An insect trap (10) and a method for attracting and/or trapping insects (12) are disclosed. The trap (10) has an intake (14) leading into an interior space (20) of the insect trap (10), which intake (14) continues into a suction duct (16) where an air flow (18) provides a negative pressure at the intake (14). Furthermore, the trap (10) has a portion surrounding the suction duct (16) in the vicinity of the intake (14) and enveloping the suction duct (16) such that the suction duct extends into the interior space (20) of the trap (10). The portion is at least partially permeable to outflowing air (24) and forms at least part of an outer wall (22). In addition, a front side (28), adjoining the outer wall (22), is largely impermeable to air and is at least slightly spaced from an outlet (30) of the suction duct (16).

The invention relates to a composition for the production of CO.sub.2, the use of a composition for the production of CO.sub.2 for an insect trap, in particular for an insect trap for attracting blood-sucking insects and arthropods, and a method for the production of CO.sub.2. The composition comprises a component a), a component b), and a component c). Component a) comprises at least a first yeast strain, which has a low tolerance of less than 100 g of alcohol per liter. Component b) comprises at least one second yeast strain, which has a high tolerance of greater than 100 g of alcohol per liter. Component c) comprises at least one nutrient source for the at least one first yeast strain and/or for the at least one second yeast strain, wherein component c) is being formed by a turbo yeast or by a yeast extract.
