This Grist article speaks to the fact of more insects invading our homes and I can personally say, it's true.
I've lived in this house since 93 and have
never been bothered with black widow spiders.
So far this year? I've killed 5.
(I know, they're a part of the circle of life, and have their purpose but they can cause horrible pain, so forgive me,
but I killed them.)
And the heat and drought are causing all kinds of other problems too. Planes are being stuck in the tarmac
at airports, because the asphalt was so hot, it melted around the tires. OMG.
Cooling ponds at nuclear facilities are becoming overheated and that could be a huge issue.

Roads buckling, twisted train tracks.
It's not just the crops although that is the main concern, and the rising prices from lack of product to market.
