What do fleas look like? Are they visible to the human eye?
Fleas are small, flat, oval-shaped insects with hard shells covered in hairs. They are dark or reddish-brown in color and measure around 2-4mm (or around one-tenth of an inch). It may be hard to see them, especially if your pet’s hair is a similar color.
They are visible to the human eye, but a magnifying glass can be used if you need to take a closer look. These creatures have six legs: four short ones and two longer ones that they use to jump from place to place as they are wingless and cannot fly.
What do fleas and flea eggs look like on pets?
When checking your pet for fleas you should look out for adult fleas, flea dust, eggs, or larvae. Adult fleas are small brown insects that can be found crawling through your pet’s fur or attached to their skin. If you can’t see the insect itself, you may spot flea dust or flea feces, which looks like grains of blackish-red pepper.
Flea eggs are tiny, oval, white specks (around 0.4mm), which could be mistaken for dandruff or salt grains and flea larvae resemble tiny white worms. Both of these are difficult to see with the eye so it is more likely that you’ll spot the insects or flea dust on your pet.
What are the signs of fleas on your pet? How do you tell if it is a flea?
If you’re wondering whether your pet has fleas, there are a few things you can look out for. Has your pet been scratching themselves, have they lost any fur, or do they have any bites? Have they got pale gums?
Fleas are blood-suckers so pale gums are a sign of anemia from the loss of blood. Fleas usually bite pets on their head, neck, back, or belly and these bites look like small raised red or pink bumps surrounded by a faint red ring. Your pet may also have redness from where their skin has had an allergic reaction to the flea’s saliva. If the bite is infected, they could also have white pustules.
Where do fleas come from?
Your pet is most likely to get fleas from being outside, although they can originate in the home too. They can either be found living in the environment on long grass or bushes or attached to an animal host, which they feed off before mating. Flea eggs hatch in shady conditions.
Once they are fully grown adults, fleas can jump from one animal to another. Your pet may pick up fleas from a bush or from another animal – this could be another cat or dog, or even a squirrel or raccoon. It’s important to understand how cats get fleas and what places your dog may pick up unwanted critters so you can try to prevent it from happening.
How do you know if your house has fleas?
If you want to know if your house has fleas, the first thing to do is check your pet. Are they showing signs of a flea infestation such as scratching? Do they have bites? If you can’t see any, run a paper towel over their fur and if red streaks of blood show up, it’s a sign of fleas.
You can also check your home. Look closely at your carpets, curtains, and furniture for the tiny jumpers. If they aren't visible to the eye, put on a pair of knee-high white socks and walk around on your carpet for a while, then put your feet up on the furniture. The pesky critters will probably attach themselves to the fibers on your socks.
Can fleas crawl on or bite humans and pets?
Some fleas crawl under human skin, however, these aren't the same type of fleas that your cat has. Fleas do bite humans as they feed on blood, but they don’t tend to live on humans as hosts, as we do not have enough hair for them to attach themselves to. Instead, they prefer to attach themselves to animal fur.
Flea bites on a human will generally be scattered around our legs or feet. They are small red bumps with a faint red ring around them. On our pets, flea bites are raised red or pink spots, again, often surrounded by a faint red ring.
