How Do worms and maggots get into air tight coffins?

Worms and maggots can enter airtight coffins through various means, including small openings or flaws in the coffin's construction, such as gaps around seals or joints. Additionally, if the coffin is not completely airtight, insects can lay eggs before burial, leading to maggots developing inside. In certain cases, the decomposition process can produce gases that may create pressure, allowing for small breaches. However, it's worth noting that completely airtight coffins are rare, and even the best-sealed ones can eventually succumb to environmental factors.
