Beggar's Lice is a weed that grows about eight inches tall. It has a purple flower and three leaves. If you have Beggar's Lice in your yard, you may want to kill it. That is because Beggar's Lice has many seedpods that contain tiny hairs. The hairs stick to your shoes and clothing every time you walk by them. They also stick to your cat's or dog's fur.

Step 1

Dig out your Beggar's Lice if you only have a small patch of it. You can use a weeding fork for this. Make sure you get the entire plant, or it will grow back.

Step 2

Purchase an herbicide for broadleaf weeds. You will want to get a liquid herbicide, because Beggar's Lice needs to absorb the herbicide through its leaves rather than its root.

Step 3

Keep an eye on the forecast. You need two things to be in alignment before you using the herbicide on your Beggar's Lice: The temperature must be between 65 and 80 F, and there must be no rain in sight for at least two days.

Step 4

Follow the directions on the herbicide package. If you have a concentrate, you may need to mix it with water first. Some herbicides simply require you to attach a sprayer to the top of the container. If this is the case, the sprayer attachment will be sold along with the product.

Step 5

Spray the leaves of your Beggar's Lice. Be generous, but make sure you are not spraying any other plants in your yard. The herbicide could kill them as well.

Step 6

Repeat one month later to catch any Beggar's Lice that did not die the first time.
