Aphid infestations happen when aphid-attracting plants like mustard and nasturtium are present, there’s a lack of predators, or plants are weak. Avoid plants that aphids love, and consider increasing natural predators that keep aphids at bay. Birds, wasps, and ladybugs play roles in balancing out aphid infestations, so add pollinator plants and habitats to your yard that attract birds and other aphid predators.

A bowl of vinegar will not kill fleas and acts only as a repellent. To get rid of fleas, you can create a homemade flea trap or buy flea traps from a local hardware store. Consistent trapping and meticulous cleaning will help eliminate fleas before they become an infestation. If you have a moderate to severe flea infestation, you’ll likely need the help of a local flea control specialist.

Roaches may not be quite as common on the top floors of a home, but they can easily climb up there if they want to. Second stories are less likely to have food sources and somewhat less likely to have moisture issues, so most roaches are attracted to bottom levels first. However, humid attics and similar spots can help roaches thrive.

Roof rats are relatively small rodents that typically measure around six to eight inches in length (excluding their long, scaly tails that are often longer than their bodies). They have sleek black or brown fur, pointed snouts, and large ears. In general, they are typically smaller and darker in color than common brown rats.
