Anyone use these during spring and summer ? Have they worked for you or just a waste of money? I've thought of trying this in the past but I'm still unsure,I have a lot of roses that really seem to attract mites,thanks
I used both last year for soil dwelling root aphids. I looked into pesticides but I have some food production, chickens, pets, family all in the same space as my trees. Every poison I looked into had warnings and precautions that I just wasn't happy with. It's risky because the the root aphids can really kick the shit out of the trees but I tried.
No idea how effective they were but come repotting season in spring I may gain some insight.
I bought the nematodes and then bred a couple more generations on some grubs in Petri dishes. It was pretty easy but I left the last batch too long and lost the colony.
I have a feeling that given the open nature of our substrates that the mites may be more mobile and effective.
I just looked online for instructions and it worked. I have a microscope so I could check with that. Just got overly busy and neglected them in the end.
I've used them, but didn't really see a huge benefit, or proof that they were effective. However, I mainly used them on hot pepper plants that I brought into the house late in the year. Aphids LOVE peppers, so it may have been a case where the nemotoades didn't get a good enough foothold early enough to make a noticeable difference. I intend on putting a bougainvillea out this summer and intend on getting the nematodes started well before moving the plants outdoors.
