  Re: [Aroid-l] Spider Mites

I'm from Canada, so I don't know about the product names in the USA. There are few products that really do work with mites. Insecticides don't work as they're not insects, they are separate.... I have not found anything to work in the natural cure realm... like soaps, oils... I've grown orchids for years and two spotted spider mites are a real bane and can quickly destroy a collection. You need a specific miticide. Some you (in Canada at least) need a license to buy. First on my list is AVID (very expensive, but most effective). Next would be Pentac - slower, but also effective. Last would be an old product called kelthane. This is a nasty one and mites may have built up resistance. I say nasty as it does not break down quickly in the environment. The AVID may be expensive but a very little bit goes a very, very long way. One litre would last several people with greenhouses a lifetime I would
