Seeing cockroaches is something usual, but you have also to look for many signs including:


  • Dead cockroaches
  • Musky, sour odors
  • Check along cracks for brownish stains
  • Coffee-grounds-like droppings along runways
  • Small egg cases that look like leather
  • When the nymphs grow, they shed old skins. So, look for these old skins.



To infest a building, cockroaches need hiding places, access, water, and food. You need a team effort by a pest control operator, tenants, and management to eliminate the cockroaches.



Properly teat all affected units, inspecting neighboring units, and of course, the infested areas during follow-up inspections.



  • Follow the pretreatment instructions of the pest control operator for your place.
  • Update the building manager with any plumbing leaks.
  • Don’t leave a pets’ food or water dish, and dirty dishes out or in the sink overnight.
  • Keep food in completely sealed vessels.
  • Clean up water spills quickly, and even eliminate water sources.


  • Repair all water sources that leak in the kitchen and bathrooms.
  • Seal the exterior doors very well by using door sweeps.
  • Repair all cracks and holes in floors, ceilings, and walls to block hiding places and access.



  • Do not keep insecticides in the reach of pets and kids.
  • Be sure to read the labels of the insecticides, that is considered as a temporary solution, before buying them to choose the right ones for your units.

Contact sprays may last for a few hours when they are sprayed on bath or kitchen surfaces. Some other sprays called residual, which come in several forms, may last for months! These sprays are applied along runways and in crevices and cracks. Another insecticide called dust is used between crevices or cracks and walls. You can only use dust in dry, void spaces under refrigerators, stereos, televisions, stoves, and cabinets.
