agreed. Just stop using it for 3 days before harvest. you may also wish to dip your plants in lukewarn water to wash away any residual and/or bugs, dirt, dust, etc. do this just before hanging for their first dry
It kills the adults and anything that has hatched. The active ingredient breaks down within a few hours. It is odorless for the most part. Problem is eggs remain unaffected. They hatch in 1-3 days so a bomb each night for 5 days seems to knock them back to nothing. But as with life, some tough guys survive to continue the battle. So be prepared to deal with it.
The easiest thing to do is get floromite. It reamins checimally active for 3 weeks. So cant be used at end of harvest. But with planning, use when small and spray ever 3 weeks. The last spray should be 4-5 weeks into flower. Target only the leaves as best you can. Drench the leaves with water with no hot lights until they dry out.
Some people argue you should never spray after flower. Fact is this stuff is checimally inert (breaks down and has no chemical propeties) after 3 weeks. It is approved for used on commerical crops already harvested. So it should be pretty safe.
