How do I protect my indoor plants from thrips
So I have western flower thrips in my veggie garden. I’m keeping their numbers low so I’m not really concerned about the plants outside. I expect to coexist with some level of thrips every summer there. Indoors however I have a zero tolerance policy for thrips. Since discovering thrips outside I have been VERY diligent and meticulous to not introduce thrips inside and more specifically inside my plant room behind a door that’s always closed as well as windows that are always closed
Currently we are not opening our windows at all and are going to replace some of our window screens with 75 mesh no thrips screening. So far at least several weeks after discovering thrips outside I have not found them or signs of them in my plant room. Granted the plants I have indoors are generally less preferable to thrips( epiphytic cacti, air plants, and sanseviera) but of course it’s still possible. I check every single plant daily for any signs of thrips, I have blue sticky traps everywhere and so far nothing has been captured in them. I put bonide in all my plant room plants as a precaution although ive heard bonide doesn’t work on a significant portion of western flower thrips populations. I have spinosad, pyrethrin, neem, tons of 99.99% rubbing alcohol(that I dilute of course), acephate, bifenthrin, insecticidal soap, citric acid, and horticultural oils on hand if needed. Outside I have deployed predatory mites, pirate bugs, and nematodes(the ants are complicating that though), because the less I have outside the less likely they are to get it.
Other precautions are:
-changing my clothing before entering my plant room
-any harvests from outside must be placed in a ziplock bag BEFORE entering the house and immediately placed in the fridge. Herbs are to be dried out via the oven
- once a week I spray a mixture of neem, soap, and rubbing alcohol on my plants
Is there anything else I can be doing to protect my indoor plants. Also if the thrips do get inside and are the type that’s resistant to imidacloprid do I have any other options for systemics? I kind of assume especially with western flower thrips that I they get to my indoor plants they will never fully go away
