Strawberry disaster

Well, having had three good years of strawberries, and then planted new plants this Spring, everything seems to have gone wrong!!

It started off very promising. The new plants seemed strong and we were getting a good number of flowers. And the first few strawberries were large and tasty. But in the last 2 weeks, I have been fighting a losing battle...

At least 50% of the fruit has rotted before it has ripened. And much of the remaining fruit is getting eaten by something!

I guess the rotten fruit is due to the almost non-stop rain we have had here for the last 2 months, but I can't work out what is eating the rest. I have found some very small slugs, but I am not sure they can account for the devastation, and I have slug pellets down; and the crop is netted against birds and mice. Each fruit is being eaten in a network of lines about 2-3mm wide taking off the surface layer of the fruit.

Any ideas, to see if I can salvage a few fruit for us?

I don't think so. Anyway, I think the birds have all drowned...

Do woodlice eat strawberries?? I just went out to try to salvage some fruit for tea tonight, and there was a woodlouse under one...!

I had squirrels gnawing on my strawbs leaving marks as you describe. They also bit off some and just dropped them.
My plants are in troughs under net but they ripped/bit small holes and got access.

Field mice like to nibble mine.

The wet weather has virtually annihilated my crop.  I've just been out now (as we have a rare break from the rain), but as you say, the majority are rotting before they're ripe.  In addition, I've found some are infested with a horrible thread-like worm - very thin, literally like a piece of cotton ... anyone know what it might be?
