Release calculator

Rates published by suppliers are per square metre per release, which is not the number you have to buy. This works the other way round: your area, your pest pressure and the length of the program, out to bottles, cost and a dated schedule you can print and pin up.

Cost is a midpoint of list prices from the suppliers on the beneficial page and excludes shipping, which on small orders often exceeds the insects. Rates assume even crop coverage; spot-treat hot spots at double rate rather than lifting the whole-house figure.
