What is biting DS in bed at night??

[roses2]

DS is waking up each morning with ~1 bite each day. This has been going on for 3 weeks. In a different place each time. On his back, face, hand...

I've hoovered, boil washed the sheets.

Any idea what it could be? Photo of bite attached.

I don't think it's bed bugs because it is one bite only each time.

Hopefully it's sorted now.

But if anyone starts getting bites again try using a plug in mosquito repellant/killer overnight and see if that helps.

If someone is very susceptible to mosquitoes then they will be bitten in the UK when others around them aren't.
