Woodlice in Abundance

DoneWorking

I have just noticed lots of woodlice at the entrance walkway to my garden 
Particularly after dark when there were scores of them scurrying around

I am concerned that these may start damaging my wooden garden fence 
There is some rot on the gate

I've also noticed a few in the house recently but assumed they had entered via my family 

Should I leave them alone
Or eradicate them

Woodlice don't damage wood unless it's already damaged, they are the cleaner uppers of mess. The fact that it's rotting is what drew them there, and any other debris, like rotting leaves or vegetation.

They are mostly harmless. If you have rotting wood, you'll have woodlice

If you grow strawberries, they do have a taste for them

Harmless and useful. Mostly female.

If you have rot starting that will attract them or lots of dried leaves and such hanging around.

Totally harmless, if inside scoop them up and give them a flying trip outside. They probably are coming in on clothing if they are around the entrance. Give it a good sweep and clear the area.

Everything is here for a reason, woodlice, ants wasps,beetles, are all natures waste disposal units. Night time is when they enjoy freedom to move about uninterrupted  by human activity. They clear away rotting vegetation and waste. and when weedkillers are used it destroys the habitat that is needed for bugs to survive leaving them for dead essentially -  
DON'T  kill bugs, DON'T use weedkillers and DON'T  use slug pellets because of secondary poisonings.

We used to get them in our sunroom. There must have been a small crack somewhere they were getting in through, we'd find corpses as it was so dry in there they didn't last long.
