In W rats, retinal cell loss following 1 week of exposure was observed only in the superior retina of rats exposed to blue-LEDs. “After 1 month of exposure, all LEDs induced retinal damage in the superior retina, and only blue and green LEDs induced damage also in the inferior retina.”
While rats are comfortable in the light, they will typically avoid it simply due to their nature. There are also certain types of lights that they may make additional effort to avoid, such as flashing lights. That is why so many companies sell light machines designed to deter rats; they have their basis in fact.
Since rats are so sensitive to light, bright light – sunlight and even intense household lights – can cause eye damage. Rat eyesight is poor – about 20 times worse than our own.
To your pet, LED lights, especially those made with cheap parts, may have a strobe-like effect. Dogs, for example, are more than three times as sensitive to the type of flicker produced by LED lights than humans.
A study in mice shows that the actual color of light matters; blue light keeps mice awake longer while green light puts them to sleep easily. Light affects sleep.
Unfortunately, the light inside your house is not a very effective deterrent to mice. Once inside a house or a building, they can easily look for dark areas to hide until such time as all lights are turned off. Places they can hide include inside the walls, crawl spaces, attics, and ceilings.
The use of strobe lights to deter rodents from entering an attic or crawl space has been proven effective with our customers. Strobing lights are generally considered the safer alternative compared to using toxic pesticides and poisons in your home. The strong strobing effect chases rodents out.
The short answer is no – LED lights are not bad for dogs, but not all LED lights are the same. However, the color of the LED strip lights has different effects on your dog. Dogs are most likely to be kept awake by blue light at night because it mimics daylight and can disrupt their circadian rhythm.
LED Lights have a smaller Carbon Footprint
Greenhouse gas emissions associated with the LED lights are considerably lower than conventional incandescent or Compact fluorescent lights. According to careful calculations, one LED bulb, providing the same luminosity as one incandescent bulb emits 80% less greenhouse gases.
Blue light can also alter the behavioural patterns of animals including bats and moths, as it can change their movements towards or away from light sources.
Peppermint Oil
On a cotton ball use no more than 5 drops of 100% peppermint essential oil. Spread the oil on areas that you want rats to avoid, in your case, around the garden.
Intriguingly, both rods and cones of pigmented as well as albino rats show a retinal response to red light, with a high sensitivity of the dark-adapted retina and large electroretinogram responses in the mesopic range. Our results challenge the misconception of rodents being red-light blind.
As it turns out, there are several smells that these pests cannot stand, which means you can use them to your advantage. But what exactly do mice and rats hate to smell? Mice can be kept away by using the smells of peppermint oil, cinnamon, vinegar, citronella, ammonia, bleach, and mothballs.
Hard materials such as bricks, cinder blocks, and soft forms of concrete aren't a problem for these critters. They can even get through softer metals like aluminum sheeting, lead, copper, iron, and gold.
Rats and mice are nocturnal with most activity taking place between approximately one half hour after sunset to about one half hour before sunrise.
Essential oils are some of the best natural rat repellents. Rats have a highly developed sense of smell, which makes strong odors such as pine oil, cinnamon oil, and even peppermint oil offensive to them. Cayenne pepper, cloves, and a mixture of vinegar and ammonia will keep rats away as well.
Enclosed fixtures that don't allow for proper ventilation can drastically affect the temperature of the LED bulb, causing it to overheat and shortening the lifespan of the bulb. That's why some bulbs will tell you not to use it in an enclosed ceiling fan or fully enclosed porch light fixture.
The positive side of the LED is called the "anode" and is marked by having a longer "lead," or leg. The other, negative side of the LED is called the "cathode." Current flows from the anode to the cathode and never the opposite direction.
Research studies discovered red to be the best color light to help you sleep, because it increases production of melatonin as well as full darkness. On the other end of the spectrum, blue is the worst. Despite being a calm-inducing color on most occasions, blue is not suitable for lighting a bedroom.
Commons reasons to use a pet light include keeping the animal calm, giving them a sense of company, or helping them to see. Some dog owners say that their pets are afraid of the dark. This will only apply to a small number of dogs, but there is an easy way to tell if your dog is afraid of the dark.
LED lights do not attract bugs the way incandescent lights do. But they do help make bug lights more efficient. The LED options are also quieter than traditional bug zappers. If bug zappers aren't an option for you, color lighting is an alternative.
Rats are extremely sensitive to light. Retinal damage due to light exposure has frequently been reported. Albino rats have increased sensitivity to bright light since they lack the normal pigmentation of the eyes.
Rats are naturally most active at night and are very sensitive to light; bright light can cause stress and harm their eyes - particularly albino strains (red-eyed white rats).
This makes peppermint oil, chili powder, citronella, and eucalyptus the most common natural rodent repellents. Chemical smells, such as ammonia, bleach, and mothballs also work as mice deterrents.
