The Arborvitae, also called Thujaplicin, is a coniferous plant with needle-like leaves that grow in clusters. Arborvitae trees must be sprayed with a systemic insecticide regularly to keep them free of pests such as scales and mites. Systemics are commonly used to treat arborvitae trees because they kill insects through ingestion instead of contact. Apply systemic insecticides directly to the soil to keep roots protected. Arborvitae (Thuja) are evergreen trees that are commonly used in landscaping. With proper care, they can live for many years, but they can also be damaged by insects. If you have arborvitae trees, it is important to use a systemic insecticide on them to protect against damaging pests. ArborGreen systemic insecticide is a non-repellent, micro-encapsulated insecticide that helps protect trees from damage caused by caterpillars and other chewing insects.
Systemic insecticide for arborvitae Systemic insecticides work their way into the plant’s vascular system, most often as soil drenches, but sometimes through foliar applications or injection. systemic insecticide for arborvitae Systemic weed killers is seen as a good option for dealing with difficult-to-kill weeds like Canadian thistle and dandelion. The best systemic insecticide for trees is the product I would suggest applying in high dosages with a pump sprayer so that it reaches the critical areas of the tree where there has been infestation.
What kills arborvitae trees While they do not offer real control of the pest, they can temporarily distract it from feeding on the plant and enable you to carry out control by other means simpler methods. Systemic insecticide for arborvitae is a poison that travels through the tree’s veins and attacks its heart. This kills the tree. Usually, systemic insecticide is made of chemicals such as imidacloprid. Arborvitae insecticide can be sprayed onto the tree or injected into the ground. It then makes its way through the roots and stems.
Can I Use Systemic Insecticide on My Arborvitae?
You can use any systemic insecticide for your arborvitae. Systemic products work best when you apply them directly to the soil around a tree or shrub and then water it in well. They are absorbed by plant roots and move up into the plant, providing protection throughout its system (hence, “systemic”).
The best time to apply systemic insecticides is early spring before insects become active because they’re more effective against pests that haven’t yet hatched from overwintering pupae/eggs/cocoons.
Why Is My Arborvitae Turning Brown?
If you have a browning arborvitae plant, there are several possible causes. The first and most likely is spider mites. These tiny pests cause leaves to turn yellow or brown and fall off in large numbers. The best way to determine whether your arborvitae is suffering from spider mites is by examining the undersides of its leaves with a magnifying glass. If you see little pale spots on the underside of the leaf that look like salt crystals, then chances are good that spider mites are at work.
Other possible causes include environmental factors such as nutrient deficiencies or an excess of fertilizer or water; diseases such as Fusarium wilt or Monilinia fructicola (brown rot); insect infestations such as borers; or physical damage caused by animals like squirrels who chew on branches for food and nesting material.
How Do I Know if My Arborvitae Has Been Affected by Spider Mites?
If you’re unsure if your arborvitae is infested with spider mites, here are a few ways to tell:
- Use a magnifying glass. You may be able to see tiny spider mites moving around on the leaf or feeding on the underside of the leaves. Look for webbing and small brownish dots (droppings) that indicate where they’ve been feeding.
- Examine any damaged leaves carefully under bright light; they may appear yellowish or pale green in color, and it’s possible that some of them will turn completely brown/dead over time.
- Look out for stippling, this is when small white dots appear on affected areas of the plant’s body use your magnifying glass if necessary because they’re very small and hard to spot.
When Can I Expect the Spider Mite Damage to Affect the Arborvitae Appearance?
It may take several weeks to several months for spider mites to damage the arborvitae appearance. As a result, the first visible signs of spider mite activity on your arborvitae may not be evident until late summer or early fall.
The good news is that even if you notice early signs of spider mite damage in June, it’s still possible to treat your trees before they suffer significant damage. If you catch and treat your trees early enough (while they are still green), there will likely be no visible damage when you return next spring.
What Are Some Symptoms of a Spider Mite Infestation?
Spider mites are very small, but they can be identified by their webs. Spider mite infestations typically occur in the summer and fall. Other symptoms of a spider mite infestation include:
- Yellowing of leaves
- Twig dieback
- Scaling of bark on lower trunks
Systemic Insecticides Should Be Applied Early.
There are several systemic insecticides available for treating arborvitae. Systemic insecticides work by moving through the plant’s vascular system and killing insects that feed on it, including mites. You should apply these products before mites are visible on your plants, as they will not kill them once they’ve hatched out of eggs.
The systemic insecticide should be applied early in the season so that it can move through the tree before mite populations explode in late summer or fall.
Systemic Pest Control Is Effective and Easy to Use.
Systemic insecticides are the safest, most effective, and easiest-to-use method for controlling sap-feeding insects on your arborvitae. The method of action is systemic; it enters the plant through the roots and moves to all parts of the plant, including leaves, stems, and branches. Systemic insecticides are applied to the soil around trees at planting time or when plants become established in spring. Applications can be made at any time of year but should be timed according to pest activity.
Systemically applied insecticides have no effect until eaten by an insect pest that’s feeding on foliage or boring into the bark – then they kill them right where they’re standing. The systemic insecticide takes several days to move through a tree before reaching its target pests (which is why you should apply them when pests are active).

In conclusion,
Arborvitae is a small, hardy evergreen that can be used as an accent tree or a hedge. Unfortunately, arborvitae is also very susceptible to a variety of insect pests, including the Western conifer seed bug and the twig girdler. These bugs burrow into the trunk of arborvitae and lay their eggs in the tree’s cambium layer, which can lead to serious damage.
To prevent further damage, you should treat your arborvitae with systemic insecticides. Systemic insecticides are slow-acting but will continue to kill insects long after they have stopped being applied. This means that your trees won’t need continual applications of these chemicals, which can save time and money in the long run.
