Seeing a rat or two isn’t uncommon, especially in mild climates. That doesn’t mean they are actively a danger to your home. The problem is when you start seeing rats regularly in your yard, there’s a good chance they are also looking for ways to get into your house or other buildings. All they need is a small hole or gap, and they have a new place to nest -- which is bad news for you. Stay cautious if you start seeing rats in your yard all the time. 

Homemade raccoon repellents can be a cost-effective and humane method for keeping raccoons off your property. Raccoons despise the smell of vinegar, so keeping a bowl of it near your home can keep them away. Some wildlife companies advise using cayenne pepper or hot sauce sprinkled near your deck or porch as another homemade option.

To keep wasps away from your home, you can consult with an exterminator about preventative measures and potential follow-up visits. For a non-lethal approach, consider installing a fake wasp nest, as this can deter wasps from building their own nearby. You can also use natural repellents. Wasps dislike the smell of substances like coffee grounds, cinnamon, and vinegar. Additionally, planting certain plants in your garden or in pots near doors can help repel them; these include eucalyptus, peppermint, lemongrass, and basil.

Some plants that are toxic to animals or insects are also toxic to people. Daffodils, for example, are considered poisonous to humans (although they are rarely fatal). Most of the other plants listed above, however, are safe (and delicious!) for humans to eat, including basil, rosemary, and lemongrass.
