To remove multiple hornet nests from a bush, locate the nest entrances, clear an escape path, don protective clothing, spray insecticide into the nest entrances, and monitor them for residual activity. You need insecticide, goggles, tape, boots, gloves, long pants, a hat, mesh netting and long-sleeved shirts.
- Locate the nest entrances
Approach the bush on a sunny day. Without touching the bush, note the locations of the hornet nests and their entrance holes. Hornet nests often have multiple entrances, and it is important to address all of them.
- Clear an escape path
Examine the area around the bush, and choose a path you can use to run away from the hornets if they attack you during extermination. Remove all obstacles from the path.
- Put on protective clothing
Don protective clothing after sunset. Put on safety goggles, several long-sleeved shirts, long pants, gloves and tall boots. Tuck your pants into your boots, and seal the edges with duct tape. Tuck your sleeves into your gloves, and tape them in place. Put on a brimmed hat, drape netting over it, and tape the netting to your chest and shoulders.
- Spray the nests
Approach the bush slowly and quietly. Stand no less than 10 feet away from it, and spray insecticide into the hornet nests. If the nests have multiple entrances, spray all of them. Soak the nests with insecticide, and then quickly leave the area.
- Monitor the results
Monitor the bush for several days. If some hornet activity remains, apply additional insecticide.
