I live in Amman-Jordan and I keep finding this bug species on my walls. I saw four till now on the walls of another room. A little bit bigger than the first one.

I also have a video, but don't know how to post it.

  • $\begingroup$ Hi Rashah. Please provide an approximate size of this insect. If you can, also provide a clearer picture. Your photo quality makes this insect difficult to ID accurately. Could be a bedbug, but might also be a beetle (perhaps a grain beetle). A better photo will help us ID this accurately for you, so please edit. Thanks. $\endgroup$ Commented Apr 1, 2019 at 15:22
  • $\begingroup$ I don't know if that will help but the walls I keep finding it on has some mildew on them. Though I sprayed the wall with vineger. Nothing on my bed. No bites on any of my family members. And it's brownish red with naked eye $\endgroup$

  • $\begingroup$ Regarding your video. Try uploading it to ezgif.com, convert it to a gif file (optimizing to get it below 2mb) and then you can post it directly into your post. You could upload the whole video to youtube and link to it as well. $\endgroup$ Commented Apr 2, 2019 at 16:09

1 Answer 1


These are very likely flour beetles (Tribolium spp) of some kind. These small (~3mm) reddish-brown beetles are some of the most widespread and common pests of stored food products worldwide [source].

The photo is too blurry to be able to differentiate between the most likely candidates: red flour beetle (T. castaneum) and confused flour beetle (T. confusum).

  • You can learn more about differentiating these insects here and here, and you can find more general information about them via UF/IFAS.

Distribution: Both species are essentially found worldwide; This UF/IFAS page provides a bit more nuanced explanation of their distribution:

The red flour beetle is of Indo-Australian origin (Smith and Whitman) and is found in temperate areas, but will survive the winter in protected places, especially where there is central heat (Tripathi et al. 2001). In the United States, it is found primarily in the southern states. The confused flour beetle, originally of African origin, has a different distribution in that it occurs worldwide in cooler climates. In the United States it is more abundant in the northern states (Smith and Whitman).

Extermination tips are available via epetsupply.com:

  • Prevention is key!
  • Keeps your home clean and free of food/crumbs
  • Sticky traps and pheromone traps

If I had to guess, I'd guess from your poor images that you have red flour beetles, but honestly it doesn't much matter from a pest-control standpoint.

The red and confused flour beetles live in the same environment and compete for resources (Ryan et al. 1970, Willis and Roth 1950). The red flour beetle may fly, especially before a storm, but the confused flour beetle does not fly. [source: UF/IFAS]


Alternatively, now that I've looked at your picture with such a small specimen, it could be possible this is another "grain beetle": Ahasverus advena, the foreign grain beetle. From Wikipedia:

enter image description here

Source: Wikipedia

Description: The foreign grain beetle is approximately 2 mm (​1⁄12 in) in length. It can be distinguished chiefly by slight projections or knobs on each front corner of the pronotum, and its club-shaped antennae. The larvae are worm-like, cream-colored and often reach a length of 3 mm before pupating into darker adults. Males and females are identical in appearance both as larvae and adults. The adult is usually reddish brown, or sometimes black.

Distribution The foreign grain beetle is found in tropical and temperate regions [and is distributed all throughout the world -- see Spanish translation of Wikipedia page].
