Thrips: Understanding the Pest

This week we’re taking a look at the commonly called Thunder Fly. These tiny insects are actually called Thrips and are black in colour and narrow with hairy wings measuring around 1.5mm.

Thrips are largely an agricultural pest which is why Herefordshire residents often report problems with Thunder Flies as our rural county has vast amounts of fields and agricultural properties.

So how do these insects cause problems in residential properties and business premises?

Well, they have been known to collect in significant numbers inside smoke detectors and this can trigger fire alarms to go off.

Thrips feed on plant sap and on hot and humid days they congregate on window sills in large numbers.

With climatic changes, these insects become more of a problem and can get into clothing and hair. This is largely a nuisance pest however and a small thrip infestation can normally be dealt with easily by the householder simply removing them from the property.

However, a significant infestation of thunder flies would better be solved by a professional pest controller who has access to professional treatments to solve pest problems.
