The caterpillar-like parts on your wall are likely tent caterpillars. These caterpillars are known for building silk tents in the branches of trees and shrubs. They are often found in groups and can defoliate trees if their population becomes too large. It's important to monitor their presence and consider removing them if they are causing damage to your plants. **

To remove the red plastic parts from your wall, you can start by using a putty knife or a flathead screwdriver to gently pry them away from the wall. Be careful not to damage the wall surface while doing this. If the plastic parts are attached with screws, you may need to unscrew them first before attempting to remove them. Once the plastic parts are removed, you can use a wall patching compound to fill in any holes or damage left behind. Sand the area smooth and repaint if necessary to restore the wall to its original condition. **

Before painting the wall in your rental apartment, it is important to check your lease agreement. Some landlords may allow tenants to paint as long as they return the wall to its original color before moving out. Others may have specific rules or restrictions regarding painting. It is best to communicate with your landlord or property management company to get permission and clarify any guidelines before making any changes to the apartment. **

The exterior wall of the rental apartment may be cold and damp due to poor insulation and ventilation. If the insulation is inadequate, the cold air from outside can penetrate through the wall, causing it to feel cold. Additionally, poor ventilation can lead to moisture buildup, which can make the wall feel damp. It's important for the landlord to address these issues to ensure the comfort and well-being of the tenants. **

It is possible to repaint only certain parts of a wall, such as touch-ups or small sections, without it being too noticeable. However, if the area to be repainted is large or if the existing paint has faded or changed color over time, the difference in color or texture may be noticeable. It is important to use the same type and color of paint, and to blend the new paint with the existing paint as seamlessly as possible to minimize any noticeable difference. If in doubt, it may be best to repaint the entire wall for a consistent finish. **

To repair a 1 cm hole in the wall of your rental apartment, you can start by cleaning the area around the hole with a damp cloth to remove any dust or debris. Then, fill the hole with spackling or wall putty using a putty knife, making sure to smooth it out and fill the hole completely. Once the spackling is dry, sand it down to make it smooth and blend it with the surrounding wall. Finally, you can paint over the repaired area to match the rest of the wall. Be sure to check your lease agreement or speak with your landlord before making any repairs to ensure you are following the proper procedures. **

The parts that can be embedded in items like wall panels to hang them on the wall using hooks or angle screws are called wall mounting brackets or wall hangers. These brackets are typically made of metal or plastic and are designed to provide a secure and stable attachment point for hanging items on the wall. They come in various shapes and sizes to accommodate different types of wall panels and hanging mechanisms. **

To register a second residence in a rental apartment, you will need to check with your local government or municipality to understand the specific requirements and procedures. In some places, you may need to provide documentation such as a lease agreement, proof of address, and identification. It's important to communicate with your landlord and ensure that they are aware and approve of your intention to register a second residence in the rental apartment. Additionally, you may need to update your address with relevant institutions such as the post office, banks, and government agencies. **
