How to Use This Calculator

Enter the target pest species and crop type.
Set the field size in acres.
Review the recommended trap density (traps per acre) and total trap count.
Place traps at field edges and interior according to the pattern recommendation.
Check traps weekly and record catch numbers to track pest population trends.

How the result changes with Field size (acres)

Field size (acres): Total field or orchard area to monitor.
Monitoring intensity (1-3): 1=Low (maintenance), 2=Standard, 3=High (detection/outbreak response).
Trap cost ($): Cost of each trap (delta, wing, or bucket style).
Lure cost ($): Cost of each pheromone lure or bait.
Lure life (weeks): Weeks before each lure needs replacement (typically 4-6 weeks).
Monitoring season (weeks): Length of the pest monitoring season in weeks.

Traps needed: Total number of pheromone traps to deploy.
Trap spacing (ft): Distance between traps in a grid pattern.
Lure changes/trap: Number of lure replacements per trap over the season.
Total season cost ($): Combined cost of traps and lures for the monitoring season.
Cost per acre ($): Monitoring cost per acre for the season.
Total trap checks: Total number of trap inspections over the season.
