Mite pest control tests

As mites are very small organisms, working with them is difficult and requires extensive experience and technical skills. Figure 1 shows a larval and a female house dust mite. Adult dust mites grow to be only 0.4 mm in length. Figure 2 shows a larva of the chigger mite with a body size of 0.1 mm.

Insect Services applies the following for testing mite control systems:

  • Textiles (carpets / clothing)
    • Control of dust mites
    • Evaluation of knock down efficacy
  • Acaricides
    • Direct spray tests
    • Residual effect tests
  • Mite repellents
    • Evaluation of mite repellent efficacy against chigger mites on humans in accordance with the OPPTS 810.3700 guideline
    • Testing of ultrasonic devices
  • Attractants

Target organisms:

  • Dermatophagoides pteronyssinus (House dust mite)
  • Dermanyssus gallinae (Poultry red mite)
  • Neotrombicula autumnalis (Chigger mite) – only at certain seasons
  • Further species on demand
