A mysterious red mark can make you wonder about a tick versus spider bite, especially after time outdoors. A spider bite often causes pain, burning, or swelling soon after it happens. A tick bite may go unnoticed because the tick can remain attached without causing immediate discomfort. An attached tick is the clearest clue, but…
A tick compared to a dime can look surprisingly tiny, especially if you see a nymph. An adult deer tick may be about the size of a sesame seed. A larger dog tick can approach the size of an apple seed. A U.S. dime is 0.705 inches across. Most unfed ticks occupy only a small…
Fleas and ticks are not the same. Both are blood-feeding ectoparasites that can affect your pets, including dogs and cats, but they differ in biology, appearance, behavior, health risks, and treatment. Fleas are wingless insects that jump. Ticks are arachnids that crawl, attach to skin, and feed for extended periods. Learning the difference helps you…
A small red bump, itching, red welts, or swelling can make you wonder what looks similar to a tick bite. Many skin marks resemble tick bites, including mosquito, flea, bed bug, chigger, spider, and ant bites. A rash can also result from irritation, an allergic reaction, or infection rather than an insect. You usually cannot…
Lice and ticks both feed on blood and use a host for nourishment, but they differ in appearance, biology, and health risks. Lice usually live in hair or clothing close to the body. Ticks attach to skin after outdoor exposure. To tell a tick from lice, check the legs first: ticks have eight legs as…
If you are noticing more ticks than usual this year, you are not imagining it. CDC surveillance shows that weekly emergency room visits for tick bites are higher than normal in much of the United States. Rates in most regions have reached their highest level for this time of year since 2017. The pattern does…
A tiny, dark, seed-shaped bug on your skin, pet, clothing, or windowsill can cause instant concern. Several household and garden pests resemble ticks, though many are harmless insects or mites that do not feed on blood. Count the legs first, then check for antennae, wings, body shape, and location. Adult ticks have eight legs and…
A tick compared to a hand is extremely small, yet its size changes substantially as it develops and feeds. An unfed larva can resemble a moving grain of sand, a nymph may look like a poppy seed, and an adult can be similar to a sesame seed. After feeding, the tick’s body can swell several…
If you plan hikes, yard work, or camping in Oregon in 2026, treat spring and early summer as your main tick season. Ticks in Oregon stay most active in brushy, grassy, and wooded habitats, with risk changing by elevation, weather, and location. Protect yourself by using repellent, wearing long clothing, performing a careful tick check,…
Ticks and mites are not the same, although both are eight-legged arachnids in the group Acari. Ticks are generally visible, blood-feeding ectoparasites that attach to people and animals. Mites are usually much smaller. Many species live freely in soil, plants, dust, bedding, or on hosts. Ticks are larger, specialized blood-sucking parasites. Mites include thousands of…
