Wasps for Caterpillar Control


Many people think the paper wasps and mud daubers are a dangerous garden pest that needs to be controlled.  In my view, they are excellent pest controllers, especially for caterpillars.  They catch insects and feed them to their larvae.
These cells will be filled with hungry baby wasps!
I was looking at my hollyhocks, looking for the insect that made web nests like this in leaves and ate the leaves.  Most of the webs were empty, because wasps were systematically locating the nests and eating the caterpillars. The wasps ignored me as they moved from leaf to leaf.

is the probably leaf muncher.  Mallows are one of their main host plants.

Wasps are also patrolling the Four O'Clocks, the tomatoes and the peppers, which have very little caterpillar damage this year.

When would I destroy a wasp nest? Nests in areas where they risk being bumped and bringing the wrath of the inhabitants on me are destroyed when I find them.  The first photo is of a nest that the wasp built in the garden shed, on my weed trimmer.  I destroyed it and hope she found a better place for her next effort.

Natural Pest Control for Gardeners and Landscapers: It's a Bug-eat-Bug World

The no-work, pesticide-free approach to controlling garden pests is to let their natural enemies eat them. The easiest and cheapest way to minimize the numbers of insects that damage your plants is to encourage predator insects that will eat the plant-damaging insects for free. The easiest and cheapest way to encourage these insect predators is to stop killing them - stop using pesticides in the garden. There may be a brief surge in the plant eaters, but the predator populations will expand to control them.

Think of the advantages for you - no buying pesticides, no weekends wasted spraying pesticides, not worries about pesticide residues on your vegetables. Just sit back and watch the food chain in action. For sex, violence and mayhem, it matches anything you can find on television, except maybe Game of Thrones.
