Maggot of a muscoid fly

7069.           August 23, about 1/2 inch in size. Found about 20 of these on our floor in the house this morning wondering if they are maggots or something else. Started searching for where they would be coming from and cannot find anything anywhere in the house Pulled fridge and stove out moved furniture around but cannot find any source to where they would be coming from, I am stumped. Renfrew, Ontario Canada

Number 7069. This is a maggot of a muscoid fly, so there must be a food source somewhere in the vicinity. When these maggots complete their growth, they crawl away from their food source in search of a safe, dry place to undergo pupation.
