About Miller Moths

Get rid of miller moths with these couple quick tips.

During late May and early June, Miller moths can be seen in Colorado. These moths migrate from eastern Colorado as well as from further east in Kansas and Nebraska. They are scientifically known as Euxoa auxiliaris and are sometimes referred to as pantry moths.

These moths are actually the adult stage of the army cutworm, which spends most of its life cycle as a caterpillar in the soil. As caterpillars, they feed on grasses, plants, and crops. Miller moths are attracted to bright lights and enter homes through open windows or doorways. In other words, Miller Moths avoid daylight.

During the warm summer months, moths migrate to higher elevations in search of flowering plants. Due to their proximity to the mountains, residents of Fort Collins, Loveland, Windsor, and the rest of the Front Range are fortunate to see plenty of these pests. Miller moths are primarily active at night and tend to seek shelter before dawn.

Changes in weather patterns can have a significant impact on the abundance of miller moths. For example, during periods of drought or extreme heat, miller moth populations may decrease due to lack of food sources or unfavorable conditions for reproduction. On the other hand, periods of heavy rain or cooler temperatures can lead to an increase in miller moth populations as these conditions provide more favorable environments for reproduction and growth.

Why is the Miller moth bad this year?

According to experts at Colorado State University, the amount of moisture in the areas where moths live is a crucial factor. When there is higher moisture, there are more spring and early summer blooms, which means moths have more natural sources of food and are less likely to rely on flowering plants in landscaped areas. In years with an abundance of natural food sources, the moth population is more widespread and not confined to urban areas, making them less noticeable.

They tend to be most active at night, and their presence can cause food contamination, damage to fabrics or carpets, and other problems.

The bad news is that this year, 2023, is predicted to be a bad year for the Miller Moths.

How to get rid of Miller Moths

The good news is that there are several ways to eliminate Miller moths.

One of the most effective solutions I have found how to get rid of Miller Moths is using peppermint air fresheners. The strong scent of peppermint helps repel these moths, making them less likely to enter your home in the first place. To use this method effectively, you should hang air fresheners near windows or doors where Miller moths may enter your home.

On our front porch, we have used one of these air fresheners a Citrus Magic Peppermint Air Fresher – and simply placed it under an outdoor sofa we have. We replace it every few weeks to ensure the scent remains strong enough to repel the moths.

The strong scent of peppermint acts as a natural deterrent for Miller moths. Moths have highly sensitive olfactory receptors, and the strong aroma of peppermint confuses and repels them. The scent masks the pheromones emitted by the moths, making it difficult for them to navigate and find suitable breeding grounds in your home.

Other Methods of getting rid of Miller Moths

In addition to using peppermint air fresheners, there are other methods you can try if you’re dealing with a Miller moth infestation.

The easiest is simply to turn off the lights at night.

Also, wiping window tracks with orange or lemon essential oil every couple of weeks is another effective deterrent for keeping them out of your house.

You can also set up traps using DIY or OTC products that attract miller moths so that you can easily remove them from your home once they’ve entered it – but I’m not a huge fan of these.

Finally, you can simply swat or vacuum them as soon as you spot them inside your home – although this method may not be suitable for everyone!

What about miller moth eggs?

Most miller moths are migratory – they lay eggs in one spot and typically travel to another place after they lay eggs (and after the eggs hatch and a miller moth emerges).

Just to remind you, if you forgot basic biology. These bad boys go Egg -> Caterpillars -> Cocoon -> Moth.

The army cutworm is a pest that feeds on grain crops after it emerges and during spring, causing the most damage at this time. Later, in mid-spring, the cutworm pupates and becomes a miller moth. The miller moth flies to higher elevations to feed on nectar and then returns home to lay eggs.

Final thoughts about how to get rid of miller moths

In the end, it’s pretty simple: turn off the lights at night and use a peppermint air freshener, like this one:

However, it’s important to note that the exact duration of the season can vary depending on various factors such as weather conditions and geographical location.

Once you have identified the source of the moths, there are several methods you can use to get rid of them. Swatting and vacuuming up miller moths remain primary means of attack. You can also set up traps by suspending a light bulb over a bucket partially filled with soapy water; the moths will be attracted to the light and fall into the water and die.

In addition to these physical removal methods, there are also some natural repellents that can help keep them away from your home. Oils such as cedarwood, lavender, peppermint, clove, and eucalyptus are known to repel moths. You can spray these oils around your home or purchase products that contain them to create an effective barrier against miller moths entering your home.

First off, what causes moth infestations outside is…moths! I know, I know, shocking stuff here. But seriously, moths are naturally drawn to the great outdoors, so it’s no surprise when they start hanging out around your patio furniture or outdoor lighting.

But it’s not just the moths themselves that cause an infestation – it’s their life cycle. Moths lay their eggs in shady, protected areas, which then hatch into larvae that feed on fabrics, grains, and other organic matter. So, if you leave your outdoor furniture or potted plants outside year-round, you could be creating a nice, cozy environment for moth larvae to thrive.

Now, as for what you can do to prevent or control a moth infestation outside, there are a few things to keep in mind. For starters, try to keep your outdoor space clean and tidy, removing any piles of leaves or plant debris that could provide a home for moth larvae. You may also want to consider using outdoor lighting that’s low on the brightness scale, to avoid attracting moths in the first place.

How long is miller moth season?

Miller moths are an annual phenomenon that typically takes place between late spring and early summer. During this time period, these moths emerge from their overwintering sites, mainly in the plains of eastern Colorado and neighboring states, commencing their migration to higher altitudes. As they move, they populate other areas in America throughout the course of their journey.

The most notable concentration of Miller moths is observed in Colorado and the surrounding states due to the abundance of ideal breeding grounds and habitat for them. Nonetheless, even though their presence is more significant in these areas, they can travel rather long distances during their expedition. The duration of Miller moth season may depend on several factors like geographical location or weather conditions, but its peak activity usually occurs between mid-May and mid-June.

In conclusion, Miller moths are a fascinating species that undertake yearly migrations around certain parts of North America during a specific season usually lasting from late spring to early summer.

Miller moths are generally not considered destructive pests. Unlike some other moth species, Miller moths do not feed on fabric, damage structures, or cause direct harm to humans or pets. However, their presence can still be a nuisance and inconvenience for homeowners during their active season.

Fortunately, miller moths do not reproduce indoors, and they do not cause any structural damage to homes or buildings.
