The answer to 'why is my spider invasion' is that spider infestations in homes are typically caused by a combination of factors, including an abundance of insects for spiders to feed on, cracks or crevices that provide ideal nesting sites, and a lack of effective pest control measures. Spiders may enter homes through small openings around windows, doors, or utility pipes, and can quickly establish nests and reproduce, leading to a larger spider population.
Symptoms of a spider invasion include seeing more spiders than usual, finding spider webs in corners or other out-of-the-way areas, and noticing increased insect activity, which can attract more spiders. To address a spider problem, it's important to identify and eliminate the root causes, such as sealing entry points, removing sources of food and moisture, and using targeted pest control methods. In some cases, it may be necessary to call a professional pest control technician to effectively manage a significant spider infestation.
