Help-Spider Mite Treatment not working!!
Comments (16)It seems to me the notion of "eradicating" mites is preposterous. The two-spotted mite has lots of hosts and is widespread in every garden. What is normal in most gardens is an equilibrium where you have some two-spotted mites on the roses, some predators eating them, and usually little or no noticeable damage. At times, weather conditions lead to a surge in the TSM population and you have a problem, starting on certain canary-in-the-coalmine varieties that you learn to identify and watch for danger signs. If I bring a potted rose that has been doing fine outside into my sunspace, it will have a catastrophic mite problem within a month unless I spray it with soap or oil frequently. The basic reason is lower relative humidity. The mites were there all the time but not causing a problem. Mite outbreaks are often caused by spraying insecticides which kill the predators of TSM. The use of Merit is known to cause an increase in TSM reproduction apart from the effect on beneficial predators. If an insecticide must be used, spinosad (for caterpillars, thrips, and sawflies) is best from the standpoint of mite control because it spares the predators. Mite outbreaks are favored by high temps, low relative humidity, and lack of rain as well as by use of insecticides. In areas with rainfall, roses planted under eaves are much more susceptible to mites. New potted roses may be susceptible to mites because mite predators were killed by sprays in the greenhouse. I can always find TSM on my roses, but I very rarely have a problem. That's because our weather normally doesn't favor them, and I don't use insecticides....See Moretiny spiders on houseplants, spider mites?
Comments (4)Spider mites are barely visible with the naked eye. Usually the back of the leaves on affected plants will feel gritty. By the time the webs appear you have a full blown case. Check the back of the leaves with a magnifying glass. I've had good results with spraying the plants with insecticidal soap, such as Safer's or using Trounce, also made by Safer's. Yes, spider mites will kill your plant if you let them. Here's a link to the houseplant forum. There are very some knowledgeable people there who will surely give you good advice. I don't know how to make it a clickable link; you'll have to copy and paste. http://forums2.gardenweb.com/forums/houseplt/ Good luck with your plants....See MoreAre these Spider Mites?

Comments (3)Thank you! Yay-- not that I'm happy about aphids, but I'll take them over spider mites!...See MoreSpiders or spider mites?
Comments (12)Oh whew...I am so relieved to read that nobody thinks they are spider mite webs. Whew, whew!! Is there some definitive way to determine mite webs vs spider webs? Thanks TJ. You are right. And I haven't sprayed a thing, good or bad, in the last 15 years with the mentality of "come what may" but this yard has been trying. I have never seen so many good and bad bugs in my life...and in the last month resorted to BT to kill the hornworms that are decimating my tomatoes and since I'm spraying anyway, I bought the neem which I'd read up on here. It appeared to be pretty innocuous overall, so that I used along one fence where most of my succulents live in light shade and dappled sun--that's the area where both of these photos were taken. None of it was sprayed on my edible or flowering plants, as I read that neem can damage blossoms... The only thing I have consistently used except when I lived in SF was snail bait and they seem to be having quite the blast anyway this year. Jean, we sure do! I can't confirm my neighbor ID'd what she saw correctly but upon hearing that and about two minutes before I ordered neem, lol, I did google it and Japanese Beetles were spotted in the Sacramento area, right above me, per the CA Dept of Ag. I only read one article but that was close enough for me! Ken, my spiders are year round, I'm afraid. January has much less than the other months but there is no month where I can't find spiders crawling on my plants or webbing here and there. Come spring, there's virtually no plant I can't find a spider on or at least evidence of some spider having been on it. That said, I still find it really bizarre that at this yard, for the first time ever in my gardening life, I have not seen ONE aphid. Spiders are not predators of aphids, are they? I've never seen a ladybug here either..probably because there are no aphids. Not complaining but I find it so bizarre! Thanks again, folks!...See Morebikerdoc5968 Z6 SE MI
