Pest control regimen/suggestions

4 years ago
last modified: 4 years ago

I was worried about a pest outbreak this winter and it's happened. Spider mites (or flat mites, but I'm petty sure it's spider mites) on several cacti, mealybugs here and there, and something I can't quite identify on my Graptopetalum rusbyi.
The spider mites are more established than I'd like. I only noticed the damage and confirmed their presence about 2-3 days ago and have been treating with a 50/50 water to 70% iso spray every other night to try and knock down the adult population.Mealybugs are... around. I don't find them often, but I know they're there.The last thing though I'm worried might be thrips (western, maybe?) on my G. rusbyi. They're small, sort of long-ish, and a sort of orangey-tan color. Not very fast, but not exactly slow either. I know that's vague and I apologize.
We're getting ready to move in 2.5 weeks so *of course* this is happening now. Right now I'm looking more for a systemic based option and am trying to decide what would work best to cover my bases. I've got just a bit on my plate right now and would really appreciate any suggestions or recommendations. Was looking for maybe a pyrethrin based option as I've heard (not read anything conclusive so, grain of salt and all that) that Imadacloprid based products can somehow increase the reproduction rate of spider mites. Any info on that, just for sating my curiosity mainly, would be appreciated as well.
Summary (bc it's late and I ramble)
Have: pest issue (spider mites, low poplation of mealies, and something not IDed but potentially thrips)
Want: systemic suggestions. Pyrethrin vs. Imidacloprid?

    And of course I made an error in the title. Perfect.

    Tj, I appreciate it but unfortunately I'm on mobile and the setup of houzz is not great on mobile. There's no edit option, only options to comment/share.

    I just experienced a similar situation where I couldn't pinpoint the exact pest I was dealing with, as I mistakenly didn't segregate a new succulent before repotting and putting it out front with all my other plants. I had webbing on some, others had issues closer to the root, ect. I researched extensively and was so frustrated that I finally just decided to do everything I could think of to fix my plants because I was so devastated. By the end, I ended up doing several different things to about 25 succulents of various kinds and sizes. First, I sprayed all of my plants with a dawn/ water solution as well as sprinkling with Diatomaceous Earth when they were dry. When it was clear that this wasn't enough for maybe 18 of the plants, I took them out of their pots, cut away any rotting areas, including roots, stems, and leaves. Then I sprayed them down with rubbing alcohol, really saturating them and wiping off the leaves and stems. I used a clean paper towel for at least each plant, usually multiple as to not spread any pest or possible disease. I also kept any healthy leaves and stem pieces that may have fallen off during this process to propagate later. I placed each plant on a paper towel on a cart, mainly because I have cats, and wheeled it into a sunny room where they couldn't get to them. I checked daily for weeks to make sure I didn't see new webbing, pests, black spots, or signs of further rotting. I misted roots with water occasionally. At the same time, I began dumping the soil out of the pots (sadly because everyone received my fresh soil mix a few months before this happened) and I sanitized the pots. I slowly began repotting each plant and kept them all away from each other until I was sure everyone was healthy, which of course ended up coinciding with having to bring them in for winter. The process took months, and quite a few of my plants decreased in size from having to cut away so much of them, but I ended up only losing one whole plant with this ordeal. I'm impatiently awaiting for more consistent warmer weather to see my plants thriving and growing again!

    I'm so sorry for the long post not being formatted into paragraphs. I had to type it in another app as this one is giving me issues typing anything out. I guess the formatting didn't translate when I copied and pasted my reply. :/

    Lyn S - just a question: you said..."cut away any rotting areas, including roots, stems, and leaves"...so did you have rot on top of pests?

    I don't have any suggestions because I never used any systemic; but some ppl do. I wouldn't just use everything I could think of on all plants. JMO, but it is best to use appropriate spray for each pest. It is recommended to blast off spider mites with strong streem of water. OR, to use neem oil or insecticidal oil or miticide. They need to cover the mites competely to kill. This may be better to use in your situation. I wouldn't bother with home-made remedies; it is difficut to measure exactly & it could be too weak or too strong. (And I would stay away from using any soaps/dish washing liquids unless they are plant-based.)

    Hope that someone using systemics will chime in...

    Yes, I believe one of the pests I had was mealybugs. :( I found a few on and in some plants. That's why I used rubbing alcohol finally. I forgot to add that I also tried neem oil.








































    Also, I use Dawn and water regularly on all my plants and lawn, especially in the summertime. Fleas can be horrible here. I also constantly use Diatomaceous earth all around.
