How do you know when you have bed bugs?

Its a spider bite. It’s only one or two bites at a time, they look like mosqito bites that you scrachted too much or a bee sting? If so its likely a wood spider , there brown with hair and can grow as big as a baseball. They look like a tarantula and the only difference is that they aren’t poisenous, but they do leave big red itchy marks when they bite. Spiders are very teritorial and this one has apparently claimed you’re bed as his home. I bet that you’re bed is near the corner of your room where it is easier to make a nest. Clean you’re entire room throrougly and was all your bedding and pillows in case of eggs. If your bed is in the corner, pull it out and clean the corner to make sure there is nothing it can live in like under a pillow that fell or a book leaning against the wall. However, if you don’t find a spider it could be a beatle. Water beetles bite but it depends on where you live. Wood spiders live anywhere but certain beetles that bite only live in certaon places. Either way, close the door to youre room most of the time so that if they are in another part of your house, they don’t go into your room. Close your window especially if you don’t have a screen in it. Lastly, keep absolutely no food of any kind in your room, don’t even spray perfume, put it on in your bathroom. It is absolte;y not bed buds because they leave dozens of tiny red dots on your skin at a time. Razor bumps from shaving also leave dozens of small red dots in a cetain area. The reason I know so much about this is because it has happened to me a few times. Good luck!
