Only about 3% of the insects in the world affect humans negatively. That means 97% of insects in the world are beneficial! We should try to protect the good insects.

Not All Holes In The Lawn Are Bad

Solitary ground nesting bees and wasps are beneficial insects. These should not be mistaken for yellow jackets, the social bees that nest in the ground. Yellow jackets do often harm people. Solitary bees and wasps rarely even take notice of people.

Solitary bees and wasps are often pollinating insects. These insects are critical to the pollination of many native plants. Some ground nesting wasps are carnivores. The cicada killer wasp is one of these, hunting cicada insects for food.

Ground nesting solitary bees and wasps make nests in landscapes in open areas where grass has thinned. Sometimes they will congregate in large numbers.
