Dowels are typically used to provide additional support and stability for items being hung on a wall, such as shelves or heavy artwork. While it is possible for dust or debris to accumulate inside the drill hole where the dowel is inserted, this can usually be prevented by properly cleaning the hole before inserting the dowel. Additionally, using a slightly smaller drill bit than the diameter of the dowel can help ensure a snug fit and minimize the space for debris to collect. **

Dowels are typically used to provide additional support and stability when anchoring items to a wall. When a dowel is inserted into a drill hole, it expands to create a secure fit. While it is possible for dust or debris to accumulate in the hole during the drilling process, the dowel itself should not hold any strange stuff once it is properly installed. It is important to ensure that the drill hole is clean and free of debris before inserting the dowel to ensure a secure attachment. **

The green stuff on the wall is likely a combination of algae and moss. Algae are simple, plant-like organisms that can grow in damp or wet environments, such as on walls or rocks.

Both algae and moss play important roles in their ecosystems, such as providing food and habitat for other organisms, contributing to nutrient cycling, and helping to prevent erosion. However, when they grow on walls or other surfaces, they can be unsightly and may cause damage if left unchecked. **
