    Hi, I found time to get the greenhouse cleared today, I'm wanting to re-oil the decking to protect it for this season, but before I do that I'm wanting to give it a good clean, I noticed through the summer lots of spider mite around,

    What's the best thing to use please.

        @martin-f the best thing to get rid of spider mites is to clean someone else's greenhouse! Mine is such a mess that it looks as if it has been ransacked, and I have zero chance of getting out to do anything about it for the next while! Any chance you could nip up the M6 and help me out, and I (would like to) guarantee your spider mites will magically disappear :roflol:

            Martin at one time I used Jeyes for cleaning my greenhouse . There are doubts on the effectiveness of its new recipe. I just use a strong solution of bleach now.
            The many chicken keepers on here may be able to advise a more effective cleaner....

              I use Jeyes fluid to clean out mine, not sure if it kills Spider Mites though.

                Red Spider Mite is completely different to Red Mite .

                RSM suck blood from plants, Red Mites suck blood from poultry.

                  I read that a mixture of water and isopropyl alcohol is quite effective. Kinda reminds me of hand disinfectant. I did use a bit of that in one of my indoor areas with limited success but I would imagine it would work very well if I really sprayed the stuff about when the area is clear of plants.

                  Outside, I never hesitate to get handy with the bleach. My greenhouses sit on a deck so the run off just goes down below onto the gravel. Think I'll be pulling everything out them this year and giving a good scrub before putting all the seedlings out... that won't happen until the end of March. Too cold until then to chance it.

                    Many thanks for all advice, ill give it a good scrub and put some jays fluid down and on the windows, I will be oiling the base after its dried out so that will kill anything on the floor.

                      I've been using this, last summer and autumn on RSM, it works.

                      Johnsons Cage And Hutch Spray 250ml Aerosol | Pets At Home

                      I've even sprayed ornamental plants with it and not noticed any damage, I know it is not for use on plants but us little people are not allowed to have the stuff that actually works anymore, in plant sprays.

                      This kills the eggs as well, anything that doesn't is a waste of time IMO.

                        @martin-f .
                        Will you be putting plants back in afterwards???

                        If you are the chances are the eggs are on those plants and will just overwinter.

                          To be honest Pete I don't know what ill be putting in,

                          It was late last year when I finally got the greenhouse in use, my main intension for the greenhouse was and still is flowers only,

                          With it being quite late on I just put some veg in, thinking to myself I will have a good read and decide what flowers I want to bring on in the greenhouse then plant out, have a good selection for different months so I'm not stuck with borders full of the same flower all summer,

                          But ive never found time to do it so ive got to act quick and get some seeds started off asap, so what will be going in is fresh compost for seeds in trays

                            If you are not returning plants that were in there last year, there is no chance of contamination.

                            I even doubt that RSM would be lurking on the timbers or framework of the greenhouse, it is usually passed on from year to year by plants.

                            As I use my greenhouse mainly for overwintering pot plants, RSM has always been a yearly problem for me.
