Glycyphagus domesticus House mite or Furniture mite
On the left is the house mite. The male measures 0.32 - 0.40 mm long, and the female 0.40 - 0.75 mm long.
The eggs take around 5 days to hatch into the typical 6-legged mite larvae. These feed for 2 days, rest for 2 more, then moult.
The next stage feeds for 4 days, rests for 2 , then moults. The next 5 days are active, then 2 resting days, then a final moult into adulthood.
If conditions turn nasty some can go into a resting stage, and will not wake up until conditions become more favourable. This prolonged resting period can be as long as 6 months.
These mites are found in food, furniture, and anywhere that is damp and badly ventilated. In these conditions they often feed on fungi.
