"Whiteflies are more easily seen than thrips or mites because they fly around plants, especially when plants are shaken by gardeners or air movement. As their name implies, whiteflies are pure white, and are about the size of the
head of a pencil lead. Whiteflies drink plant juices and leave residue on plant surfaces that provides sustenance for harmful fungi."
If its what i think it is get that shit out now!
It points 75% toward white fly, 25% fungus gnat. Basically either are terrible recipes for disaster!
Whiteflies like the color yellow; one control for whiteflies is a commercially available yellow strip coated with sticky material that attracts whiteflies and then traps them.
Parasitic wasps released before whitefly infestation can keep whiteflies from taking over a grow situation. Sprays containing pyrethrum and organic gardening soap kill some whiteflies, especially when they are airborne. Whenever
using sprays, be sure to spray the underside of leaves thoroughly, as this is where many pests live.
Fungus gnats thrive in overfertilized, over-watered grow mediums, especially those where organic fertilizer high in nitrogen has been used. Gnats can be killed by disturbing soil, heating soil, by predatory wasps, and by applying insecticidal soap, neem, rotenone, and garlic oil to gnat infestations.
