I have tried nematodes twice, the first time I tried them I don't think they arrived in a viable condition and the yellow sticky traps were all that worked, the second time was actually on the house plants in the rest of the house and the nematodes took care of the issue,,, a 50% success rate sure didn't justify the price.

Depends on who you get them from. Arbico, Nature's Good Guys, and Koppert's tend to have the best IPM products. Also have to keep the medium moist longer for them to be effective.
