Skin bumps that look like mosquito bites

Lately, I’ve been noticing these little bumps appearing on my skin—just in a few specific spots. They look exactly like mosquito bites and they’re incredibly itchy. What's strange is that they tend to cluster together in certain areas; right now, I have about five or six of them just behind my knee. Does anyone have any idea what might be causing this? It seems unlikely to be mosquitoes given the season here, and I did wonder if it could be spider bites, but that feels equally improbable since I don't see any spiders anywhere in the house. 🤷

It’s entirely possible you've got bed bugs in your mattress.
They feed on human blood at every stage of their life cycle. During the day, they hide away in dark crevices, then come out to attack at night. These things can go without a meal for up to six months, and once temperatures drop below 59°F, they pretty much go dormant. They don't actually cause or transmit any diseases. (Wikipedia)
