Vents on the outside of a house help to regulate temperature and moisture levels inside the home. They allow fresh air to circulate, reducing the risk of mold and mildew growth. Vents also help to improve indoor air quality by removing pollutants and odors.
The vents outside the house are typically located on the roof or on the sides of the house near the ground.
House vents are typically located both inside and outside the house. Inside the house, vents are usually found in ceilings, walls, or floors to allow air to circulate. Outside the house, vents are often located on the roof or walls to allow for proper ventilation.
Bathroom vents typically go outside of a house through the roof or a side wall to expel moisture and odors.
The bathroom fan vents to the outside of the house through a duct or pipe.

Air vents on the outside wall of a house are typically placed to allow fresh air to enter and circulate inside the building. This helps to improve air quality, remove moisture, and prevent mold growth. Additionally, exterior vents are often located near appliances or equipment that require ventilation, such as HVAC systems or dryers.
Plumbing vents work by allowing sewer gases to escape outside the house through a pipe that extends above the roof. This creates a pressure balance in the plumbing system, preventing the gases from entering the house through drains or fixtures.
When you say "exhaust vents in your ceiling" I assume you are referriong to the heating and AC vents inside your house and not the roof vent on the outside used to vent the attic.

Vents to the crawlspace under a house can, indeed, be covered. But that creates a "dead air" space. Vents provide, well, ventilation. Consider why covering them is necessary. Some vents have screens over them to keep critters out but let air in and through. NEW ANSWER All vents that lead to the outside should be completely covered. An unconditioned crawlspaces has very poor air quality. Opening the vents just adds to the problem. When the outside temperature hits the crawlspace temperature, condensation occurs which results in excessive humidity. The correct fix depends on where you live geographically but is basically the same. The crawlspace does need air. It needs air from your hvac system. That is how to avoid dead air.
it happened to me it was a dead bird or a mouse i cant rember wich but it was inside of it.
