Moths

Learn More About the Moths and Caterpillars of Salt Lake City

Moths are a diverse and widespread group of insects, closely related to butterflies, with tens of thousands of species found across the globe. Typically, they can be identified by their scaly, winged bodies and a tendency to be more active at night, which is why we often notice them fluttering around lights. 

In terms of appearance, moth colors can range from subdued browns and greys to vibrant patterns with startling eyespots designed to deter predators. A noteworthy feature is their feathery or threadlike antennae, which they use to sense chemical cues in the air, especially when searching for mates or food.

Some moth species are considered pests in residential and commercial settings due to their larvae's diet of fabrics, food grains, and other stored products. Moths generally prefer dark, undisturbed areas where they can lay their eggs peacefully and where their larvae can feed without interruption. While moths usually do not pose a health risk, their presence can be a nuisance and lead to costly damage to materials and food sources.

Types of Moths to Watch Out For

Most moths are harmless and essential parts of our ecosystem. However, in the Salt Lake City area and throughout Utah, residents should be on the lookout for specific types of moths that could be considered pests. These moths can range from mere annoyances to the culprits behind notable damage to clothes and food items. 

Utah is home to multiple moth species, including: 

• Clothes moths (tineola bisselliella): Often found in closets and drawers, their larvae feast on natural fibers like wool, fur, silk, and feathers, leading to ruined clothing and textiles.
• Pantry moths (podia interpunctella): Known to infest food storage areas, their appetite includes grains, nuts, flours, and a variety of dried food products, and their feeding habits can lead to contamination and waste.
• Indian meal moths: Recognizable by their distinctive wing pattern—tan on the front half and coppery on the back—they also raid pantry items and are a common sight in kitchens.
• Cabbage moths (mamestra brassicae): While they prefer gardens to houses, these moths can become an issue for those growing vegetables as their larva—cabbage worms—target plants like broccoli and kale.

These varieties are more than an inconvenience; they can cause significant damage and loss. Knowing what to look for helps in early identification and prevention. If you spot signs of these or other moth infestations, Pest Pro Pest Control has the expertise to help you manage and eliminate these pesky intruders from your home or business.

About Moth Caterpillars

Caterpillars are the larval stage of moths and are voracious feeders, with some species having the ability to significantly impact agriculture by feasting on crops, while others might only nibble on leaves, causing minimal damage. Moth caterpillars are as diverse and interesting as their adult counterparts, possessing a range of habits and features that make them truly unique. You can identify these critters by their soft, segmented bodies – often adorned with bristles or spines, and in some cases, striking patterns or colors that warn predators of their potential toxicity. 

These little larvae lead fascinating lives tucked away in their chosen habitats—some roll leaves into shelters, while others create silk cocoons for protection during metamorphosis. As they grow, they molt multiple times, and with each stage, they may change in color and size. 

While most caterpillars are harmless, a few carry urticating hairs that can cause skin irritations, making it wise to admire them from a distance unless you're sure they're safe to handle. Keep an eye out for signs of infestation, such as silk trails or chewed leaves.
