Sadly, not all of our guests are welcome, and some are downright gross! But this does allow an opportunity to educate our clients about ticks and Lyme disease. There are a lot of myths out there, lets discuss some common questions... (We apologize in advance for any nightmares that this post induces).
> These are two adult, female Ixodes Scapularis (Deer tick). These are a tick species that is endemic to our Region, and can carry the bacteria that causes Lyme disease (among others). The ticks in the photos are engorged, which means they have taken a blood meal from a host (in this case, a dog).
> Ticks have four life cycles, eggs - larva - nymph - adult. Once the eggs hatch, the tick will require a blood meal at each of the following life stages.
> Ticks can become infected with blood diseases when they feed on an infected animal such as a rodent. When they molt into the next life cycle and require a blood meal again, these diseases can be passed along to that host.
> Ticks find their hosts by detecting breath and body odors, or by sensing body heat, moisture, and vibrations. They typically pick a place to wait by identifying well-used paths. Then they lay in wait for a host, resting on the tips of grasses, shrubs or leaf litter. Ticks can’t fly or jump, but many tick species wait in a position known as “questing”, which is when they grab hold of vegetation with their back legs, while waving their front legs in the air waiting to grab and climb onto a potential host passing by. Once on a host, ticks often "wander" looking for an ideal place to feed. If they find a sheltered spot, they can go unnoticed for days.
> Ticks DO NOT burrow under the skin. This is likely the most common misconception, and many pets have had lumps and bumps needlessly prodded and squeezed thinking that a tick was under the skin. Ticks insert their mouth parts (circled in the photo) into the skin, sometimes secreting a cement-like compound to help them stay attached. They also can secrete an anesthetic type of chemical in their saliva that allows their bite to go undetected.
> Ticks typically feed for several days, only dropping off the host when they have completed the blood meal and are "full". After this they will either molt into the next life stage, or if adults, they will lay eggs and the cycle will repeat.
Now that we are all sufficiently grossed out, it's time for a shower, a tick check (just to be sure, because now our skin is "crawling") and stay tuned for a follow up post about what to do if and when you find a tick on your pet (or, heaven forbid, on yourself).
