She said fleas will often take up residence in your home.
"They hide in bedding, upholstery, in carpet, rugs," Cornett said. "Things like that are where they like to be. They like warm bedding."
Fleas are often visible as little black dots on your pet and on bedding and furniture. They don't live on hard surfaces.
So what should pet owners do if they discover their pet has fleas? First, treat your pet with something like a flea bath to initially remove them.
Then, treat your pet to stop the cycle of spreading fleas with medication.
"People spend a lot of money in over the counter products that don't work," Cornett said. "And it is a little more expensive to come to your veterinarian, but we have oral meds that actually kill the fleas within 30 minutes.
Fleas can lay thousands of eggs and live about three months. So chances are, they can hatch and you'll need to be prepared to treat everything again. That's why the medication helps stop the spread of fleas, because it stops them from laying eggs, Cornett said.
If your pet is itching because of fleas, they can take Benadryl to temporarily stop itching, she said. Make sure to check with your vet about dosage per your pet's weight, she said.
