Kill’em All

How do I Kill Aphids? Aphids are out and destroying trees and shrubs. There are a few ways to kill aphids and prevent them from coming back. If you prefer to go the all natural way to kill aphids, you can purchase ladybugs. Adult ladybugs can eat up to 1000 aphids a day and as larvae, about half as many.

How to Kill Aphids

One of the problems that many people have when they release ladybugs is that they don’t stay put. To get ladybugs to stay around and eat the aphids at our house and not our neighbors, there are a couple of ways to ensure that ladybugs stay in your yard or garden.

Lady Bugs

First, release the ladybugs before sunrise or after dark because they navigate using the sun. The second way is to cool them off in the fridge before releasing them. They are less active then. The third way to keep your ladybugs close is to water the garden or area where you release them. Ladybugs tend to stay better and they will drink the moisture on the leaves.

Chemical Control

If you choose to use chemical insecticides to kill aphids, we recommend both Zamzows Z-One Insect Control to kill the aphids immediately and Zamzows Tree and Shrub Systemic Insecticide for long-term protection.  For an organic solution, Neem Oil is a great option that will kill aphids on contact and also helps with many diseases like powdery mildew and black spot.

Z-One (ready to spray and concentrate) provides an environmentally friendly, contact and residual insect control for up to four weeks. This insecticide kills hundreds of types of insects which destroy lawns, roses, flowers, trees, shrubs, vegetables, fruits, and nuts. Z-One comes in three convenient sizes of bottles: a 16 oz. concentrate, 32 oz. ready to spray, and a 32.oz hose-end spray.


If you want to stop aphids from coming back to feed on your trees and shrubs, as well as provide protection against other boring and sucking insects, use Zamzows Tree and Shrub Systemic Insecticide. This lasts up to 12 months. No spraying is necessary, just mix at the rate of 1 oz. per gallon of water for every inch of diameter of the trunk at chest height. Simply pour at the base of the plant. This systemic insecticide is not an immediate solution to kill aphids because it takes time for the insecticide to work its way throughout the tree. If you want to kill aphids immediately, use Z-One spray. The benefit to this long-term solution is that it will not wash off and lasts 12 months.

Feed Properly

To give trees and shrubs the absolute best opportunity to be healthy and aphid free, also apply Zamzows Thrive. This will provide nutrients as well as needed trace minerals to the plants. Aphids do not suck their food from plants, they rasp it. Meaning they scrape their food from the outer walls of the leaves. Thrive helps build up the outer walls of the plant’s leaves making it harder for the aphids to eat. Like most insects, aphids are opportunists. They are more likely to go to a plant where it is easier to get their food.
