Selective detection of bed bugs

A method of detecting a presence of pests comprising:

• reacting an agent with a targeted biochemical analyte secreted by pests to produce an adduct having a molecular weight than the agent alone, and
• determining the presence of pests based on the presence of adduct.
• wherein the agent is:
• or a structure according to formula V
• or a tautomer thereof, wherein
• X is S or O;
• Z3 and Z4 are each independently O or S;
• R7 and R8 are each independently selected from the group consisting of C1-C4 alkylene-O—(C1-C4 alkylene)qR9 and C1-C4 alkylene-S—(C1-C4 alkylene)z R10;
• R9 and R10 are each independently selected from the group consisting of hydrogen, C1-C8 alkyl, C2-C8 alkenyl, C6-C10 aryl, and a polymeric bulking group;
• and
• q and z are each independently an integer from 0 to 10.

A pest control device comprising:

• a sensor including a sensor cell, wherein a surface of a sensor cell is coated with a coating comprising an agent that reacts with a targeted biochemical analyte secreted by pests,
• wherein the agent is:
• or a structure according to formula V
• or a tautomer thereof, wherein
• X is S or O;
• Z3 and Z4 are each independently O or S;
• R7 and R8 are each independently selected from the group consisting of C1-C4 alkylene-O—(C1-C4 alkylene)qR9 and C1-C4 alkylene-S—(C1-C4 alkylene)zR10;
• R9 and R10 are each independently selected from the group consisting of hydrogen, C1-C8 alkyl, C2-C8 alkenyl, C6-C10 aryl, and a polymeric bulking group;
• and
• q and z are each independently an integer from 0 to 10.
