Using this is relatively easy and provides one of the most effective ways to eliminate mosquitos at the source: just squeeze to measure the right amount and then drop into your sprayer with some water, mix, then spray. I far prefer this to an adulticide that kills lots of beneficial insects. You only need a little of this. I used 1 oz and spot treated 3 one-quarter acre parcels where there are potted plants, bamboo, tree holes, etc. I got my neighbors permission, which I think was easier because this has very very low risk of harm to mammals or insects. It does appear to cause some birth deformities to reptiles, so I try to be judicious about where I use it and when. I am planning to apply this every 21 days during seasonal times when there the conditions allow for mosquito development.
