"..I remember seeing those red wasps but never got stung..."
Are you referring to Red Velvet Ants? They are called ants but
actually a wasp. The females are wingless and can be up to an
inch long. Males have wings but no stinger.

I have seen them a few times here in Southern NJ.
I found this thread when looking for information on how everyone
deals with wasps and hornets building nests in their equipment.
It seems every piece of equipment I have has at one time or another
had a nest in it. My scraper blade, the box blade, land plane, and rake
all have nice sized pieces of tube steel with vent holes which make perfect
entrances to a nest built inside the tube steel. Up to now my approach for
dealing with this has been to use some wasp spray and spray in through any
openings I can find on a piece of equipment to kill any current infestations
and to discourage any future nest building by souring the area with the chemical.
Up until now I have been fairly lucky as far as getting stung when working out
behind my in-laws property which is where all my equipment is. But at home the
buggers have built multiple nests in the shrubs around the house and every time
I have to trim I fight with them. Been stung more than once and its no fun. I am
ready to rip those yews out and plant something else.
Are there any other steps I can take? Is sealing off all those openings in the
equipment an option or will it let moisture accumulate and rot out the steel.
