Mosquitos were feasting on my yesterday. Usually they go for people around me, but yesterday I was on the menu. I can’t remember the last time I had itchy mosquito bites. This morning I woke up with four. I tried putting some hydrocortizone/aloe cream on them, but it doesn’t seem to help. I also took an antihistamine, as I’ve heard that is supposed to help.

Anyway, is it normal for itchy mosquito bite bumps to manifest themselves a full 24 hours after being bitten?

My mosquito bites show up a few minutes after being bitten and the bump dissapears in about half an hour.

They do seem to itch more this year. Maybe the insects got an upgrade. 🙂

All the mosquito bites I’ve had usually swell up within a few minutes of the bite and start to go down in an hour. Are you sure it was mosquitoes? There are a lot of other biting insects which have cause similar reactions, with differences in the itchiness, length of bump, etc.

Definitely. For example, I felt a bite on my finger. I looked down to see a soon-to-be-deceased mosquito there.
