I've been getting these bug bites in the past little while. They look like flea bites, itch like crazy and last for several days. I have no pets. I have so far gotten bites around my abdomen and hips, on my arms and wrists, once on my hand. I usually get only one bite every few days, or sometimes every 2 weeks or so. This has been going on for some time now (several months?). I have checked my bed carefully (and vacuumed it, washed sheets in hot water, etc.) and don't see any signs of bed bugs (blood, droppings or bugs themselves). I have read that bed bugs are usually visible. I am guessing that if they are fleas or bed bugs, they would have multiplied by now to the point of visibility (for bed bugs) or more bites more often.. But I still only get one every few days or so.
Does anyone have any idea what is causing these bites? Are they common house spiders (i have seen a few in my house before)? Do spider bites itch like this and look like flea bites? I thougth spider bites might be more like stings though?
