Wormy Maggots

[2418sal]

Please HELP I have loads of wormy maggots on my patio area over 200 yesterday. Does anybody know what they are. I am a bit worried as to where they are coming from.

Could be larva of flies, possibly bluebottle? Would come from decaying food or animal corpse possibly.

Look for nooks and crannies where they might be. Could be from next door, and not yours at all, especially if other place has poor hygiene.

Pour on boiling water to kill, or solution of Jeyes Fluid.

(Maybe keep a couple in a jar to see what they turn into?)

Thanks for your replies, I have kept some in an open topped container they just die. The birds do not even eat them.
