"The only downside to organic insecticides is that they tend to have low persistence and require lots of reapplication."
S-baby..does it say to use a surfactant or not? Also, does it say it's safe to spray on plants?
I have a 100 acres at a wkend ranch and when applying any type of liquid spray, an agricultural surfactant is great for reducing the waters surface tension, thus helping more of the product to adhere to its substrate. Also, make sure you read the label and identify what plants can take this product, w or w out a surfactant. Sometime foreign substances on waxy-based plants can remove this layer which is a sun/UV protector I can also tell you that mosquitos love to bury themselves deep into the heart of most vegetation to avoid the sun/UV...These areas are critical for your application to get the pests out of your recreational areas.
Finally, one place that most people over look when trying to rid their place of mosquitoes is the drainage system. Go to the most remote drain, and about a gallon or two of liquid soapy water, and a little bleach for good measures...you have to dispense enough that will go thru the entire drain system and be able to the see the suds in the last drain screen before it hits your street or other. Does this make sense. Also, if you have gutters that have leaves and other debris in them, it traps water and provides a perform medium for larvae production...that goes w stagnant body of water that has 70-80% of daily shade.
Pls post how it works, and just like Neem oil, it may take multiple applications before you get the cumulative effect...bon appetite, tstex
