What should you do if you suspect a tick bite?
Ticks vary in geographic range, preferred hosts, and disease potential. Accurate identification of the species encountered after a suspected bite informs the urgency of removal, the need for medical evaluation, and the likelihood of pathogen transmission.. Date latest changes:
What will happen if you remove a tick without its head?
The hypostome is the ventral, barbed organ that a tick uses to embed itself in host tissue. Its denticles interlock with skin fibers, creating a secure attachment that resists the host’s attempts to dislodge the parasite. During blood ingestion, the hypostome serves as the conduit for saliva and anticoagulants, while simultaneously anchoring the mouthparts.. Date latest changes:
How do bedbugs excrete: what you need to know about their secretions?
The foregut of a bedbug constitutes the anterior portion of its digestive tract, extending from the mouthparts to the junction with the midgut.

Why does a dog constantly scratch if there are no fleas?
Dogs may scratch intensely even when fleas are absent; the underlying issue often lies in the condition of their skin. Healthy skin provides a protective barrier, regulates temperature, and prevents entry of pathogens. When this barrier is compromised, irritation triggers the urge to scratch.. Date latest changes:
Bed bugs respire through a network of tracheae that deliver oxygen directly to cells. Air enters the system via paired spiracles located on the lateral margins of the abdomen. Each spiracle opens to a tube that branches into finer tracheal vessels, ending in microscopic tracheoles that diffuse gases across cell membranes.. Date latest changes:
How can you confirm that bed bugs are in your bed?
