Every time you take your dog or cat outside, you risk your pet coming back inside with fleas. The fleas feed off the pet’s blood, and even one flea can lead to an infestation. The fleas settle into your pet’s bedding and other areas of your house. Before the fleas become a larger problem, kill the pests in your yard. Lime on your lawn will kill the fleas, but for maximum results, combine the lime with another method.
Hydrated lime is a calcium-based substance that has been used for centuries to treat fleas. It is most effective when combined with other ingredients, but can also be used alone. This article will provide an overview of the product and how it works, including the pros and cons of hydrated lime for fleas.
Hydrated Lime For Fleas: What Is It?
Hydrated lime is a natural substance that has been used by humans for hundreds of years as a pesticide and fertilizer. It is made from limestone rock that has been heated in a kiln until it becomes soft enough to be ground into powder. The resulting product contains high levels of calcium carbonate, which makes it ideal for use against fleas because these insects are susceptible to this compound’s toxicity.
Hydrated Lime For Fleas: How It Works
Hydrated lime works by releasing small amounts of carbon dioxide gas as it breaks down within the environment where it was applied. This gas will cause fleas on contact to become dizzy and disoriented, which causes them to fall off their host animals’ fur or feathers before they can bite again (or die).
How Long Does Hydrated Lime Take To Work?
Hydrated lime is a type of lime that absorbs water and then begins to break down. It is used in construction, agriculture, and as a soil conditioner. Hydrated lime has a number of applications in the home, including sealing surfaces, removing rust from metal, and cleaning cooking pots. The chemical reaction that occurs when hydrated lime dissolves into a liquid can take several hours to complete.
After dissolving in water, hydrated lime releases carbon dioxide gas and hydrogen ions. The hydrogen ions start reacting with other molecules in the solution to form salt crystals. It takes about three hours for all of these reactions to complete.
The time it takes for hydrated lime to begin working depends on how much liquid has been added to it and whether or not there is any sunlight present. If you are using hydrated lime outdoors on concrete blocks, it will take longer than if you are using it indoors on tile floors because there is less moisture available outdoors than inside your home where humidity levels are higher due to air conditioning systems running all day long during hot summer months when outdoor temperatures rise above 100 degrees Fahrenheit (38 Celsius) or more during winter months when outdoor temperatures drop below freezing levels (-17 Celsius).
Effectiveness
Hydrated lime is effective at killing fleas because it dehydrates the fleas, which leads to their eventual death. The product is typically used to kill and repel pests on farms and other large tracts of land. It kills not only fleas, but it also kills and repels beetles, squash bugs, and aphids. The lime works by killing both the fleas and the eggs laid by the insects, helping to prevent the recurrence of flea outbreaks.
Warning
Before using hydrated lime on all areas of your yard, test a small area. While it’s effective at killing fleas, it can also damage the grass, flowers, and other plant life in the surrounding area. If you’re concerned about the lime killing your grass, hire a professional to perform a soil test. The test measures the acidity of the soil. If your soil is highly acidic, the lime can make the acid even worse and kill the plant life.
Considerations
Use hydrated lime in combination with bug bombs or foggers, especially if you have problems with fleas inside your house. The foggers contain concentrated levels of chemicals that reach the hidden areas, nooks, and crannies of your house, killing the fleas and the eggs. Depending on the severity of your infestation, you may need to throw away your pet’s bedding. Consider using a flea collar or flea spray on your pet regularly and having your pet dipped for fleas at least once a year.
How To Use Hydrated Lime For Fleas
Hydrated lime is a natural product that’s been used for centuries to get rid of pests. It’s a powdery substance that can be mixed with water and spread around your property to help get rid of fleas. When the lime gets wet, it softens up and forms a barrier that keeps fleas from getting into your home. The barrier also keeps other pests out as well.
Hydrated lime is used for many different things, but it is most commonly used as an insecticide. It is a natural insecticide that can be used in your home or yard to control fleas, flies, and other insects. This article will explain how to use hydrated lime for fleas.
- Mix one part of hydrated lime with two parts of water in a bucket or sprayer.
- Apply the mixture directly on the flea-infested areas of your yard or home such as cracks and crevices where they live or hide. You can also spray this mixture around your property to prevent more fleas from coming into your yard or home.
- Wait at least 24 hours before using the area again so that the mixture has time to dry completely before you come into contact with it again (the longer you wait, the better).
