A crop duster is flying directly over my house while spraying. I can see the mist coming out while I am standing in the middle of my yard (6 acres). Is this legal?


No. 14 CFR 137.37 - Manner of dispensing is pretty clear:

No persons may dispense, or cause to be dispensed, from an aircraft, any material or substance in a manner that creates a hazard to persons or property on the surface.

Flying directly over you or your house while spraying is illegal. There are factors like altitude etc, but spraying pesticides over people is rarely legal.

    $\begingroup$ @Jonathan Crop dusting usually means spraying pesticides. I've assumed that's what the OP means. $\endgroup$

    $\begingroup$ Aerial application can involve many various products, some harmful, some harmless. Some products are completely harmless ("glue" for rapeseed pods), and some merely do not pose a danger in a specific concentration with a specific distribution method. The suggestion that any and all aerial application near or over people is hazardous and illegal is misinformed and perpetuates popular myths that are harmful to the aviation industry. $\endgroup$
