To ask for help to identify this insect - I'm freaking out!

[Sunny525]

Can anybody tell me what this insect might be? They are in the window frames and on the window sills.
I have tried phoning pest control people and they should be getting back to me, I've emailed them these photos but nothing back yet and my bug phobia is starting to kick in.
I also made the mistake of googling and have identified a lot of terrible things that it might be, I'm such an idiot for looking, I know I shouldn't have

Are there many of them? How big are they?

(Just looks like a little beetle to me.)

Can you give an idea of the size or put something next to it for scale?

I can't see the picture that clearly on my phone but could it be a May Bug? Used to get lots in my parents porch when I was a child.

Thank you for replying, I know it's silly to get worked up but I can;t stop thinking about them.

I don't think they are May bugs, they are about 1cm long....

So how many are there, roughly?

They are clustered in the window frames about 20 in each window

My partner has googled them and it has come up with a German cockroach or American cockroach. It looks cockroach shape. Google image the above cock roach and see if thats them

There are 300,000 species of beetles, but look at the pictures here...
en.m.wikipedia.org/wiki/Cockroach

I think it is a western conifer seed bug. I have had them in my house, although not in the quantities you describe, just individuals once in a while. So I didn't need pest control, just squashed them as I spotted them.

I really hope they're not cockroaches (just because they seem scary and a bigger problem?)

The conifer seed bugs look likely because it does have a greyish triangular bit on it's tail, agh....

I'm making my husband google them all now, I can't look at another insect picture, I don't even want to walk bare foot in the house now, which I realise is silly but any kind of infestation really freaks me out.

I'm hoping the pest contol man will get back to me with a solution. Our windows need replacing (which may be why they are such an attraction to beasties, rotting wood) and I have decided that I'm going for plastic or aluminium to avoid the wood attracting anything else!

Cockroaches don't have the nice chequered edge that OPs beetle has, and have much hairier legs. I wouldn't be worrying about cockroaches. Besides, anything messing around in window frames is quite happy about being in the light, which cockroaches aren't.

The western conifer seed bug has the chequered edge but is rather shield bug-ish in shape, and I don't think OP's is.

Yes I think it's a wood boring beetle... is it one of these www.londonhomecounties.co.uk/blog/woodworm-identification-11-types-of-2?
