The answer to 'why is my tick infestation' is that ticks can infest your home and yard due to the presence of wildlife hosts like deer, rodents, and pets. Symptoms of a tick infestation include finding ticks on yourself, your pets, or in your home, as well as seeing evidence of tick activity like eggs or larvae. To solve a tick infestation, you'll need to take steps to remove ticks from your property, prevent future infestations, and potentially treat any tick-borne illnesses.
For a serious tick problem, it's best to call in a professional pest control technician who can properly identify the tick species, assess the extent of the infestation, and develop an effective treatment plan. They have access to stronger pesticides and application methods that are not available to homeowners. However, for minor infestations, you may be able to manage the problem yourself through regular yard maintenance, using tick repellents, and removing tick habitats around your home.
