Ticks can be very small, which can make them hard to spot and remove before they have a chance to spread diseases. In this Tweet from the CDC, re-posted on the Entomology Today website puts the size of ticks into perspective:
The ticks shown on this muffin are not even the smallest of ticks. These are
nymphal stage ticks, the "teenager" ticks, where as when
ticks first hatch as larvae they are even smaller.
Ixodes scapularis ticks (the ones primarily studied in our lab and one of the species that spreads Lyme disease) can be less than a millimeter in size.
