an interesting tid-bit on their lifecycle,
A female lays about 100 eggs during her lifetime. Depending upon climate conditions, the eggs hatch in as little as 2-3 days, and the adult stage is reached in 7-10 days. The females reproduction is greatly affected by climate and humidity with a significant difference in the days till their maturity dependant upon the temperature i.e.) egg to adult. For instance at 60 degrees Fahrenheit, it takes 30 days for the egg to become an adult, at 70 degrees 14.5 days and here is the astounding number - 90 degrees Fahrenheit they reach adulthood in just 3.5 days! So now imagine those populations increases over a month when the offspring start to reproduce less than a week after hatching - at 70 degrees she and her offspring number 13,000; at 80 degrees she and her offspring represent a staggering potential of 13,000,000 individuals over a single month - huge population increases!
Mites evaporate large quantities of water from their bodies, so they must **** juices from the plants. This is easier for them to do in a dry environment. Humid environments (above 60% RH) slow down their metabolism, life span and reproductive rate. Mites may be controlled somewhat by lowering the temperatures (at about 50 degrees Fahrenheit they start to hibernate), thus slowing down their life process considerable. Even if you only decrease the temperature during the indoor dark cycle (when it is easier to lower temperatures), the progression rate of the infestation is slowed considerable
I was recently doing a bit of online research on mites and came to a site at the university of indiana or something.
These folks said that mites need to transpire almost continually. They suggested using a bit of "wilt proof" on them as it slows the transpiration process down.
They also said that they have been successful using a mixture of 1/2 isopropyl alcohol to 1/2 water and spraying it directly on the plants making sure to cover entire surface top and bottom of leaves. let dry and then 15 minutes later hit them again with the same solution.
The site went on to say that they have seen very little harm to the plants treated and have had 100% success in killing the mites on the plants treated with this method.
