An anti-insect Trap Cover comprising a Circular Housing with a slide locking is fixed over the base units of Nahni or Gully Traps, flushed with the floor level wherein a Base Cup capable of holding or retaining a portion of drain water having a raised drain water out let thereby forming a water seal around the Inverted Cup assembled with the said base cup within the Circular Housing. The Inverted Cup is consisting peripheral perforations or slits to allow drain water and immersed within the water seal and whereas the excess drain water coming from the floor creates pressure in the water seal and overflows through the raised drain water out let and falls into the said base units embedded within the flooring bed. A water seal all around the cover allows the water to pass through the perforations or slits or other means of the Anti-lnsect Trap Cover and in turn pass through the Nahni or Gully Trap, thereby allowing the drain water to drain through the drain pipes of the drainage or sewerage systems. The design of the above said Cover does not allow any Insects or Cockroaches into the living environment of dwelling or Offices. Hence, the actual problem of Insects is totally solved, making our life more comfortable. These Traps can be made of suitable Plastic or metals or Stainless Steel or alloys there of. The Size, Shape also can be varied. Preferred one being Circular. A circular weak Central portion of the Top cover with perforations or slits around the tapered portion of the Inverted Cup, can be removed to make a central top hole and a tubular adopter is pierced to lock to facilitate drain water pipe or Hose drawn from the wash basin or sink. -_I
