[/font][font=Arial, Helvetica, sans-serif]Place a cloth bag over the entire nest and quickly tie it off at the top; as you draw in the tie, pull the nest free. The bag should be well sealed. Set the bag in a pail of water; drop a rock on the bag to keep it fully submerged. [/font][font=Arial, Helvetica, sans-serif]
Ground nests
[/font][font=Arial, Helvetica, sans-serif]If the entrance to the nest is easy to see, it can be blocked using a large, clear bowl. Use caution as there may be more than one entrance to underground nests. Set the bowl over the nest entrance and work it into the ground a bit so there are no exit routes for the wasps. This will confuse the wasps, but they won't try to dig a new entrance. The bowl should remain in place for several weeks. [/font][font=Arial, Helvetica, sans-serif]
Underground or inside wall nests
[/font][font=Arial, Helvetica, sans-serif]Nests in wall voids or underground are more difficult to remove, and should be left to the professional. (If you detect a wasp nest in the wall, do not try to eradicate it from the outside. This will force them further into the house.)
When hiring a professional to treat wasp problems in the home, ask what methods will be used. A non-toxic alternative to insect sprays and dusts is vacuuming. Some prefessional exterminators are equipped with specially adapted vacuum cleaners to draw out the wasps, which are then sold to pharmaceutical companies who extract the venom for immunotherapy.[/font][/font]
