Tiny Green-Grey Worms Crawling on Wall are Either Inchworms or Sawfly Larvae

“I found your website on Google and hope you could help me with the worm in the attached photo”, writes Diane in Japan about the little greenish grey creature pictured below. “It is grey with a black head, no legs. I am located in Aichi, Japan, and this is the second time I found it in my house (last night, first time): one time on the wall, the other on the object near the same wall. Both times were around 8 or 9 pm, when the temperature went down to about 26 degrees Celsius. One of my friends said it looked like those you find in vegetables. But it doesn’t explain why I find it two nights in a row when there’s no uncooked vegetables kept in the open air? they are all in the fridge which is three meters away, by the opposite wall. I am honestly worried about the possibility that there may be more of them in the house, whether it is harmful, and how to get rid of it. I’d really appreciate it if you could help me.”
