If your attempts to use household remedies for pest control have all come out futile, this mouse mythbusters series is a great way to finally know which DIY rodent repellents will actually reap the right results for you. 

In our last “how to repel mice and rats using household products” series update, we tested out Carolina Reapers, Szechuan Pepper, and Capsaicin Crystals to see which methods were effective in keeping rodents away.

This week, we’ll take a more obscure approach, venturing into the likes of fox urine, Irish soap, and LED rope lights to discover the next best do-it-yourself mice and rat repellent. 

Does Fox And Wolf Urine Repel Rodents? 

Foxes and wolves are very high up on the animal food chain, wolves typically hunting larger prey while foxes opt for smaller prey such as mice and rats. The purpose of putting fox and/or wolves urine on an outdoor area is to trick surrounding pests into thinking they are in predator’s territory. The urine is meant to scare the pests away by triggering their fight or flight response, urging them to flee the area before they get hunted and captured. 

Now, this all sounds great in theory, but Youtuber Ryan Woods put this hypothesis to the test to see how effective it actually is in person. 

Using store bought fox and wolf urine, which was seemingly mixed with skunk spray essence to enhance the smell, Woods created a mound of sunflower seeds on a tray of wood and then surrounded the food with a barrier of urine. He then placed the tray on the floor of his barn (where mice and rats prevalently come to explore in the nighttime), and set up a spy cam to record their reactions. In the video surveillance, we can see rats and mice alike sniffing the air before approaching the tray, walking right over the barrier of urine without hesitation to get to the food provided. The rodents then stayed in that area and ate all of the sunflower seeds until there was nothing left, various other rodents coming in and out to join them in the feast. 

By the end of the experiment it was obvious that Woods had come up short yet again, nothing to show for his efforts but empty sunflower seed shells to clean and the lingering smell of urine in his barn. 

It can be concluded that despite the smell of predator markings in an area, rodents will still venture inwards and take the risk of death as long as edible food is present. Moreover, using these water soluble, urine products certainly do not seem worth the hassle long term, with the requirement of applying every 10 days to even be supposedly effective. Using wolf and fox urine to repel mice and rats from an area is definitely not a viable solution.

Does Irish Spring Soap Repel Rodents? 

Rodents like rats and mice have a keen, sensitive sense of smell, and soaps like Irish Spring are notoriously known for their extremely strong scent. Irish Spring is made as a two in one soap and deodorant, so its composition is filled with all sorts of fragrance. It has been claimed that Irish Soap can be used as a rodent repellent because of its strong odor, meant to repulse the animals with its pungency. 

Youtuber Ryan Woods tested out this theory, purchasing his own bar of Irish Springs and placing it out in his rodent infested barn. Observing via spycam, the mice and rats came up to inspect the new bar of soap all throughout the night. 

It appeared that the mice were indifferent about the soap’s oncoming presence, simply investigating to see if the soap was something edible and then hanging around to eat leftover scraps in the local area. They made no effort to leave the area that the soap was in and acted as if the smell had no effect on them. Their behaviors and the places of the barn they walked around in stayed the same is it would be normally. 

The final straw to prove that Irish Spring Soap does not repel rodents was a mouse using the bar of soap as his own personal chomping block, utilizing its hard texture as a convenient object to chew on. By the end of the experiment, the edges of the soap were indented with teeth marks. If anything, the mice left this experiment with slightly better dental hygiene than they had initially.

Do LED Rope Lights Protect Vehicles From Rodents?

In the RV community, a prevalent struggle is keeping rodents out of the home. Rats and mice love to crawl up into engines and walls, chewing through parts and creating damage to the trailer’s makeup and inner parts. This causes great frustration and expenses, as it is difficult to prevent rodents from crawling into RV’s when they are vulnerably located out in the open. 

It has been widely rumored amongst RV owners that bright lights scare away these unwanted pests, so many people will purchase bright white LED lights and create a circle around their vehicle that they turn on in the nighttime. 

Not only does doing this require a lot of electrical power, but it can also be very disturbing to neighbors residing in the same community. So aside from hearsay about LED lights being able to repel rodents, does using this method actually work? 

Youtuber Ryan Woods simulated his own tiny trailer park inside his barn, using two toy RVs and an 18 foot LED light (made for indoor and outdoor use) to create his own rodent forcefield. Looking in through an overnight spycam, Woods watched and waited with baited breath for how the mice and rats would interact with this new addition to the barn’s decor.  

Throughout the night, the rodents happily pranced through the circle of LED lights, easily crawling over them and inspecting the area for any food. By the next morning, the toy RVs were covered with mouse droppings. Overall, although the test subjects were merely toy trailers, it is safe to say that LED lights do not repel mice, rats, or other rodents from entering an area. It is once again just another rodent repellent myth that does not work.
