Aik! Common bugs in Colorado summer gardens and how to get rid of them

Pests in the indoor garden are plentiful this year. We were in the early summer of a hot spring and a hot summer. Areas are in a state of constant drought and we have a climate change. That is a perfect storm for garden pests.

The list of insects we find in our gardens through the front corridor is long. Each person has his or her own hierarchy. Arguments are often based on the damage they do to property in the garden.

Here are some of the highlights of the winter break.

If you live in Colorado in the hottest minutes, you will know about us in many sizes and colors. Drought is worse because they lay more eggs.

Grasshoppers are very frustrating for gardeners. They love leafy vegetables and are very mobile, making control almost impossible if all your neighbors do the same.

At most adult locusts today, controls are limited. People in the online gardening forums are advised to cut in half with gardeners – this is not for the faint of heart. To read more about Colorado Hospital Extension Services by Colorado State University Extension Service.

Although the Japanese beetles entered the United States in 1916, they have increased their influence over the past few decades. They have no natural savior, therefore you He must be the Savior by picking up what they see.

These beetles begin when those fat, ugly, white bushes are dug into lawns and gardens. They come out like metal green beetles – they are almost beautiful if they do not know their destructive potential. They are harming both larvae and adult stages. The larvae eat grass roots, and adults eat everything that is above the ground. They are known as “skeletons” of leaves; That is, eating soft greens around the blood vessels.

To learn more, Denver Post Gardener columnist Betty Cahill made an in-depth story about the horrible beetles in 2020.

Now brush the leaves (cookies and pumpkins) with my leaves and let the little white flies explode. They are the most common juice-flies that love indoor and outdoor plants. Fortunately, outsiders will be frozen in our winter. So if your outdoor plants are suffering from them now, know that they will not last. But an epidemic is a problem if you get into your houseplants that can live all year round.


Thick, thin hornbills are known to elicit reactions. But to the Sphinx Moths (also known as Hummingbird Moths). The most common are tobacco or tomato horns. All species can grow from plants to insects.

But the caterpillars are good pollen, so they create a mess. Caterpillars can be fun for children – OK, anyone – to raise and release. You can check with your local butterfly center to see if they can rehearse. Go to the CSU Extension Service to learn more about our hornworms species in Colorado.

Cabbage butterflies are often gray and mixed with the same cabbage moths with no black spots on the wings. They both enjoy snacking on the same vegetable as the caterpillars. If you see them flying around now, get ready to pick them up like eggs and caterpillars.

Beneficial insects

It invites healthy ecologists. A garden full of prayer mantis, beetles, laser cutters, and killers can do some good work on other pests’ lice and eggs. When eating lice, be sure to learn the difference between bear beetles and larvae larvae. These larvae often lie like pests when they are able to destroy large numbers of lice.

Support host plants for parasitic wasps. They eat nectar, so try yarrow or dill and other beautiful flowers. These are the opposite of predatory wasps, such as yellow jackets. Dependent turbines lay their eggs in certain hosts, such as the Japanese beetle larvae. They do not bite people or disturb bees. When pesticides are sprayed, these beneficial insects often strike. This can aggravate pests rather than cure them.


Pest management is about prevention, maintenance and healthy ecosystems.

There are pesticides for some of these insects. However, I am not an advocate for them. Depending on what is being used and how it is being implemented, useful bugs can be harmed. Soil creatures are damaged. Storage occurs over time. Birds eat beetles. And the cycle continues.

Start planning for next summer. Design your garden for pest control. Distribute pests in your yard, knowing that each yard or growing area is a small ecosystem with its own needs. For example, avoid planting all tomatoes in one area. Use a multicultural approach.
