I found a home made spray I use that literally melts the webbing, kills the eggs and the mites and helps the soil. It works well on aphids and thrips. Apply every 5 to 7 days
2 quarts water
1/4 cup each of tea tree and peppermint castile soap, I use Dr Woods as it is thicker
1 tablespoon hydrogen peroxide I use food grade but have seen the brown bottle store stuff used but it has other stuff in it
1 cup 70% rubbing alcohol
Mix first in warmish water then add cool to fill.
I do not recommend for peppers or arugula or any plant with tricombs although it can be used prior to the tricomb stage. This worked excellent in my garden this year. We were very hot and dry and loaded with mites. Two spot, spider, cyclamen and one I could not identify. My first applications were in 3 day intervals because of the amount of mites then 5 day then 7 days and then only for aphids. It dries fast even spraying to dripping. This spray helps to inoculate your soil. I have recommended in several chats and the reporting results have been excellent.🌷
