Your Pet Won&#8217;t Stop Scratching<\/strong><\/h3>    <p>Pets that spend time outdoors are prime targets for fleas. Fleas move fast and can be hard to spot on a furry coat, but behavioral clues give them away.&nbsp;<\/p>    <p>If your dog or cat shows the following signs after being in the yard, fleas are the likely source:<\/p>    <ul class=\"wp-block-list\"> <li>Excessive scratching, biting, or licking, especially around the neck, belly, legs, or base of the tail<\/li>    <li>Hair loss or dry, irritated skin<\/li>    <li>Small red bumps or scabs on the skin<\/li>    <li>Flea dirt is visible in the fur when you part it (more on that in Sign #3)<\/li> <\/ul>    <h3 class=\"wp-block-heading\" id=\"3-3-you-spot-adult-fleas-or-their-dirt-\"><strong>3. You Spot Adult Fleas or Their Dirt<\/strong><\/h3>    <p><strong>What do fleas look like?<\/strong> Adult fleas are about 1\/16 to 1\/8 inch long, roughly the size of a sesame seed. You can see them with the naked eye, though it is not easy.&nbsp;<\/p>    <p>They are dark reddish-brown or black, wingless, and have flat bodies built for gliding through fur. They do not fly, but they jump impressively, up to 13 inches horizontally.<\/p>    <p>In your yard, you might spot fleas jumping in grass, especially in shaded, moist areas. A flashlight or magnifying glass helps. Flea eggs are even harder to spot: tiny off-white ovals, about the size of a grain of salt.<\/p>    <p><strong>What is flea dirt?<\/strong> Flea dirt is flea feces and is often easier to find than the fleas themselves. It looks like tiny black or dark reddish-brown specks, similar to ground pepper. You will often find it on pet fur, pet bedding, or carpeting.&nbsp;<\/p>    <p><strong>How to identify: <\/strong>To confirm it is flea dirt and not regular dirt, place some specks on a damp white paper towel. When it gets wet, flea dirt turns reddish-brown from digested blood, while regular dirt stays dark.<\/p>    <h3 class=\"wp-block-heading\" id=\"4-4-fleas-or-flea-dirt-shows-up-indoors-\"><strong>4.

Once your pet brings them in, they can settle into carpets, rugs, upholstered furniture, and even your bed. Finding any of the following indoors is a strong indicator that your yard is infested:<\/p>    <ul class=\"wp-block-list\"> <li>Jumping specks on light-colored flooring or fabric<\/li>    <li>Flea dirt on pet beds or carpets (use the damp paper towel test from Sign #3)<\/li>    <li>Itchy bites when you wake up, concentrated on the lower legs<\/li> <\/ul>    <p>Use your phone flashlight and get low to the floor to look for movement. Flea larvae are tiny and white, while adult fleas are fast movers. If fleas are inside, they are almost certainly still thriving in your yard, too.<\/p>    <h3 class=\"wp-block-heading\" id=\"5-5-the-white-sock-test-confirms-it-\"><strong>5. The White Sock Test Confirms It<\/strong><\/h3>    <p>The white sock test is the most reliable DIY method for detecting yard fleas.&nbsp;<\/p>    <ol class=\"wp-block-list\"> <li>With full-length pants on, pull on calf- or knee-high white socks.<\/li>    <li>Tuck your pants into your socks. The fleas are forced to jump onto the white fabric instead of your skin.<\/li>    <li>Walk slowly through suspected areas, checking your socks every few minutes for tiny dark specks. If they are moving, they are fleas.<\/li> <\/ol>    <p>The best places to test in your yard include:&nbsp;<\/p>    <ul class=\"wp-block-list\"> <li>Under decks, porches, or dense shrubs<\/li>    <li>Along fence lines<\/li>    <li>Spots where your pet spends the most time<\/li>    <li>Areas with tall or overgrown grass<\/li> <\/ul>    <p>The test works because your body heat and movement attract fleas, which then jump toward you.
