The answer to 'spider damage' is that spiders do not actually cause damage to homes or property. Spiders are generally harmless and beneficial insects that help control other pests. However, their presence can be unsettling for homeowners, and some species may pose a risk if they are venomous.
The most common signs of spider activity include seeing the spiders themselves, finding their webs, or discovering egg sacs. While spiders don't cause structural damage, their webs can be unsightly and their presence may indicate other pest problems in the home. The best solution is to remove any spiders and webs, and take steps to make the home less attractive to them, such as sealing cracks and crevices and eliminating sources of food and moisture.
