I have hundreds of wasps behind my vinyl siding. I have sprayed with wasp spray. While it kills the ones I can see, by the same night there are more. What can I do to kill the ones behind the vinyl? Is there anything a can spray. There are no nests outside They must be hidden.
Spraying a can of pyrethrum like CB 80 Pyrethrin Aerosol with a crack and crevice straw (tube) will do a very good job. The straw tube is very small and should get behind the vinyl, killing the wasps.
Sprayed a complete saturation directly into the nest to kill out the whole nest.
For the past 3 or 4 months we have found wasps flying around even though it is winter. Some are out of energy and some full of energy. We have no idea where they are coming from. Any suggestions?
Wasps will crawl in the openings under siding and around plumbing, etc.
to over-winter. During periods of warm weather they think it is springtime and
try to leave their winter home. They then accidentally come inside. The only
long- term solution is to seal and caulk openings from the outside. Recommended
products to spray around the entry points during the fall
before the wasps have a chance to over-winter inside would be :
We have these insects that we cannot identify : winged, black in color. They are flying insects that are burrowing perfectly round (about 1cm in diameter) in the ground with the dry dirt around it along the border of the lawn closest to the house and through the cracks in the sidewalk. They disappear at night. Are they carpenter bees ?
These are commonly called Digger Wasp(Cicada Killers). Spread Bifen LP over the area.
