Texas A&M recently confirmed the arrival of short-spined thrips in the Dallas area, marking a new threat to home gardens across the state. The tiny insect, which targets more than 40 plant species, was previously identified in several other U.S. states.
Why it matters
Early detection is essential for slowing the spread of this pest, as the Texas climate creates ideal conditions for the insect to persist throughout the year. The thrips can damage ornamental plants and vegetables by feeding on buds, leaves, and fruit.
These invasive thrips measure just 1 to 1.2 millimeters in length and have been confirmed on hibiscus and pepper plants. The pest, first discovered in the U.S. in 2020, now impacts Texas gardens after spreading through the ornamental plant trade.
The players
Texas A&M
A public research university that provides essential agricultural and horticultural expertise to Texas residents.
The details
Gardeners can identify the insects by placing a white sheet or surface under their plants and tapping the foliage to dislodge the tiny pests, or by using sticky traps to monitor for their presence. Because the species spreads primarily through the movement of ornamental plants, inspecting new nursery purchases is vital for prevention. Researchers have evaluated various control options, including microbial agents and biological predators like Swirski mites and minute pirate bugs, alongside specific pesticides.
Timeline
The pest was first found in Florida in 2020.
Short-spined thrips were confirmed in Texas in late 2025.
Texas A&M released formal guidance on the insect in October 2026.
The Home Front
The introduction of this pest highlights the ongoing risk of invasive species movement within the national ornamental plant trade. It follows a pattern of regional dispersal similar to that seen in Georgia, Michigan, and Colorado, where the insect has already established a presence.
Check your hibiscus and pepper plants regularly by tapping foliage over a white surface to spot any tiny, 1-millimeter insects. If you notice signs of damage on buds or leaves, contact your local county extension office for guidance on regional monitoring efforts.
The takeaway
Proactive monitoring of new nursery plants is the most effective way to prevent this pest from establishing in your home garden. Keep a close watch on your pepper and hibiscus plants during the growing season to catch infestations early.
