Dark wood cockroach

Dark wood cockroach

Ischnoptera deropeltiformis

A species of Ischnoptera, Also known as Sexy legs cockroach

The dark wood cockroach (Ischnoptera deropeltiformis) is called so due to its love for hiding near wood and the dark color of its abdomen. There are some who would call this the Sexy Legs Cockroach, but we would have to agree to disagree on that. Their legs can also be identified by being spiny and anywhere from a bright red to brown.

Are Dark wood cockroach harmful to humans?

Cockroaches can carry some diseases. When they are feeding, they tend to ruminate some food from their stomach, leaving a small amount of food from the previous meal in order to eat more fresh food. They also defecate while moving and eating. These behaviors enable cockroaches to spread a variety of diseases easily, such as Mycobacterium leprae, Salmonella enterica, Yersinia pestis, Staphylococcaceae sp., Escherichia coli, Enterobacteriaceae sp..
Might cause allergies. They carry a lot of allergens, and nearly half of asthmatics are allergic to the proteins in cockroach's saliva, eggs, feces, and exfoliated epidermis.
Bites and other injuries. Although they usually don't attack humans, medical entomologists have proved that they can feed on human nails, eyelashes, hair, skin debris and even calluses. They can also feed on the food residues on the face. So, people in sleep are at risk of getting bitten by cockroaches. In fact, there are medical records of cockroaches crawling into ears.

Where do Dark wood cockroach come from?

Active entry. When the climate starts getting cooler as it approaches autumn and winter, the outdoor food sources are decreased. Cockroaches, which used to be active in neighbors' houses, garbage collection stations, sewers or yards, begin to search for warmer places to enter the houses through cracks.
Passive entry. Cockroaches might have been hidden in old appliances, furniture, suitcases, and other items. Without careful inspections, it is easy to bring in other items as well as cockroaches into the home.

What is the most effective prevention against Dark wood cockroach?

  • Close the doors and windows behind you to avoid cockroaches from entering the house.
  • Regularly check whether the screen curtain of doors and windows has holes or whether the sealing degree of side seam is enough to block cockroaches. Repair and replace them immediately.
  • Check whether the drain on the floor of the kitchen and toilet is well covered.
  • Avoid direct exposure to stored food at home. It should be sealed with plastic bags or put into the refrigerator.
  • If there is any food residue spilled on the ground, carpet, dining table, kitchen board and cupboard, it should be cleaned in time.
  • Install mosquito nets in houses where cockroaches are present.
  • Highly recommended to equip the stroller with mosquito net mesh.
