How do I know if these bites are bed bug bites or spider bites?

spider bites swell up… my guess would be bed bug bites. to make sure: at night time once the bedroom has been dark and you’ve been on it for a while turn on the light n check the mattress for bed bugs. u must check on the creases where the bed is sown… all along where the thread is. thats where they usually hide. make sure ur on the bed long enough before checking… they come out when they feel body heat

Bed bugs bites usually don’t show up because there microscopic if you are covering your bed that might be because of bed bugs I’ll explain when covered billions of them get trapped in one general area till it is enough for millions biting for it to actually be visible to our eyes but they can’t hurt you if not all trapped but spiders like dark areas like under your bed covers and the bed itself so I lift my covers up and look every night because one of my friends got bite it was the most disgusting looking thing ever and it took a month to go away.

If you have red welts with white dots in the middle…bed bugs.

no because people can have an allergic reaction to bed bug bites (which is common) and they swell up

Most people have a reaction to it. About 30% of people can get bit by bed bugs and not even know it or have any marks until they’re sick from the diseases bed bugs can carry.

you most likely have fleas in your house and they have been biting you. If you itch them and them begin to swell more im pretty sure you have flea bites. Also bed bugs are extremely small and are rare to get bit by them. Spider bites will usually hurt and swell as well… like i said its most likely fleas though

if it’s a bed bug bite ten there will be three marks in one general area if it’s a spider bite then,it’ll have one or two marks and it will swell depending on what spider you were bit by,probably nothing big,i wouldn’t worry
