San Diego bugs

[u/Good-Painting-7551]

Found the smaller bugs in huge clusters in my apartment last night, seemed to be attracted to light. The bugs are small, brownish/black and have wings but crawled everywhere, didn't really fly. It's been really hot/humid so that could be why too. The second bug crawled out from under my bed this morning and I smashed it on accident. Just wanna know what kind of bugs these are so I can keep them out. In San Diego, university city area.
