What Should I Record to Improve My Pest Management?

Record keeping is the backbone of a successful IPM programme. Without records, each pest encounter is treated as a new event, and every season you start from scratch. With records, you build a cumulative picture of when pests arrive, which crops are most affected, which interventions worked, and which did not — transforming reactive guesswork into strategic management calibrated to your specific site.

The records do not need to be elaborate. A notebook and a few minutes per week are enough to start building genuinely useful data.

What to Record During Each Garden Walk

For each scouting walk, note the date, the weather conditions, each crop inspected, any pests found and their approximate numbers, any beneficial insects observed (ladybird adults, larvae, lacewing eggs, parasitised aphid mummies), and any damage observed. Even a negative observation — "no pests found on brassicas" — is useful data because it confirms the timing when pressure is absent.

If you have set traps, record the catch count from each trap. Note if you carried out any intervention — spray, physical removal, nematode application — and the product or method used.

Seasonal Patterns

After one season of records, patterns begin to emerge. You will see that aphids typically appear on your broad beans in week three of May, that carrot fly damage appears on August-sown crops but not June-sown ones, or that slug activity in your garden peaks in the two weeks after heavy September rain. These patterns, once known, allow you to deploy preventive controls before the problem arrives rather than reacting once it is established.

Intervention Records

For every spray, biocontrol deployment, or physical intervention, record the date, product and rate used, the target pest, the application area, and the outcome at the next inspection. This tells you whether your chosen product worked, how long it took to take effect, and whether re-application was needed. Over time you will identify which tools consistently deliver results on your site and which need replacement.

End-of-Season Review

At the end of the growing season, spend twenty minutes reviewing your records. Identify the three pests that caused the most damage. For each, ask: was the damage preventable with earlier or different action? Did I spot the problem early enough? Was my chosen intervention effective? This review guides your priorities for next season — whether to change varieties, install barriers before pest flight windows, or adjust your monitoring schedule for specific crops.

Simple Digital Options

A basic spreadsheet with columns for date, crop, pest, count, beneficial insects, and action is all you need digitally. A photo taken on your phone with a date stamp gives you a visual reference for population levels that is often more useful than a written count for comparison across seasons.
