1. Rats

What to do: First, ensure there are no holes or cracks in the exterior of your home. If you have ivy on your walls, you might need to remove it, as rodents can use it to climb into your home. The main advice is to keep your home clean and dispose of all trash properly. Dirt and the smell of garbage are major attractants for mice and rats.
2. Snakes
It’s usually harmless snakes, such as garden or tree snakes, that crawl through the pipes. These snakes are slimmer than venomous ones, allowing them to fit through the narrow pipes. However, there have been instances where larger snakes, like anacondas, have appeared in people’s toilets in South America and Australia.

4. Spiders

This typically occurs in outdoor toilets without plumbing or sewer connections, where these venomous spiders thrive due to the abundance of flies for food. Therefore, it’s essential to check the seat thoroughly before using an outhouse toilet. Venomous spiders like the black widow, brown recluse, and hobo spider can bite without difficulty.
5. Opossums
To prevent opossums from entering your home, begin by conducting regular inspections of your house. You can also fix any gaps or holes that could be entry points for them. Your vents might also need to be covered with a mesh covering. If opossums still manage to get inside, it’s best to contact professionals to handle the issue safely and effectively.
