What Are Fleas?
Fleas are small insects. They live on animals like dogs, cats, and sometimes people. Fleas bite and suck blood. This causes itching and irritation.
Fleas are hard to see because they are very small and fast. But their bites leave red spots on skin.
Fleas lay eggs on pets. The eggs fall off into carpets, bedding, and floors. Eggs then turn into larvae, then pupae, and finally adult fleas.
How Do Fleas Survive?
Fleas need a warm place and food to live. Your pet’s body is a perfect home. Fleas feed on blood to grow and lay eggs.
Flea eggs are tiny and hard to spot. They hide in places like your carpet or pet bed.
What Is Dawn Soap?
Dawn is a liquid soap. It is mostly used to clean dishes. It can cut through grease and dirt easily.
People also use Dawn for cleaning oily animals after oil spills. This shows it can clean well and remove oils from skin and hair.
Does Dawn Soap Kill Fleas?
The answer is yes, but with some limits.
Dawn soap can kill adult fleas. It works by breaking the flea’s outer shell. This shell protects the flea from water.
When you bathe your pet with Dawn, the soap stops fleas from holding on. Fleas drown or die from the soap.
But Dawn soap may not kill all fleas instantly. You have to wash your pet carefully. Make sure to get the soap all over the fur.
Also, Dawn does not kill flea eggs well. Eggs have a hard shell and are harder to kill with soap.
