| − | Trombicula autumnalis are [[Non-Burrowing Mites|surface mites]]. They cause [[Trombiculidiasis|parasitic skin infestation]] and will parasitise any animal, including humans as they are non-species specific. The mite numbers are highest in late summer in temperate climates and are therefore constant all year in tropical regions.

| − | ==Identification==
| |
| − | | |
| − | The mites are bright orange in colour and hairy. They have six legs and no spiracles. They breath through their cuticle
| |
| − | | |
| − | ==Lifecycle==
| |
| − | | |
| − | The lifecycle of Trombicula autumnalis mites lasts around 50 to 70 days. The nymphal and adult stages are free-living in the soil. The female mites become more active in the spring and lay their eggs onto the vegetation. Only the larval stage is parasitic to the host.
| |
| − | | |
| − | ==Pathogenesis==
| |
| − | | |
| − | The larvae insert their mouthparts into the host's skin and inject cytolytic enzymes. They then feed on partly digested host tissue causing irritation and potentially a hypersensitivity reaction.
| |
| − | The Mites are mainly found on the head, ears and flanks of pets and can be found on the face and limbs of grazing animals, depending upon the host height.
| |
| − | | |
| − | ==Control==
| |
| − | | |
| − | Trombicula autumnalis mites are very difficult to control. The main method of control is to try to restrict the access of animals to 'hot-spot' areas.

| − | ==Treatment==
| |
| − | | |
| − | Apply Fipronil spray to affected areas.
