Spider Mites :(

My beautiful banana was looking droopy the other day and yellowish on the edges. I hadn't had time to pay a lot of close attention to it lately with all the madness going on in my life. When I looked closely, I noticed all these little webs and MILLIONS of tiny white spider mites!!!! I almost dropped the watering can. I sprayed it vigorously with poison and then read the label on the bottle. I am dumb like that sometimes. When I read it, it said that it would kill all sorts of bugs but not Spider Mites! I guess the eggs are impervious to the oil in the spray. So I took the damn thing outside and hit it with a high pressure hose and blasted the little bastards. The tree looked a hundred times better, but the leaves are all pock-marked from where they were sucking the life out of it. I hit it with water every day for a week and now I am doing spot maintenance. It is so hard to control those mites, they just seem to keep coming and coming but the tree looks good again. I had to cut off about 5 leaves on the bottom that were just done. It has put out another leaf since then and is still nice and green so I think it has hope. I think it got the mites from a rubber tree I bought at Hannaford's. I didn't check it as well as I should have and I had it setting on the same table as the banana so it could get a good light and I have never had a single mite before. Luckily all the plants nearby the two trees seem ok...I dunked them anyway just in case! Soon I should have some pics of my plants to post here...just have to scan them since I am so behind the times and don't have a digi camera!
