What measures can I take to eliminate the tiny black ants that we often encounter in the kitchen and prevent them from returning?

Ants are a common nuisance in Tucson and throughout the United States. The Tucson area hosts a variety of ant species, each with unique control requirements based on factors such as their particular species, colony’s age, location of the invastion, and other factors.
Here are several general steps that are typically effective in preventing most types of ants from entering your house and kitchen.

Ants excel at reproduction, expanding their colonies through various means, including sending swarmers to create new colonies, or through a process known as budding, where a single colony divides into multiple ones. Tucson’s natural environment is conducive to ants’ thriving and reproduction. Certain conditions both inside and outside your house can enable ants to gain entry.

Maintain outdoor cleanliness.

Most ant infestations originate outdoors. Thoroughly examine the exterior of your home for any food waste, especially in and near garbage cans, barbecue grills, patio furniture, and areas where pets are fed. Make sure to clean these areas frequently and properly dispose of trash to prevent ants from being attracted to your home. Additionally, consider using secure containers for garbage and recycling. Also, avoid leaving pet food outside, which can attract ants and other pests. Maintaining a clean outdoor environment and removing potential food sources make your property less appealing to ants, reducing the likelihood of an infestation.

Keep your home’s interior clean.

Ants are known for locating food sources and communicating their findings to their comrades. Ants can be attracted to and sustained by food on countertops, crumbs underneath appliances, and debris in cabinets and corners, often for long periods of time. Regularly clean these areas, wiping down countertops, vacuuming or sweeping floors, and removing food debris from cabinets and storage spaces. Additionally, store food items in airtight containers to reduce the availability of food sources for ants. Maintaining a clean interior and diligently addressing food spills and debris can minimize the chances of ants invading your home.


  1. Avoid “Bridging”: Ants can use trees, plants, and other shrubbery touching or hanging over your house as a “path” to gain entry. Regularly trim plants and various vegetation, keeping them at least six inches away from your home. Ensure that trees are not in contact with power lines or overhang your roofline, as ants can exploit these routes as additional access points. Maintaining adequate clearance between your home and the surrounding vegetation can decrease the likelihood of ants using plants as a bridge to gain entry.
  2. Don’t overwater: Overwatering your plants and lawn can increase moisture levels around your home, creating an ideal environment for ants and other pests to thrive. Ensure your irrigation system functions properly and follow recommended watering guidelines for your plants and lawn type. Properly managing water usage can help prevent ants from being attracted to your home.
  3. Adequately maintain plants susceptible to honeydew-producing insects: Honeydew, a sugary and sticky liquid Secretions produced by aphids, scale insects, and other pests, can attract ants. These insects infest specific trees and plants in the Tucson area, making honeydew an appealing source of food for ants. Regularly inspect your plants for honeydew-producing insects; treat them with appropriate insecticides or horticultural oils if necessary. Addressing these infestations on your property can help prevent ants from entering your home.

Fill or block any noticeable openings and gaps.

To prevent ants from entering your home, it is recommended to seal any visible gaps or openings around your house, including those found near AC lines, water fixtures, and weather-resistant seals located close to doorways. Inspect your home’s foundation, windows, and vents for any gaps or cracks that could allow ants to enter. Additionally, check for any gaps around electrical and plumbing penetrations through your walls, floors, and ceilings. Sealing these potential entry points can significantly reduce the chances of ants invading your home. However, even with thorough sealing, some ants may still find their way inside through undetected or unreachable cracks and openings. Regular monitoring and maintenance can help address these issues as they arise.
