Fig tree pests

Hi....I have a small fig tree.  It was outside initially, but I couldn't decide where to put it where it would withstand the cold over winter, so I brought it into the conservatory.  When it was outside, the leaves dropped of in autumn, but after I brought it in the leaves grew back.


There are 3 branches, 2 are fine with healthy leaves, but the 3rd branch obviously has some kind of pest problem.  The leaves are grey areound the edges and slightly mottled, eventually they curl up and drop off.  I can see very fine webs from the leaves to the branch and loads of really tiny insects in the webs.  


Does anyone know what they are and how to deal with them?  Many thanks.

    hi Sam, it sounds like spider mite to me . Do you have heating in your conservatory ?

    Have a look at this link.

    I've read your link and googled images of spider mites and I'm certain thats exactly what they are.  I've been researching fig tree pests for hours and spider mites didn't come up, so I'm really pleased to know what they are, thanks so much!

    Are they difficult to get rid of?  Can I use washing up liquid solution?  I noticed it mentioned a surfactant pesticide...

    I think I used Bug Gun when I had them on one of my houseplants but can't quite remember. Think it was. The trick with spider mite is to treat the plant asap

    Good luck. image

    I'll give it a go.  Many thanks again image

  • Spider mite can be difficult to get rid of and are often resistant to common pesticides.  If they survive the assault with Bug Gun, keep spraying the plant daily with water as they don't like high humidity.  I had great results in clearing a greenhouse infestation by using a predator mite (Phytoseiulus) but the temperature must remain above 20C and they are expensive!  I've also found a spray called SB plant invigorator to be pretty effective too.  That one also acts as a foliar feed.

    Hi Bob, thanks for your reply.  I've just noticed that the mites have moved over to one of the other branches now, unfortunately.  I looked at the predator mite, our conservatory is pretty cold so I don't think they'd be much use there at this time of year.  I'll look at SB plant invigorator, after the bug gun (if it doesn't work).  Really hope the fig doesn't die, I regret bringing it in now, presumably the mite would die over winter.

  • Yes, they're really a 'glasshouse' pest and only rarely cause a problem outside in the UK.  I get them occasionally on a clematis called "cartmanii Joe" which needs to be kept in my conservatory for much of the year, but putting it outside over the summer generally clears them (probably all of that rain we usually get!)  The mites can overwinter in cracks etc., so there's always a chance they will come back.  Good luck with your fig, Sam!

    Thanks Bob, could I ask one more question?  If I move the fig back outside, would it kill the mites?  Would the fig survive the cold after being inside and the leaves regrowing?

  • I'm in the process of trying to rid my 4 figs of spider mites now.  I've washed all the leaves with Natria insect and mite control spray.  Well it didn't spray so I poored it into a dish and sponged it on the leaves.  I'm going to take the advise of another message board and spray with water with a little alcohol and hope for the best.  I'll let you know how it works out.

    Well, sadly the fig is definitely dying.  The mites are back too.  I'll know better than to bring a fig in over winter next time.  I'll bubble wrap it instead!  Thanks to all for your advice image
