Shield bug. Not a problem

Thanks Owdboggy I'll leave it alone then.

Good idea to leave it be. This one looks like a juvenile. They predate on other harmful bugs but also do damage themselves. They are also known as stink bugs and can squirt you with a repulsive nasty stinky juice of some sort. They are known to infest homes by the hundreds climbing the walls in plain view and congregating around windows. If that happens, you'll need to call an exterminator. If you try to swat at them, you'll get showered.

Oh that sounds pretty scary Bathgate but so far I have only seen this one. Lets hope it doesn't have any friends.

for info on UK types.
We have had these in every garden we have ever owned and never had any problems with them in the house or smelling when handled.

Are stink bugs dangerous? Stink bugs do not bite or sting and pose no danger to humans or pets. They are, however, a major agricultural pest and can cause a lot of damage to plants and farm crops. In addition to damaging plants, when inside of home's their odor can become very overpowering.

We too have had them in every garden and so far have never experienced any problems. Yours looks like a lovely Hawthorn Shield Bug.

you can keep them. thank you

Thank you all for your replies.

You are welcome. Can you believe it is snowing in New York

I've never come across anyone in Britain who has experienced any stink. Maybe American ones are either touchier or stinkier! Snowing Bath? Oh dear...

Well, I never came across a skunk that stank but i know they can and do. Wisdom is applied knowledge.
