I am new and have a problem with thrips!

First let me say "Welcome to Orchidboard"!

I spray with Orthene for thrips. You have to spray once a week for three weeks to really get rid of them.

I try not to spray the flowers and do it in the early morning or late evening when the plants are cool. Add a drop or two of dish soap in with the Orthene.

I have never used Malathion, so maybe others will be along to comment on that.
