Individuals want a home that is welcoming and comfortable. Unfortunately, many conditions that people find appealing also appeal to pests. Pests may be more problematic at certain times of year, such as when weather is extreme and pests like rodents or even raccoons seek refuge in a home. During times of year when temperatures are mild, certain insects may begin to hatch or swarm, becoming problematic around the home.

Some signs of pests taking up residence may be readily apparent, while others may be less obvious. The following are nine signs of pest infestation in or around a home.

1. Droppings: Small droppings may indicate that pests are nearby. Droppings will vary depending on the insect or rodent. It’s good to familiarize yourself with the appearance of various droppings, from mice to termites to bed bugs.

2. Footprints: Footprints are another sign of pest infestation. Footprints left in dirt around a home, or in dusty areas in the attic or basement, may show that pests are tracking in and out of the house.

3. Sawdust piles or trails: Sawdust could be indicative of termites or ants. Insects like carpenter bees also may burrow into areas of wood and leave sawdust behind.

4. Shed wings, skins and casings: Many insects molt and, during this process, will shed certain parts of their anatomy to grow larger. Roaches, bed bugs and beetles are some pests that might be scattering sheds or egg casings in a home. Termite wings are discarded once the swarmers choose a new location for the colony.

5. Foul odors: Musty or foul smells, particularly in hidden areas, may indicate pests are nesting nearby.

6. Unexplained noises: Scratching or scurrying in walls or floors often indicates pests are present.

7. Bites: Waking up in the morning with welts or red areas on the skin might indicate the presence of bed bugs or other biting insects.

8. Presence of nests: Those who can see nests in corners or undisturbed areas of the home likely have pests present. Rodents often use chewed cardboard, insulation, paper, and other scavenged items to create nests, according to exterminators.

9. Increased number of beneficial insects: An influx of spiders and other predatory insects may indicate there are plenty of food sources in the home for them to feast on.

Pests can be problematic, but homeowners who recognize signs of infestation can take prompt action.
