Wasps seem to be nesting in the ivy growing on the exterior of my home—what would you suggest I use to treat? I also have a wood deck 12″ to 18″off ground in rear of home overlooking a swimming pool which seems to be favorite place for wasps.
Wasp in ivy are easy to control. Just treat it with some of the CYPERMETHRIN we have featured in our WASP CONTROL article. This will both kill any nesting there as well as repel new ones from the area.
Open areas are a bit harder to protect. The deck can be treated with the Cypermethrin which should keep them away. But the pool cannot be sprayed. If they are coming around or into the water for gathering water, we recommend setting up one of the WASP REPELLING NESTS to keep them away.
