Could be a few things, bed bugs as pointed out. But they leave a smell almost like strawberries; oh and you can see them just pull up your matress and take a look. Very distinguishable, very easy to get rid of. And very common in northern ontario, and farther north here in Canada and Alaska. More then likely, it's fleas, or some other little critter like that; or another type of outdoor parasite, maybe mites of some kind, lice, etc. Easy enough a solution to get a indoor trap and see what you catch, take a look and take the correct solution to get rid of it.
Spiders only bite if you roll ontop of them, they are picky eaters. People are not a favorite food. This comment was edited on Nov 30, 01:55.
