| Thrips
Thrips can severely damage the flowers of Vanda's. They will start their work even before you can see the flower spike coming out. They will also damage the roots of your vandaceous orchids. If you see indented rings around the roots of your Vanda's, that is the result of Thrips.
I grow Vanda's outdoors in Miami, Florida. Thrips are a constant problem in this environment. In this environment, I have found nothing that works except Orthene.
However, be careful. You must decide for yourself if you want to use a chemical like this.
Pros:
1. It is very good at controlling thrips. I use it once a month and I have no problems with thrips in an environment that is full of them.
Cons:
1. A toxic chemical.
2. It STINKS BAD.
3. Breathing and skin protection required to apply.
4. No entry into the sprayed area for ONE DAY after spraying.
5. You must READ and UNDERSTAND the directiongs for safe use.
