Bed bugs (Cimex lectularius) are hematophagous insects that thrive in human dwellings because they can hide in tiny crevices, survive long periods without feeding, and reproduce rapidly. Their biology creates specific weaknesses that can be targeted to keep them away.. Date latest changes:
The male bedbug possesses a specialized intromittent structure known as the paragenital organ. This organ is an elongated, sclerotized tube that extends from the posterior abdomen and terminates in a sharp, eversible tip. During copulation, the tip pierces the female’s dorsal integument, delivering sperm directly into the hemocoel.. Date latest changes:

How to determine if a dog has a subcutaneous tick?
Subcutaneous ticks are arachnids that embed their mouthparts beneath the dermal layer of a dog’s skin rather than attaching to the surface. The tick’s hypostome penetrates the epidermis, creating a tunnel that can remain hidden for days or weeks.. Date latest changes:
How do bedbugs navigate and locate a human host?
Carbon dioxide (CO₂) serves as a primary chemical cue that guides bedbugs toward potential hosts.

What should you do if a dog itches but has no fleas?
When a dog exhibits persistent scratching and a flea inspection yields no parasites, consider environmental allergy, also known as atopic dermatitis. This condition results from hypersensitivity to airborne or contact allergens such as pollen, dust mites, mold spores, and certain grasses.. Date latest changes:
Rain alters the environmental conditions that ticks rely on for locating hosts. Moisture reduces the temperature gradient between the tick’s microhabitat and the surrounding air, diminishing the effectiveness of thermoreceptive cues. Saturated substrates increase the risk of desiccation failure, prompting ticks to suspend questing activity until the surface dries.. Date latest changes:
Why do fleas appear in an apartment without pets?
Fleas are small, wing‑less insects belonging to the order Siphonaptera.

What will happen if the tick's head stays in the body?
Ticks attach using a specialized feeding apparatus. The chelicerae cut the host’s skin, while the palps guide the hypostome into the wound. The hypostome, a barbed structure, penetrates several layers of tissue and anchors the tick firmly. Salivary glands release a cement‑like substance that solidifies around the hypostome, reinforcing the attachment and preventing dislodgement.. Date latest changes:

What happens to fleas after cat flea drops are applied?
Active ingredients in feline topical flea treatments act primarily as neurotoxic agents that disrupt essential nervous‑system functions in adult fleas, developing stages, and emerging insects. Fipronil binds to the γ‑aminobutyric acid‑gated chloride channels, preventing inhibitory neurotransmission and causing uncontrolled neuronal firing, which leads to rapid paralysis and death..
