Everything You Need to Know About Ticks

Ticks don't just bite—they pose serious health problems to you and your pets. Learn what ticks look like, where and when to find them, and how to prevent them in your yard.

The trouble with ticks

Ticks are blood-feeding ectoparasites (a fancy way to say they attach to the outside of their hosts) capable of transmitting species-specific pathogens to people, dogs, possibly cats, and other wildlife. And some even specialize!

What do ticks look like?

Most adult ticks and nymphs have eight legs, whereas larvae (the stage that hatches from the egg) only have six. Adults are usually less than 1/8 inch long.

Sunday Tip:

Bed bugs and fleas can be common lookalikes to ticks. Make sure you identify these pests before any treatment occurs.

When are ticks active?

Ticks are active in spring, early summer, and again in the fall. They become active when temperatures reach 40 degrees but will become less active during high heat in peak summer months. Many ticks found in the U.S. can be active all year round if temperatures remain above freezing.

Sunday Tip:

What’s a scutum? It’s just a fancy word for the hard section behind a tick’s head.

  • round-shape with long mouthparts
  • female with white spot, all reddish brown
  • found in lawns, tall grass, and shrubs

  • found in wooded edges, lawns, and closer to homes

Brown Dog Tick (

Brown Dog Tick (Rhipicephalus sanguineus)

Sunday Tip:

While Brown Dog Ticks will bite people, they earned their name because they're attracted to dogs and spread diseases like canine ehrlichiosis and babesiosis.

How to prevent ticks in your yard

At Sunday, we prefer an Integrated Pest Management approach to deter pests in your yard. Natural pest reduction strategies are the first step to reducing pest habitat and hiding places.

For tick prevention: Keep your lawn well-maintained like trimming bushes and tall grass. Check yourself and your pets for ticks after spending time outdoors, too!

For tick control: When the problem is recurring or natural pest prevention isn't enough, Sunday’s Nix Ticks is a cedarwood oil yard-control spray that kills and repels ticks on contact for up to 4 weeks!
