Oops I didn’t read the responses before mine. They can be a nuisance once they take hold. Wiping them out requires CONSISTENCY with whatever spray applications you employ. Every 3 to 5 days generally (with the less toxic products). I personally go with avid or the like one or two applications will destroy them. At this point continuous applications of deterrents like nuke em or IPM by Athena (pricey) applied 3 then gradually to 5 day intervals should prevent them getting a new foot hold. It’s nice to use strictly safe or organic pesticides but they are most effective as maintenance sprays 3 or 5 days apart when the atmosphere is already PEST FREE. They have much more difficulty gaining that foothold ( assuming healthy cultural practices are already in place as the norm). If pests do indeed infiltrate then at the FIRST SIGN! the use of a somewhat more toxic substance like avid, azamax or about a dozen others varying in toxicity but all highly effective will in essence destroy the invaders completely. A second application may be considered. After this go right back to the preventative maintenance sprays at CONSISTENT intervals. Consistency is the key here. Now you are employing an integrated pest management strategy (IPM). Using highly toxic and harmful substances as your sole pest and disease maintenance strategy is very undesirable for obvious reasons. Neither however is using the other end of the spectrum solely for pest and disease control. You may lessen the pressure or maybe even eliminate it if the area is small and compact, but in a larger area it’s unlikely you will eliminate it. Not impossible but unlikely. If you employ the more toxic options ONLY at the time they can be most effective (first sign of pest disease presence, It takes very little to treat an area with only a few thrips present. A light application for entire area.
I’ll say it again with proper cultural practice and maintenance sprays like for example Cease (bacillus subtilis), neem, Nuke em etc. can be VERY EFFECTIVE against pests, powdery mildew etc. when used in a consistent spray regime. Companies manufacturing the numerous safer alternative products currently on the market may combine plant based essential oils like rosemary, spearmint etc. along with other ingredients creating Environmental friendly sprays which act as very strong detergents to many of the pests that plague indoor cannabis growers. They can be VERY effective when USED CONSISTENTLY as part of a pest and disease maintenance program established ahead of time and ADHERED TO. Tweaks to the program can be made as the applicators go along to suit there specific facilities needs. Serious growers will implement an IPM program because it lessens down time and saves money in the long term. Whether it be a small 3 light grow or a large 300 light grow.
My apologies I tend to go off on tangents regarding what I am passionate about. I am definitely not implying that no one on this forum is aware of things like this. Not at all.
Please feel free to correct or add to my post. I don’t pretend to know a lot. The more I learn the less I know. Tu
