By Bone bass you should be sitting in average of over 150 health, meaning a deathsquito can't one shot you naked as long as you are eating properly. With iron armor even without blocking it should take 4 or more hits from one to kill you.
This tells us you're intentionally running into a dangerous area without bothering to eat decenly.
Furthermore you have access to a shield and can simply hold block to take next to no damage and swat them dead.
Even more so you have access to bows, meaning you can easily shoot them before they even notice you.
If you are unwilling to take proper precautions and prepare properly Valheim punishes you for it, it's not a run in blindly - button mashing - death has no consequences game.
