home remedies to get rid of boxelder bugsAre boxelder bugs harmful?

The box elder bug gets its name from the box elder tree which is their principal food source.

These bugs will always be found near box elder or maple trees but they have been known to feed on apple and plums trees.

The adult bugs will lay their eggs on the box elder tree in the spring, feeding on the delicate parts of the tree such as leaves, flowers, and fresh twigs, sucking the juices and sap.

During the warmer months, the bug is quite content to breed and feed in and around the tree, but it is when the weather cools, that they seek warmer climbs.

The bugs will not kill the box elder tree, but if in sufficient numbers can cause the leaves to yellow.

Migration to Mexico is not the bug’s favored vacation destination, but alas south-facing walls and crevices of your house are.

They seek small crevices and cracks, warmed by the sun, to spend the winter months and this can mean huge numbers swarming over your house, looking for a comfortable and warm place to winter.

They cause no structural damage but will stain walls and window sills if left unchecked.

The bugs are not harmful to humans and carry no diseases. Yet, if handled, they have been known to bite in self-defense. They also can create a pungent odor which has lead many people to confuse them with stink bugs.

But where they cause the most nuisance is if they manage to enter your property. Once inside, they will not lay eggs or breed but will seek out warm gaps, nooks, and crevices to overwinter.

However, when disturbed, box elder bugs will leave behind reddish fecal material which, when in large numbers, can stain fabrics and clothing.

1. Seal your home

seal home with caulkWhen treating a box elder bug infestation, it is important to deal with the bugs outside just as it is inside your home.

The bugs do not breed in your house and are just visiting, so without addressing the bugs outside, the problem will simply return the following year.

If you want to get rid of boxelder bugs inside your home first, then you need to stop the critters from entering your property in the first place.

Each house is different but do a thorough check around the house looking for potential entry points.

  • Caulking is the quickest and easiest way to block the holes, and you should do this anyway to keep the home dry.
  • Consider wire bug meshing and screens over windows
  • Use expandable foam for larger holes
  • Fit chimney caps
  • Cover vents
  • Repoint brickwork

2. Vacuuming boxelder bugs

vacuumBefore you try natural insecticides for boxelder bugs around the house, first you need to vacuum. Boxelder bugs are easy to vacuum.

If the vacuum is bagless, then disposing of the bugs is not an issue, but if you use a vacuum bag, its best to dispose of the bag after vacuuming as your vacuum will smell.

If you don’t want box elder bugs in your vacuum at all, a neat trick is to use a nylon stocking which you can insert into the vacuum pipe, fixing it with an elastic band.

The stocking effectively acts as the vacuum bag and the bugs never see the inside of your machine.

The obvious benefit of vacuuming is the speedy removal of bugs. You want to vacuum as many as possible before you try natural insecticides.

The reason is that you don’t want dead bugs in your house as their remains will encourage a much more damaging pest – the carpet beetle.

3. Boric Acid

boric acidBoric acid is a fantastic natural insecticide for boxelder bug control. Sprinkle boric acid granules on the box elder tree, around the house, on window sills, or any area where the bug congregates.

You normally purchase borax in the big grocery department stores or certain major drug stores. Borax breaks down the defensive coating of the boxelder bug, killing the bug by its damaging cell membranes and dehydrating the bug.

4.Diatomaceous earth

diatomaceous earthThis material is a sedimentary deposit which has of small fossilized materials known as diatoms. It absorbs the oils and fats from the insect’s exoskeleton causing death by dehydration.

The powder can be sprinkled liberally across the home (as you would use boric acid) as it is harmless to pets and humans. (1)

Also, spread this substance around the perimeter of the house and near the boxelder trees and any place of the yard where the boxelder bugs are likely to collect
