What can you do about an in ground bee hive?

Answer 1

Go out to the nest in the evening when all the wasps (ground-nesting "bees" are really various species of wasps) are in the nest, and the cooler temperatures make the wasps less active. Flood the nest with a garden hose and then quickly fill the entrance with mud and dirt to seal the insects inside.

Use a mixture of Sevin-XLR+ and canola or vegetable oil. The oil will act as an attractant and anti-evaporative. ... Malathion is non-selective but if you are not treating a large area, the collateral damage will be small Several "garden variety" insecticides are available.

On a HOT day, Mix 8 ounces of commercial wasp and hornet spray (chlorpyrifos and etc.) into a gallon of turpentine and spray it on the ground in the area with a pump-up sprayer. Remember, almost every chemical can be hazardous to someones health. This is a tried recipe.... not a recommended one. Use good judgment and read the labels. The label is the law.

Organic control is for the birds.
