4 Tips to Prevent Larder Beetles From Infesting Your Home!

By Allison Clayton

Like many other household pests, larder beetles are a considerable nuisance for homeowners. However, larder beetles can be a problem for many commercial businesses, too! Seeking out pantry and food items, larder beetles will invade your kitchen in search of a quick bite. 

Read our article to understand more about these pantry pests and the best methods to keep them out of your home for good!

What are Larder Beetles?

Larder beetles are small insects, typically never growing larger than half an inch. They have dark brown or black shells separated by a long tan stripe that runs along the middle of their bodies. On this tan marking, you can count six small dots.

While larder beetles are a common household pest in American homes, they exist worldwide. According to Texas A&M’s agriculture extension program, larder beetles may have originated from Europe or Asia, along with the hide beetle. 

These pests have a relatively short life cycle, generally living around 60 days. Female larder beetles will hunt for a food source and lay 100 eggs near it. Some beetles can lay even more at one time. 

In less than two weeks, the small larvae hatch and eventually change into adult forms. Larder beetle larvae look strikingly similar to carpet beetle larvae, with their long, thin bodies and wiry hair. 

A Larder Beetle’s Diet

The larder beetles’ name directly correlates to the insects’ dietary choices. Before the adoption of refrigeration to store perishable food, larders housed many dairy and meat products in homes. 

Here, many homeowners struggled with these pesky beetles invading their dried meat and cheese. While we now put these items in our tightly closed fridges, larder beetles will still eat away at the items in our pantry. 

In addition to meat and dairy, larder beetles will consume your bread, cereal, cookies, rice, noodles, and almost anything else in your cupboards. They will even crawl into your pet’s food to steal a snack. 

Larder beetles aren’t picky eaters. Some species prey on other animal byproducts like furs, hides, and feathers. They can nibble on the pages of your favorite book or even fabric items like clothing and furniture. However, carpet beetles are more likely to eat the clothing in your closet. 

Signs to Look Out For

To protect your food and possessions, keep an eye out for these signs of a larder beetle infestation. 

Damage to Food Packaging 

Larder beetles do not solely prey on unsecured food items. These pests can bore into anything contained in paper, cardboard, or plastic coverings. 

Your bread and cereal may seem safe, but the beetles can bite through boxes to find their prize. Check your items for small holes or tears to see if larder beetles or other pests like rodents have chewed into your food.

The Physical Presence of Larder Beetles in Your Food

While this may seem obvious, a good sign that you have a significant problem is an increased presence of insects. When you begin spotting larvae or adult larder beetles burrowing through your food, you have an infestation. 

If you find larder beetles inside fruits, vegetables, or pantry items, it’s time to call a pest exterminator. Adult beetles deposit their eggs around food sources, and there could be more beetles hiding away or waiting to hatch. 

Larder Beetle Prevention Tips

Whether you want to ward off an infestation or cut back on the number of insects in your home, check out our advice to keep these pests out!

Place Food in Tough Containers

Food can’t hold up against pests when left in flimsy coverings. While sheer plastic wrappings and cardboard boxes keep your food contained on the store shelves, you sometimes need a heavy-duty solution for larder beetles. 

Instead of sticking that cereal box in your pantry after returning from the store, place it in a hard plastic or glass container. Choose one that has a screwable or snap-on top to ensure the bugs can’t crawl in through any small openings.

Clean up Crumbs and Spills

It’s easy to miss a stray morsel when preparing lunch and dinner, but larder beetles can easily find it!

To prevent these pests from entering your home and invading your pantry, try to frequently sweep your floors to catch any crumbs or forgotten foods. If you accidentally spill liquids (especially milk), quickly wipe it up.

Close Off Possible Entry Points

If you have any open cracks, crevices, or openings, larder beetles could crawl in and head straight toward your pantry.  

Look around your home’s foundation for small gaps where pests may slip in. For small cracks, you can typically repair these with plaster, stucco, or caulk, but consult a professional for any extensive repairs your home may need.

Throw Away Infested Food

While it’s annoying and costly to throw away your groceries, especially newly purchased items, you shouldn’t keep anything infected with beetles. 

Larder beetles can’t transmit dangerous diseases, so your food won’t become spoiled when they bore inside. However, they are still unsanitary bugs that may feed on decaying matter outdoors. It’s safer to toss any bug-riddled packages. 

Removing this food will also prevent a larger infestation from taking hold. Because larder beetles lay their eggs beside or inside food, more beetles can hatch and continue to reproduce in your pantry if the food is left alone. 

Tossing out the food removes the adult beetles, prevents the larvae from maturing, and eliminates the possibility of a recurring infestation!
