Surface treatment products

Requirements according to “BPR” are for example:

  • a laboratory test showing mortality;
  • a simulated-use test showing mortality;
  • a field trial according to the instruction manual.

 

Depending on the product the tests can be applied to any insect.

The following descriptions refer to cockroach control as an example. 

How could a test according to these requirements be performed in particular? Like this!

 

The "Laboratory test":

Cockroaches are exposed to completely treated surfaces. Glass rings (ø 10 cm) ensure that the cockroaches are bound to have contact to the treated surface for a defined period of time.

 

The "Simulated-use test":

In this test method large cockroaches are exposed in a prepared test arena (1m²).

The surface is partly treated. On the untreated surface the cockroach finds shelter, food and water. A metal ring surrounds the test arena. Thus, the cockroach cannot escape from the arena.

 

The "Field test":

Such a test can be carried out, for example, in an apartment with a kitchenette.

At the beginning the cockroach infestation is determined (e.g. with adhesive traps). Then the treatment takes place according to the product instructions. After this treatment the infestation continues to be determined over days and weeks by means of new adhesive traps.

In the hope the applied product shows good effect and no more cockroaches are caught

 

Depending on the test/product claim numerous (different) test parameters have to be considered.

Test insects: required species, stage, number of individuals per replicate etc.

Type of test arena: size, surface materials (porous/non-porous), equipment, layout etc.

Miscellaneous: untreated control, number of replicates, evaluation times etc.

And much, much more.
