Data Analysis & Contour Mapping

Graphs and contour maps bring data to life. For example, the graph bshows cockroach activity at a large food processing facility where we undertake a periodic intensive monitoring programme.

Pest Monitoring Data Analysis

The black plot line shows the proportion of the monitors that have caught cockroaches (a measure of their distribution), whilst the red line shows the numbers caught (a measure of the degree of infestation). What was an extremely heavy infestation in 2008 has been reduced to a much lower level now (eradication is probably impossible at this site). The ‘blip' in late 2011 was caused by poor performance from the incumbent pest control contractor, and resulted in them being replaced.
