Can Ants Get Through Plastic? Ants, those tiny but determined creatures, can find their way into our homes and various containers. Can ants get through plastic? Plastic containers and packaging materials are commonly used to store food, household items, and other belongings. In this article, we will explore whether ants can breach plastic barriers and analyze the factors that influence their ability to do so. By understanding the nuances of ant behavior and plastic characteristics, you can better manage ant invasions and protect your belongings.

Understanding Ant Behavior

Ants are known for their adaptability and resourcefulness. These social insects live in colonies and work collectively to gather food, care for their young, and build nests. Ants communicate using chemical signals, or pheromones, which guide other colony members to food sources and potential nesting sites. Their ability to detect and exploit even the tiniest openings makes them capable of infiltrating various materials, including plastic.

Can Ants Get Through Plastic?

The answer to whether ants can penetrate plastic is both yes and no, and it depends on several factors:

  • Plastic Thickness: The thickness of the plastic plays a significant role. Thin plastic materials, such as plastic bags, might be more susceptible to ant infiltration due to their flexibility. Thicker and sturdier plastics, like rigid plastic containers, pose more of a challenge for ants.
  • Ant Species: Different ant species have varying abilities to navigate through barriers. Tiny ants might find it easier to pass through small openings, while more giant ants could struggle.
  • Container Sealing: If a plastic container is not tightly sealed, ants may find gaps or openings to enter. Crumbs or residues left on the exterior of a container can also attract ants.
  • Desperation and Determination: Ants are incredibly determined creatures. If they detect a potential food source inside a plastic container, they might use their collective strength to find an entry point, especially if the container is not perfectly sealed.

Factors That Influence Ant Behavior

Several factors influence ants’ ability to breach plastic barriers:

  • Pheromones: If ants have detected a scent of food or potential resources, they will follow the chemical trails left by other ants to find their way.
  • Ant Size: Smaller ant species might find it easier to squeeze through tiny openings in plastic.
  • Plastic Composition: Some plastics are more malleable than others, making it easier for ants to create openings.
  • Container Condition: Containers with cracks, crevices, or loose lids are more susceptible to ant entry.

Preventing Ant Entry Through Plastic

  • To prevent ants from accessing items stored in plastic containers, consider these strategies:
  • Choose Sturdy Plastic Containers: Opt for thicker, sturdier plastic containers with tight-fitting lids to minimize the risk of ant entry.
  • Keep Containers Clean: Wipe down the exterior of containers to remove food residues and crumbs that might attract ants.
  • Seal Containers Properly: Secure plastic containers to prevent ants from finding entry points.
  • Elevate Containers: Place containers on elevated surfaces to reduce the chances of ants accessing them.
  • Store Items in Cool, Dry Areas: Ants are less likely to be attracted to dry areas with less likelihood of finding moisture or food.


Can ants chew through plastic?

While ants cannot chew through thick and hard plastic, they can manipulate or squeeze through tiny openings in thinner plastics.

Are plastic bags safe from ants?

Plastic bags can be vulnerable to ant entry, especially if they are not sealed or contain food residues

Do ants prefer certain types of plastic?

Ant preferences might vary based on their species and environmental conditions. However, ants are opportunistic and will explore any potential sources of food.


While ants’ ability to breach plastic barriers depends on various factors, it’s clear that they can be surprisingly resourceful when finding food or resources. The thickness of the plastic, the ant species, and the condition of the container all influence their chances of entry. To protect your belongings and prevent ant infestations, use sturdy plastic containers with proper sealing, maintain cleanliness, and store items in elevated and dry areas. By being proactive, you can keep ants at bay and maintain the integrity of your stored items.
