Diatomaceous Earth For Boxelder Bugs
Diatomaceous Earth (DE) has gained popularity as a versatile and effective solution for pest control, and one pest in particular that it has proven effective against is the boxelder bug (Boisea trivittata). These small, reddish-brown insects are known to be a nuisance, especially in the fall when they seek shelter in homes and other structures. In this article, we will explore the characteristics of boxelder bugs, the challenges they pose, and how diatomaceous earth can be utilized as a natural and non-toxic and effective way to get rid of boxelder bugs.
Understanding Boxelder Bugs
Boxelder bugs are common pests in North America, particularly in the western and eastern regions. They feed on boxelder trees (Acer negundo), but they can also be found on maple and ash trees. During the warmer months, boxelder bugs thrive outdoors, feeding on seeds, flowers, and other plant materials. However, as temperatures drop in the fall, they seek shelter in protected areas, often invading homes, sheds, and other structures in large numbers.
Understanding the life cycle of the boxelder bug (Boisea trivittata) is crucial for effective pest control measures, including the use of diatomaceous earth. Boxelder bugs undergo a simple metamorphosis consisting of three stages: egg, nymph, and adult.
-
Egg Stage:
-
Boxelder bugs typically lay their eggs in early spring, often on the bark of female boxelder trees (Acer negundo), but they may also choose other suitable host trees like maple and ash.
-
The eggs are small, barrel-shaped, and have a creamy to light yellow color. They are laid in clusters and are often found on the sunny side of the tree trunk or on nearby structures.
-
-
Nymph Stage:
-
Once the eggs hatch, the emerging nymphs go through several molts before reaching adulthood. There are five nymphal instars in total.
-
Nymphs resemble adults in shape but are smaller and lack wings. They are initially red, turning more towards a darker shade as they molt and progress through the instars.
-
During the nymphal stage, boxelder bugs primarily feed on the sap of host trees, developing and growing in size with each molt.
-
-
Adult Stage:
-
Boxelder bugs reach adulthood in late spring or early summer after completing their final molt. At this stage, they develop fully functional wings, enabling them to disperse over longer distances.
-
Adult boxelder bugs are approximately half an inch in length and display distinctive reddish-brown coloring with narrow, elongated bodies. They have prominent wing veins, creating a unique X-shaped pattern on their backs.
-
During the warmer months, adults continue to feed on the sap of host trees and other plants. However, as temperatures drop in the fall, they begin seeking shelter to overwinter.
-
-
Overwintering:
-
Overwintering is a crucial aspect of the boxelder bug life cycle. In the fall, adults gather in large numbers on the sunny sides of buildings, houses, and other structures, seeking sheltered locations to hibernate during the colder months.
-
This behavior often leads to infestations in homes, as boxelder bugs find their way into cracks, crevices, and other entry points. They remain dormant during the winter, emerging when temperatures rise in the spring to resume their life cycle.
-
Understanding the life cycle of boxelder bugs provides insight into the timing and patterns of their activities. By targeting specific stages of their development, such as the nymphal stage when they are most vulnerable, pest control methods like diatomaceous earth can be strategically applied to disrupt the life cycle and reduce infestation risks. Incorporating this knowledge into your pest management approach enhances the effectiveness of natural and non-toxic solutions like diatomaceous earth in controlling boxelder bugs.
A Natural Solution to Boxelder Bug Infestations
While boxelder bugs are generally harmless to humans and do not cause structural damage to buildings, their presence can be a significant annoyance. When they enter homes, they can stain surfaces with their excrement, emit a foul odor when crushed, and create an overall unpleasant living environment. Traditional chemical insecticides may be effective, but they come with their own set of concerns, including potential health risks for humans, pets, and the environment.
Diatomaceous earth is a fine powder derived from the fossilized remains of microscopic aquatic organisms called diatoms. It is rich in silica and has a unique structure that makes it an effective insecticide. The sharp edges of diatomaceous earth particles are abrasive to the exoskeletons of insects, causing them to dehydrate and die. Unlike chemical pesticides, DE is non-toxic to humans and pets, making it a safer alternative for indoor use to prevent boxelder bugs.
How to Apply Diatomaceous Earth For Boxelder Bugs
To utilize diatomaceous earth for controlling boxelder bugs, follow these steps:
-
Identify Infested Areas: Determine where boxelder bugs are entering your home or where they are congregating. Common entry points include windows, doors, and cracks in walls.
-
Apply Diatomaceous Earth: Sprinkle a thin layer of food-grade diatomaceous earth in the areas where boxelder bugs are present or along their likely paths of travel. Focus on entry points and areas with high insect activity.
-
Reapply as Needed: DE is effective as long as it remains dry. Reapply after rain or if you notice the powder has been disturbed or removed. It's a good idea to reapply every few weeks during peak boxelder bug season. Use your vacuum cleaner and suck those dead bugs up!
-
Consider Outdoor Application: If boxelder bugs are a persistent problem outdoors, you can apply diatomaceous earth by mixing DE and soapy water in a spray bottle and apply directly to the surfaces of boxelder trees or areas where the bugs congregate. This can help reduce their numbers before they invade your home.
What Diatomaceous Earth Do I Use to Kill Boxelder Bugs
There are very few items that you really need to get the job done. For starters we recommend these two bundles below. The crawling insect control diatomaceous earth shares the exact composition of the food grade de, but contains an EPA label to register it as a legal pesticide. Without absorbing the us food drug administration, we are forced to ensure labeling requirements are followed as set forth by the governing bodies of the EPA and FDA. Our JT Eaton Red Insecticide Duster works well to get the product in cracks and crevices and hard to reach areas. The Diatomaceous Earth Dispenser helps you apply evenly without the worry of missing a spot, making the application too thick, or preventing an easy chore when you clean up diatomaceous earth.
