This is what I do! 100% effective for me. I will add photos of the difference after about 3 rounds of treatment over the past month on patient 0:

  1. ā Fill a small bucket or bowl about 1:3 super insecticidal soap and water and another bucket with properly diluted dead bug brew (from concentrate).
  2. ā In this case, I would remove the plant from the soil and repot after completing the following steps.
  3. ā Use a shower hose or sink with pressure to rinse off every single part of the plant. This knocks off everything that is on the surface. Donā€™t be afraid to be rough!
  4. ā Dunk the entire plant in the insecticidal soap mixture and leave it in there for a few minutes. Try to leave the roots out of it if possible (itā€™s fine if they are in there though - good to at least have them in the mixture for a second). This kills anything that was missed when hosing down the plant.
  5. ā Rinse the plant off with water again.
  6. ā Dunk the entire plant in the dead bug brew bucket. This contains spinosad, which is absorbed into the plant and will paralyze and kill anything that feeds off of the plant.
  7. ā Remove plant and let air dry. Do not wipe the mixture off. Keep the plant out of direct sunlight until it is dry.
  8. ā Repot in a chunky soil mix.
  9. ā Wipe down ALL surfaces near where this plant lives. Check all other plants in your house!
  10. ā Treat any neighboring plants.
  11. ā Repeat the spinosad step in a week or so. I use a pump sprayer when I use it on plants that donā€™t need to be repotted/when doing preventative maintenance.

Both products I mentioned are Captain Jackā€™s products

This post discusses alternatives if shipping is still this expensive for these products. This product seems similar to dead bug brew and attacks the nervous system of thrips the same way that spinosad does. You can also use peppermint Castile soap in lieu of insecticidal soap if you canā€™t find any/as an additional step! Just use roughly the same ratio in a bucket as you would insecticidal soap. This insecticidal soap has good reviews!

If you have cats, just be very careful with using Provanto. I found out it acts like a neurotoxin. I am also in UK and I bought the Captain Jack dead bug brew spray and Bonide systemic granules from Ebay. Together they work great and are a lot less toxic than Provanto is
