Sorry, the doorbell distracted me and I sent the last posting before I finished.
The second application of nematodes I used 6-6.5 grams per .75 gallons of water. The remaining 9-10 grams will get mixed for the third application. I water in nematodes once every 6-7 days. The last two orders I placed 2 weeks apart and I actually used about 37-38M nematodes during that month.
It has now been several days since I’ve seen any flyin’ fuckers in my house. I used to see several per day up until about a month ago. Also, I’ve seen no outside indications that my plants have either thrips or gnats for about 3-4 weeks.
I intend to continue using nematodes until it has been weeks since the last sighting. Even then, I’ll just order smaller quantities and keep using them. As far as I remember, I had those things in the house year 'round, but it wasn’t until last year that I was able to positively identify them as my long suffering problem.
