Tiny but Troublesome: Aphids and Chiggers in September

Not every pest is loud, obvious, or crawling all over your porch light. Some of the worst offenders in September are the tiniest — the ones you don’t notice until your plants are ruined or your ankles are on fire with bites. This month, two of the biggest troublemakers in Texas fall squarely into that category: aphids in the garden and chiggers in the yard.

Aphids: The Garden Vampires

Aphids might be small, but they travel in big numbers. These sap-sucking insects cluster on the undersides of leaves, new shoots, and flower buds. By September, after a long summer of reproduction, their populations can explode.

What homeowners notice first is the damage:

• Leaves curling and yellowing from aphids draining nutrients.

• Sticky honeydew residue on patios, cars, and outdoor furniture.

• Sooty mold growth, a black fungus that thrives on honeydew and makes plants look diseased.

  
  

Left unchecked, aphids weaken plants, stunt growth, and spread plant viruses. A fall vegetable patch or a bed of fresh mums can be wiped out in weeks. Even mature shrubs and trees can show stress when aphids are left to multiply.

What you can do:

• Spray plants with a hard stream of water to knock aphids loose.

• Prune out heavily infested leaves and dispose of them in sealed bags.

• Plant “decoy” plants like nasturtiums that draw aphids away from main crops.

• Encourage natural predators such as ladybugs or lacewings by avoiding broad-spectrum insecticides.

• Fertilize carefully — excess nitrogen gives aphids exactly what they need to multiply.

  
  

Chiggers: The Invisible Itch

On the other end of the pest spectrum are chiggers — not plant killers, but people irritators. These are tiny mites, invisible to the naked eye, that live in grassy, weedy, and shaded outdoor areas. They’re most active in late summer and early fall when families are still spending time outside for football games, backyard BBQs, and yard work.

When chiggers latch on, they inject saliva that dissolves skin cells, leaving behind intensely itchy red welts. They tend to cluster in warm spots like sock lines, waistbands, and behind knees. The itching can last for days, sometimes weeks, and scratching increases the risk of secondary infection.

How to avoid chigger bites:

• Apply insect repellent with DEET or permethrin before spending time outdoors.

• Wear long pants and tuck them into socks when walking through tall grass.

• Shower and wash clothes immediately after outdoor activities to remove any lingering mites.

• Mow lawns regularly and keep weeds trimmed, since chiggers thrive in dense vegetation.

Why These Pests Are Hard to Handle Alone

The real problem with both aphids and chiggers is their ability to rebound quickly. Aphids reproduce parthenogenetically — meaning females can clone themselves without mates. One tiny colony can turn into thousands in just a few weeks.

Chiggers, meanwhile, are resilient survivors that thrive in every patch of shaded lawn or brush pile. Home remedies like dish soap sprays or diatomaceous earth may reduce small aphid or chigger populations, but they rarely stop outbreaks during peak season.
