i think i hold spider mites on my plant. we are supossed to get precipitation today so i brought it outside. the temps are in the mid 40s and lows around 35 or so. will this take out the spider mite.
Answers: No, it is unlikely that these temperatures will execute the spider mites. Insecticidal soaps or a 1-2% solution of dishwashing soap may kill the spider mites that these sprays contact, but they do zilch to the spider mite's eggs so the mites will return. Use horticultural oil on your plants. These lightweight oil are very out of danger to humans and pets, but they smother the mites and their eggs. Here is a great article from the Colorado State University Extension Service on the control of Spider mites: http://www.ext.colostate.edu/pubs/insect...
Additional Details: It has be suggested that you use Spectracide 3 in 1. Here is the sticky label for that product: http://www.spectracide.com/ProductCatego...
From the label you will see a alert that caution must be used when using this product on sensitive plants such your palm. Test this product on a fern before broad use. Also, this product is listed as one harmful to humans & pets. It must be applied outside if used. Finally, this product includes an insecticide. To be forceful, you should use a miticide not an insecticide. Mites are not true insects like spiders are not true insects. Insecticides do not enjoy the same effect on mites that it have on true insects.
Occasionally, my roses get spider mites. They're nearly impossible to waste. After trying several of the regular pesticides, a local greenhouse sold me some industrial strength pesticide that will kill them. Check next to your local green house. They should be able to point you to a pesticide that will do the opening without massacre your plat (you didn't say what type).
