Gaeolaelaps gillespiei is a soil-dwelling mite native to Canada, discovered 30 years ago by Dave Gillespie of Agriculture Canada. While still not well known, it has proven very effective at controlling soil-dwelling Diptera. It consumes over 50% more fungus gnats than Stratiolaelaps scimitus (Hypoaspis miles). It is also able to control thrips on the ground.
Gaeolaelaps is a surface-dwelling mite unlike Stratiolaelaps scimitus, which works at a greater depth. It can be used on coconut fibre substrates and rock wool. Adults are light brown and less than 1 mm long, very similar to Stratiolaelaps scimitus. They move quickly at the surface of the soil. Gaeolaelaps gillespiei feeds on several species of pest insects, mites and invertebrates. Ideal for an in-depth “cleaning” of the soil before starting the season.
