The answer to 'why is my mulch pests' is that mulch can attract various pests if not properly maintained. Organic mulch, such as wood chips or shredded bark, can provide a moist, inviting environment for pests like insects, rodents, and even snakes to thrive. This is because the mulch can harbor decaying organic matter, which can serve as a food source for these pests.
To prevent pests from taking up residence in your mulch, it's important to maintain the mulch layer and keep it from becoming too thick or compacted. Regularly rake and replenish the mulch to ensure proper airflow and discourage pest activity. Additionally, choose a mulch type that is less attractive to pests, such as pine bark or gravel, and avoid using mulch that is already infested with insects or other pests.
