Pests in the pantry: how to identify and remove food bugs

Finding pests in the pantry can be a worrying concern for homeowners. These pests often go unnoticed until an infestation has already started, damaging dry goods like flour, cereal, and pet food. Any contamination will make your food unfit for human consumption. Knowing the early signs and taking action can help keep your food protected. If you're dealing with bugs at home, our customised solutions can help.

Common signs of pantry pest infestations

Spotting pests in the pantry at the early stage of an infestation is essential for stopping them before they spread. Below are some of the most common signs to watch for and reasons these pests might appear. Common signs of stored product insects (SPIs) include:

  • damage to stored products, live or dead insects (small beetles and moths), larvae, pupae, or silken webbing on food storage bins on shelves
  • infestation, holes, larvae, or webbing on the outside of packets or bags
  • larvae, pupae, or silken webbing in food harborages in cracks and crevices around shelves or on machinery
  • larvae, pupae, or silken webbing in food spillages
  • larvae, pupae, or silken webbing on beams and window sills
  • Indications of the pests in insect traps or rodent stations

Bugs in flour, pet food, and dry goods

Food bugs in flour, rice, cereal, and pet food are common. They are often small and can go unnoticed at first. Over time, though, signs of a growing infestation become clear. 

Look for damage to packaging, webbing, or clumps in flour or grain. You might also spot adult insects or larvae inside food or on shelves.

Why you might have pantry insects

Open food containers, spilled goods, and warm, humid spaces can invite pantry insects. These pests are also drawn to forgotten packages and poor food rotation.

Even clean homes can get stored product insects if the food was already infested before purchase.

Types of pantry bugs and insects

Many different pantry pests may show up in your stored food. Below are some of the most common types of pantry pests found in U.S. homes. Click through to discover more information about each type of pest.

Pantry moth control and traps

Pantry moth control starts with finding and removing the source of the infestation. These pests are often Indian meal moths (Plodia interpunctella), the most common pantry moth species found in U.S. homes.

Indian meal moths are attracted to dry, stored foods. This includes grains, rice, flour, cereal, dried fruit, powdered milk, pasta, seeds, nuts, pet food, and even chocolate. Infestations often begin when already-infested items are brought home from the store. Once inside, they can spread quickly through your cupboards.

Pheromone traps are a helpful tool to control these pests. These sticky traps use a scent that mimics the female moth’s natural pheromones. Male moths are drawn to the trap and become stuck, which helps reduce breeding. While pantry moth traps can help monitor and reduce activity, they won’t target larvae or eggs, so they’re not a complete solution on their own.

 How to get rid of pantry pests at home

Pests in the pantry can be difficult to remove yourself, as they’re small and large numbers can easily infest pantries. Ehrlich technicians have the tools and techniques to do so with minimal disruption.

To control pantry moths, start by checking every package in your pantry. Throw away any items that show signs of moth activity, like webbing, larvae, or tiny holes in packaging. Clean all surfaces thoroughly to remove spilled food and crumbs that can attract moths.

The key to breaking the life cycle is proper cleaning, throwing away infested food, and storing dry goods in airtight containers. DIY efforts may reduce moth numbers, but for lasting protection and peace of mind, our technicians can help identify the source and provide tailored treatment options.

Safe treatments for pantry pests

Ehrlich uses safe, non-toxic methods for treating pantry pests in homes. This may include vacuuming, targeted use of traps, and monitoring for new activity. We’ll also recommend exclusion techniques to help ensure these pests are prevented in the future. We never apply chemicals directly to food.

Preventing pantry pest infestations

Stopping pantry pests before they spread is easier than dealing with a full infestation. The following tips can help keep your food store protected. Preventing pests in stored food starts with good habits and the right storage setup. This means:

  • Keeping food storage areas dry and well-ventilated
  • Storing goods off the floor and away from walls to allow proper cleaning and inspection
  • Using airtight, pest-resistant packaging
  • Cleaning up spills, dust, and leftover food materials in cabinets and shelves
  • Installing and maintaining screens on doors and windows to keep pests out
  • Managing waste properly by sealing bins

In commercial settings, temperature and humidity control can also help. Facilities should aim to store dried foods at temperatures between 50°F and 70°F and maintain relative humidity at 30% or less.

Pantry pest FAQs

Pantry pests don’t usually harm people, but they can contaminate food. This makes it unsafe to eat and leads to waste.

Yes. If food is infested, it should be thrown out to avoid spreading pests. Eating infested food may pose a health risk, and keeping it can lead to a larger infestation in nearby products.

Common pests include Indian meal moths, warehouse beetles, and a range of beetles such as the rust-red flour beetle, confused flour beetle, sawtoothed grain beetle, and merchant grain beetle. These pests target dry goods and lay eggs inside packaging, where their larvae feed on the product.

Store food properly in sealed containers, clean shelves regularly, and check items for signs of pests. Avoid keeping expired or open goods in your pantry.
