How long do cat roundworm eggs survive? - briefly
Cat roundworm eggs can survive in the environment for several months to years, depending on conditions such as temperature and humidity.
How long do cat roundworm eggs survive? - in detail
Cat roundworm eggs, specifically those of Toxocara cati, are highly resilient and can survive in the environment for extended periods under favorable conditions. These eggs are excreted in the feces of infected cats and initially require a period of development in the environment to become infective. This developmental process, known as embryonation, typically takes between 2 to 4 weeks, depending on temperature and humidity. Once embryonated, the eggs are capable of surviving in soil, sand, or other outdoor environments for months to even years. Their durability is attributed to a thick, protective outer shell that shields them from adverse environmental factors such as UV light, temperature fluctuations, and desiccation. In moist, shaded areas, the eggs can remain viable for up to several years, posing a persistent risk of infection to cats, other animals, and even humans. The eggs are highly resistant to common disinfectants and can only be effectively destroyed by extreme heat, such as boiling water, or strong chemicals like bleach. Proper hygiene, regular deworming of cats, and prompt removal of feces from the environment are essential measures to minimize the survival and spread of these eggs.
