What Do Ants Eat in the House and What Attracts Them?

Ants are a common household nuisance in kitchens and pantries. Ants are driven indoors primarily by their search for sustenance. Understanding what attracts them to indoor food sources is the first step in preventing their presence.

What Attracts Ants Inside

Ants are opportunistic omnivores that require a mix of proteins, carbohydrates, and fats. Sugary foods are a primary attractant, providing a quick energy source for foraging ants. This includes items like honey, syrup, fruit, candy, and spilled drinks.

Protein-rich foods are essential for the development of ant larvae and the queen. Common examples found in homes include meats, pet food, cheese, and eggs. Fats and oils, such as cooking oil residue, greasy spills, nuts, and peanut butter, also satisfy their need for fats.

Beyond solid and greasy foods, water is an important attractant for ants, especially during dry periods. Leaky pipes, condensation around windows, pet water bowls, or even a dripping faucet can provide the moisture ants need to survive. These diverse nutritional requirements make most household food items targets for ants.

Why Ants Enter Homes

Ants primarily enter homes in search of food, water, and shelter. Individual ants act as scouts, venturing out to locate resources. Once a scout discovers a food source, it lays down a chemical pheromone trail, guiding other ants from the colony directly to the food source. Even tiny crumbs or spills can be enough to signal a feast.

Environmental factors frequently drive ants indoors. During periods of extreme weather, such as drought, heavy rain, or intense heat or cold, outdoor food sources may become scarce or inaccessible. Homes offer a stable environment with consistent temperatures and protection from predators, making them an attractive place.

While food and water are primary motivators, homes also provide suitable nesting sites. Ants can establish colonies in wall voids, under appliances, or behind window frames, seeking protected spaces to raise their young. This combination of available resources and secure harborage makes indoor spaces appealing to ant colonies.

Limiting Indoor Food Sources for Ants

Managing indoor food sources is an important strategy to deter ants from entering homes. Storing food in airtight containers prevents ants from accessing dry goods like grains, cereals, and snacks. This also applies to pet food, which should be kept in sealed containers.

Maintaining cleanliness in food areas is also important. Regularly sweeping and vacuuming floors removes crumbs and food particles that attract ants. Wiping down countertops, tables, and other surfaces immediately after use eliminates food residues and sticky spills that attract ants.

Proper trash management significantly reduces ant attraction. Using sealed trash cans and emptying them frequently prevents odors and access to food scraps. Washing out recycling bins that may contain food remnants helps. Addressing water sources, such as fixing leaky faucets and drying damp areas, removes another attraction for ants.
