Identifying Assassin Bugs

Assassin bugs are predatory outdoor insects that feed on the fluids from other insects, animals, or humans. They do not feed on plants but may wander into your garden in search of other insects to feed on.

When assassin bugs are migrating, they can get attracted to the light bulbs in and around your home. If you have cracks, holes, or open windows, these bugs might find their way into your home and look for the next thing to feed on, which, unfortunately, might be you.

To avoid being on the menu for these nasty kissing bugs, it is best that you get rid of them as soon as possible. Before discussing the several ways to eliminate assassin bugs, let’s consider how to identify them.

How to Identify an Assassin Bug?

These predators can grow up to 1.5 inches and are easily identified by their broad flat backs and piercing mouthparts. They have oval, elongated bodies and prominent antennae, which they use to search for their prey.

Besides being black, brown, or orange, some species can also be gray, with yellow spots.

Ways To Get Rid Of Assassin Bugs

Before employing the methods to be discussed, thoroughly inspect your house to identify where these bugs may have nested. They are drawn to dark corners and are often found between furniture, holes in mattresses, or spaces between box springs.

When carrying out a house inspection, look out for assassin bug eggs too, as they can breed more bugs even after you’ve eliminated the adult insects. You can find clusters or rows of assassin bug eggs outside on tree stems and leaves. You can also find them in dark corners where adult assassin bugs may hide.

Outside your house, you can find adult assassin bugs hiding under cool, shady places, like rocks, debris, flower beds, or woody areas with a lot of vegetation.

Once you’ve located their hiding places, then you can begin to eliminate them using;

1. Diatomaceous Earth (D.E.)

This naturally occurring substance is one of the most effective ways to eliminate several insect pests, assassin bugs included. You can use D.E. to get rid of assassin bugs by sprinkling them in their hiding places. Its abrasive nature dehydrates and kills them within a short period. 

You can also use D.E. outside your home and in your garden. It is not a chemical, so it is safe to use around your plants as it will not cause any damage. Simply sprinkle a thin layer around the areas you find any assassin bugs.

2. Vacuuming



You can also remove assassin bugs from your property by simply vacuuming them with a handheld vacuum or whatever works best for you.

Take a vacuum to their hiding areas and vacuum away. However, this might not be the most effective method if you have not found all their hiding places.

You can use D.E. or any other friendly pesticide before following through with a vacuum for optimum results. This helps you eliminate them, ensuring you don’t leave any bugs behind.

3. Pyrethrin

Pyrethrins are organic compounds that are fatal to insects. They effectively knock them down within a few minutes and eventually kill them by attacking their nervous systems. You can purchase organic insecticides containing pyrethrin from your local store and use them to tackle an assassin bug infestation.

When applying pyrethrin, target the crevices, holes, and cracks that might house assassin bugs. Ensure you follow the instructions on the box, mix well, and apply thoroughly. You can also spray pyrethrin directly on the bugs for more effect.

Additionally, if you find any assassin bugs outside, pyrethrin will also work for outdoor use. Its nature makes it safe for use around the perimeter of gardens and around pets, so you have nothing to worry about.

4. Bug Zappers & Traps

Since assassin bugs are attracted to light, bug zappers can also effectively eliminate them. You can hang a bug zapper closest to where you notice these critters. Once they are attracted to the light, they will get zapped and fall to their death.

You can also set simple traps for assassin bugs. One way is by filling a shiny tray with soapy water and placing it below a bright light source. As the light attracts the insects, they will come close and inevitably fall into the soapy water, which you can dispose of.

Another way to set traps for assassin bugs is by fitting an electric candle inside a bottle to make a bottle trap. Once the light attracts them, they will fly close to the bottle and fall in.

You can also make a simple natural insect repellent using the following recipe;


  • Lemon eucalyptus essential oil
  • Sunflower oil
  • Spray bottle


  • Add ten drops of lemon eucalyptus oil to 8 oz of sunflower oil.
  • Shake well and allow to sit for a few minutes.
  • Pour into a spray bottle, and it is ready for use.

Assassin bugs are naturally attracted to white light. To deter them from coming close, you can exchange your white light bulbs for bulbs with a yellowish hue, as this color does not attract bugs as much.

Carry our regular fumigation inside your home and its surroundings. You can use pesticide granules or aerosols to do this. Use a nose mask when applying these chemicals, as they can be harsh.

Step 4: Remove hiding places

If your assassin bug problem only seems to worsen, contact pest control professionals to conduct thorough extermination.
