spider invasion!

[Anthonyox10]

So im growing all my veg on my balcony. And recently ive noticed a few little spiders (babies?) Pottering around. No bother!

But ive just looked at my tomato plants and i literally have, probably hundreds of these little spiders bunched up on one pplant with they webs going from stem to stem.

Do i leave them? Or do they do any harm?

I spose they would keep the bugs away atleast??

As long as they are not spider mites ( but you wouldnt see them easily...smaller than a grain of dust ) , as long as they are small spider size then I leave them as they catch the greenfly

Yeh i did google spider mites. But these are actually living on a web and also there is a large amount on under the lip of the pot. Im now worried as to where mummy spider is haha

Have you been watching Arachnophobia with the giant mother spider?

The female spider probably died after laying her eggs. I don't worry about spiders in the greenhouse & polytunnel - they're not detrimental to our plants at all

Its all good the following day they had all gone.
