I have one Nepenthes Rafflesiana that's growing great, but about a month ago I noticed SCALE on it! I've been scraping them off, but I went on vacation for a week and they came back with gusto while I was gone. Since I got aphids on 2 Sarrs around the same time I've decided to use Orthene or something, but first I'm wondedring if something cheaper would work, like 90% alchohol. The smallest bottle of Orthene I could find was $20, and I don't want to spend that much $$ on three plants! Can you please post what works for you in killing scale and/or aphids, all help will be appreciated! Also, if anyone knows where I can get a cheap($10-$15) bottle of Orthene, I'd definitely prefer that. Thank you!
