WD-40 will kill wasps. We call them 'Mud Daubers' as they build a nest with mouthfuls of mud and attach to the underside of eaves. Best time to spray the nest is at night when they are all just hanging around. During they day they are aggressive and most are off doing what they do. if you do spray during the day they others will abandon the nest after it is sprayed. I guess they do not like the smell.
WD-40 will kill weeds and grass, at least it browns them up.
While planting trees in northern Manitoba I ran out of bug dope... WD 40 worked better than any I have tried... I'll probably get cancer someday, but it was a good summer.
Wow, you drink the good stuff!Oh and Vodka or Gin for the Coronavirus .
Instead of buying super expensive and hard to get alcohol hand cleaner. $10 for 50ml or your favourite gin or vodka at $50 for 700ml. Get a little bottle to carry and refill and rub on hands as needed, disinfect mouth as you feel inclined. 100% tried and tested safe and will improve mood in the chaos.
I can attest to the fact that it is entirely possible to start a fire, in an old, vacant house full of cobwebs, when using Right Guard to incinerate a spider.WD-40 or any aerosol can, including bug spray is a standard Aussie protection kit for big hairy things that bite or fly and bite.
Just do not start a bush fire or do it inside.
