Don't let "good enough" be the enemy of perfect.
Where do you buy it?I sprayed this 3 years ago when Wasps and Carpenter Bees got bad. Took care of the majority of them. Sprayed again a couple months later and they were gone. Have a few Carpenter Bees popping up now. Going to spray when the weather settles down. THis stuff works.
Does it require an applicator's license? (I used to have one for personal use.)
