How To Get Rid Of Larder Beetles


Understanding Larder Beetles
The Basics
Before diving into the methods to get rid of larder beetles, it is crucial to first understand what these pests precisely are. Larder beetles are a common type of stored product pest that primarily infest stored food products, the name 'larder' coming from their propensity to infest stored meats. They are about 1/4 to 1/3 inch long, dark brown or black with a tan-colored band with black spots running across the wings. This tells us that our strategy of dealing with them must be concentrated on food storage areas.
Larder Beetle Life Cycle
To effectively counter a larder beetle infestation, it is insightful to study their life cycle. A larder beetle starts its life cycle as an egg. The female larder beetle lays around 100 to 800 small, white eggs directly into food sources. Within twelve days, these eggs hatch into larvae, the stage where most damage occurs. The larvae then shed their skin several times, growing in each instance. After 16-41 days, depending on conditions, they pupate often migrating before doing so. Finally, after several weeks they metamorphosize into adults, ready to propagate the species. Understanding this life-cycle can help us implement strategies that are not only reactive (dealing with existing beetles) but also proactive (preventing future infestations).
Damage Caused by Larder Beetles
Larder beetles, although small, can cause significant damage if left unattended. Most notably, they infest and ruin stored food products in our homes. This not only leads to wastage of food but also puts our health at risk by exposing us to contaminated food. Their larvae are believed to be even more destructive as they can bore through wooden structures and even some soft metals, causing structural damage. The economic implications are double-edged - loss of property and potential expenses on healthcare.
Preventing Larder Beetle Infestations
Cleanliness is Key
The primary preventive measure against larder beetles, like many pests, is cleanliness. Improperly stored food and messy areas provide a perfect breeding ground for these pests. Ensure that dry foods are stored in airtight containers, regularly monitor their condition, and discard anything past its best-before date. Cleaning the pantry and other food storage areas regularly can go a long way in warding off a larder beetle infestation.
The Role of Temperature
Larder beetles are cold-blooded critters, meaning they thrive in warmer temperatures. Therefore, adjusting your home's temperature can be a effective way to prevent an infestation. Consider storing particularly susceptible foods (like pet foods, dried meats, and cheeses) in the refrigerator or freezer. Even if they infest these foods, they will be unable to reproduce in the cold, nipping the infestation in the bud.
Seal off Entry Points
Larder beetles don't just spontaneously appear - they have to get in somehow. Typically, they gain access through gaps and crevices around doors, windows, and utility lines, or they can be inadvertently dragged in on pets or objects. Regularly checking these entry points and sealing them off is crucial. Using weatherstripping around doors and windows, making good use of screens, and inspecting your pet and any object before bringing them indoors can drastically minimize potential infestations.
Eradicating Existing Larder Beetle Infestations
Chemical Insecticides
Despite our best efforts at prevention, sometimes an infestation does happen. One option is to use chemical insecticides. There are many commercial insecticides on the market effective against larder beetles. They work by killing the beetles upon contact or if ingested. It is crucial to use these products safely and correctly, following the instructions on the label to avoid any harmful effects.
Natural Insecticides
If chemical insecticides are not your preference due to their potentially harmful effects, natural methods can be effective too. Diatomaceous earth, a natural powder made from tiny fossilized aquatic organisms, is non-toxic to humans and pets but lethal to larder beetles. The powder causes the beetles to dehydrate and die. Application involves spreading it around the affected area and waiting for it to do its work.
Professional Pest Control Services
Lastly, if the infestation is severe and all DIY methods have failed, it may be time to call for professional help. Pest control services have access to a wide range of tools and techniques that the average homeowner doesn't. Their expertise can help get rid of the infestation quickly and effectively, saving you time, worry and potentially further damage.
