Ladybird Pest Control in Northamptonshire

JG Pest Control are specialists in Harlequin ladybird control and removal. Most ladybirds are harmless, but when they gather indoors in large numbers they become a genuine nuisance. We are customer focused in everything we do, and our experienced, discreet and friendly technicians offer a guaranteed service across Northamptonshire.

Ladybirds are beetles, usually 1 to 10mm long and round in shape, with hard, brightly coloured and patterned fore-wings (elytra) and biting mandibles. The invasive Harlequin species arrived in England around 2004 and has been spreading northward ever since.

Identifying the Harlequin Ladybird

The Harlequin (Harmonia axyridis), also called the Multicoloured Asian ladybird, is widely recognised as one of the most invasive insect species on the planet. Its appearance varies enormously, which makes it hard to separate from native ladybirds.

Look for a high number of spots on the elytra, often between 15 and 21, sometimes in a grid-like pattern, with an overall size of around 7 to 8mm. The wide variety of colour forms shown here is typical of the Harlequin.
