Trap for insects

An insect trap, comprising:

• a housing that comprises a power supply, an electrical circuit board, and an integral three-layer grid;
• the three-layer grid comprising an inner layer, a middle layer and an outer layer attached to the housing;
• wherein an electric is developed in the middle layer of the grid which kills insects that come into contact with it;
• and
• wherein both the outer layer and the inner layer of the grid have larger diameter holes allowing insect passage and the middle layer of the grid has appropriate diameter holes to prevent insect passage;
• wherein the housing is mounted on a first portion of a frame with clamps;
• wherein a second portion of the frame different from the first portion of the frame is covered by a collapsible screen,
• wherein a top side of the collapsible screen is fixed to a bottom of the housing, and remaining sides of the collapsible screen are free, allowing entry or exit of a user through the frame while preventing the passage of the insects through the frame;
• wherein the screen has holes with a smaller diameter than the holes in both the outer layer and the inner layer of the grid, such that the screen guides the insects toward the trap;
• and the insect trap is adjustable to external and internal frames of a building.
