Texas’s vast size means red insects range from the tiny red velvet mites of the desert to the large red assassin bugs of the coastal plains. If you have noticed a red bug crawling on your porch or garden, you are likely wondering what it is and if it is dangerous. This guide will help you identify common red insects in Texas and know what to do about them.
Red bugs can be startling, especially if they are bright crimson or have a painful bite. But not every red insect is a pest. Some are beneficial predators that help control other bugs. Others are harmless but may look threatening. Knowing the difference is key to staying safe and keeping your yard healthy.

How To Identify Red Insects In Texas
Identifying red insects can be tricky because many look similar. Here is a step-by-step guide to help you figure out what you are dealing with.
- Look at the size. Tiny red bugs are likely mites or ants. Larger ones may be beetles or wasps.
- Check the shape. Long and narrow? Could be an assassin bug. Round and fuzzy? Probably a velvet mite.
- Observe the habitat. On plants? Look for milkweed beetles. In your pantry? Flour beetles. On the ground? Fire ants or velvet mites.
- Watch behavior. Are they crawling fast? Assassin bugs move quickly. Are they flying? Paper wasps or beetles.
- Note any markings. Spots or stripes can help narrow down the species.
If you are still unsure, take a photo and compare it to online guides. You can also contact your local Texas A&M AgriLife Extension office for help.
