PIL and adders on property next to her house

[TheCatThatDanced]

We are going to see MIL in her house in a pretty village near Bath this weekend.

Her NDN have recently had a cottage demolished and are in the process of rebuilding it or another property on the site. NDN have informed her that the builders have told her they have found a nest of adders on the site but they aren't harming them - I think they are moving them.

If any of these adders escape into PIL garden is this likely and do they bite? I've been googling snake bites and adders can bite and be poisonous and of course thinking about my 2 DC (both under 10 but over 5) and the possibility for them to be bitten.

Am I panicking unnecessarily?

I live in a village near Bath too, and we have occasional adders, including a nest under our decking when my kids were 3&5.
I can confirm that they are really shy , and you only see them if they are recharging in the sun. They always make a hasty retreat.
Our neighbours dog was bitten in long grass but still lives to tell the tale.

How reassuring to read that the nest is being handled properly. Good builders! Some would wade in and destroy it. You sound imminently sensible OP and nice to boot. Hope you have a lovely stay away.

There are adders here on the South Wales Coast. I’ve seen a couple (as well as slow worms and grass snakes) but I’ve never heard of anyone being bitten, though. I’m not worried for my children, but my neighbours on both sides say their dogs have been bitten.
Mine hasn’t.

They’re not too dangerous, OP.

Good to hear the builders have gone through the proper channels, TheCat.
Re: adder colour - it can be very variable, but females(which are larger than the males) are often a russety colour, whereas the males tend to be more yellowish. I once nearly trod on a baby adder, about the size of a pencil, which slithered across my path in heath land.

Dogs get bitten here regularly, my dog escaped death by a whisker.

Whet6you are panicking unnecessarily or not Op I would be crapping myself.
I am terrified of snakes even shy ones that avoid people!!
( i know I'm not being heloful)

I agree
I saw a snake abroad and nearly shat myself
They terrify me!
I’d invite PIL to your house instead

Snake owner here. Snakes don't want to bite because it alerts you to them and will stay away from you rather than bite.

The reason dogs tend to get bitten is if the dog doesn't leave them alone so the snake feels like they have no choice but to defend itself.

If you just leave them alone, you have nothing to worry about.
