mouthparts and an adhesive (cement) secreted in the saliva. TICKS & MITES / PARASITES LOCATION OF TICKS IN SKIN Ticks feed by creating a wound in the dermis into which blood flows. The ticks attach to skin with barbed mouthparts and an adhesive (cement) secreted in the saliva. dermis tick body palps blood pool cement epidermis capillaries (papillary loops)
