANG! (got it for free), 
its a 100% organic insect inhibitor and is especially effective against spider mites and also inhibits most other plant damaging insects. Use it up to three days before harvest, indoors or outdoors, on fruits, veggies, flowers, and trees. Great for hydroponics. This non-toxic combination of fruit and vegetable extracts is brewed in small batches to ensure quality. Will not harm birds, pets, or people once applied to your plants. will this kill whatever pest i got. i will try to take pics of them, and the damage. also i heard ladybugs are good pest control, where can you get them, & will they harm the plants once the bugs are gone. thanks
