They're mighty Mite-y, and they're letting it all hang out.

With apologies to The Commodores, I just wanted to let people know that this extreme heat and drought has created PERFECT conditions for spider mite populations to explode. They love heat, and they hate moisture. I am seeing mites on not just "the usual suspects" such as my Datura, but all throughout the ecosystem on trees, perennials, annuals, vegetables. Some poetic justice, I guess, but I've seen a number of weeds even heavily infested.

If you're seeing plants that look like this (not my photos), they have mites:





For light infestations, repeated dousing of the undersides of the leaves with water will help. If it gets more serious, you may need to explore other options.

3. Here's an article on biological control using ladybugs and "predator mites"

I think a lot of this is still in the experimental phase, not widely available to end consumers (home gardeners).

4. Had them on 3 miniature roses I kept on the porch; gave up!

Large rose bushes may have some, but also some other creepy crawlies which eat HOLES in leaves, leaving them like skeletons! OH MY!

5. Little buggers took out my pretty Columbine plant earlier this year and they are besieging my

green beans. So far, these are their only victims, but I'm nervous.

6. I am sure that some may have a problem with this remedy,

but I make a "tea" from tobacco and spray it on plants with spider mites. It has always worked for me for most pests I have had, but I don't use it unless I have a serious problem, since I don't normally use any chemicals that will harm beneficial insects. I used this one year for white fly infestation and I have never had white flies since. I understand that this is a dangerous chemical to use, and never use it on or around tomatoes.
