Kissing Bugs in Collin County, TX | Identification and Control

Last updated October 2026

The kissing bug is a blood-feeding conenose bug that comes out at night, flies to porch lights and can crawl in through gaps around doors. The Texas A&M Kissing Bugs and Chagas Disease program puts an adult at 1/2 to 1 inch long, black or dark brown with an orange, red or yellow banded edge. Some carry the parasite that causes Chagas disease, which travels in the bug’s droppings, not its bite.

What Does a Kissing Bug Look Like?

A dark bug with a long, cone-shaped head, thin legs and a banded edge around its body

An adult kissing bug has a long, narrow head shaped like a cone, a pear-shaped black or dark brown body and long, thin legs with no thick sections. Most kinds have a band of orange or red markings around the edge of the body, and the Texas A&M Kissing Bugs and Chagas Disease program says adults are 1/2 to 1 inch long from the tip of the nose to the end of the body. The mouthparts are straight and thin and fold under the body when the bug is not feeding.

The two kinds most often found in this part of the country look a little different. The program’s questions page says Triatoma sanguisuga, the eastern conenose bug, has dark red stripes, while Triatoma gerstaeckeri, common in Texas, has yellow orange stripes. Both are about an inch long. The young look like small adults without wings, and only adults can fly.

Dead GiveawaysThe signs that point to a kissing bug rather than a look-alike
  • A long, narrow, cone-shaped head with the antennae near its tip
  • Orange, red or yellow bands around the flat edge of the body
  • Long, thin legs with no thick or flattened sections
  • A straight, thin beak folded under the head, not a thick curved one
  • Found at night near a porch light, a door or a dog bed
  • Small red bites found in the morning, often on the face, hands or arms
Other Names

Other Names for the Kissing Bug

The name comes from the face. The Texas A&M program says people used to think these bugs mostly bit around the mouth or eyes, like a kiss, though they bite anywhere they can reach. Conenose bug describes the long head, and in Spanish they are called chinches, or vinchucas, a name the Texas Department of State Health Services also uses. Scientists call the whole group triatomine bugs.

The name that causes the most confusion is assassin bug. Kissing bugs belong to the same insect family, but assassin bugs such as the wheel bug hunt other insects and do not carry the Chagas parasite. The look-alike table below shows how to tell them apart.

How to Tell a Kissing Bug from a Wheel Bug, Stink Bug or Bed Bug

Many bugs around Collin County homes get mistaken for kissing bugs, and the Texas A&M program says it has been overwhelmed with photos of look-alike bugs. The head, the legs and the beak tell them apart.

The kissing bug compared with the bugs most often mistaken for it
Species Size and Color Key Feature Where Found
Photo of a kissing bug
Kissing Bug AKA: Conenose Bug, Chinche Triatoma species This species
1/2 to 1 inch. Black or dark brown with an orange, red or yellow banded edge. Long cone-shaped head, thin legs with no thick parts, a straight thin beak. Animal nests, brush and dog kennels, and at night near lights and doors.
Wheel Bug AKA: Assassin Bug Arilus cristatus
Mostly gray. A raised half wheel shape on its back and a thick, curved beak. Gardens, shrubs and trees, hunting other insects.
Photo of a stink bug
Stink Bug AKA: Shield Bug Pentatomidae
Brown, gray or green, with a broad shield-shaped body. A short, wide head with no long cone nose. On garden plants, and on outside walls and windows.
Photo of a bed bug
Bed Bug AKA: Common Bed Bug Cimex lectularius
Far smaller, flat, oval and reddish brown. No wings and no long cone nose. Inside, in mattress seams, bed frames and furniture.
Leaf-Footed Bug AKA: Leaffooted Bug Leptoglossus species
Brown adults, with bright red young that gather in groups. Wide, flattened back legs and no long cone nose. On fruit, vegetables and garden plants.

Kissing Bug vs Wheel Bug

A kissing bug and a wheel bug are cousins, so start with the beak and the back. The Texas A&M kissing bug identification sheet says a kissing bug has a straight, thin beak, while look-alike assassin bugs have a thick or curved one, and a wheel bug carries a raised half wheel on its back. Then check the legs. Wide, flat back legs mean a leaf-footed bug, and a broad shield shape with a short head means a stink bug. A wheel bug can give a painful bite if handled, so move any of them with a container, not your fingers.

The Kissing Bug in Three Numbers

1/2 to 1 inch

The Texas A&M Kissing Bugs and Chagas Disease program says an adult kissing bug is about 1/2 to 1 inch long, from the tip of its cone-shaped nose to the end of its body.

Texas A&M Kissing Bugs and Chagas Disease program

About 20 days

A 2007 laboratory study in Memórias do Instituto Oswaldo Cruz found that eggs of the Texas kissing bug Triatoma gerstaeckeri and two related kinds took about 20 days to hatch.

About 55%

The Texas A&M Kissing Bugs and Chagas Disease program found that about 55 percent of the more than 7,000 kissing bugs people sent it since 2012 carried the parasite that causes Chagas disease.

Why Kissing Bugs Score 2 of 3 on People Risk

People Risk for Kissing Bugs

Some kissing bugs carry the parasite that causes Chagas disease, a serious illness, but it spreads through the bug’s droppings rather than its bite, and catching it from a bug in Texas is uncommon.

Are Kissing Bugs Dangerous?

They can be, but usually are not. The risk is Chagas disease, caused by a parasite some kissing bugs carry in their gut. The Texas A&M Kissing Bugs and Chagas Disease program found that about 55 percent of the more than 7,000 kissing bugs people sent it since 2012 carried that parasite. Even so, the Texas A&M AgriLife Extension fact sheet on conenose bugs says that for most people bitten in the United States the worst result is redness and itching where the bug fed.

What Does a Kissing Bug Bite Look Like?

There is no typical kissing bug bite. The Texas A&M program says most people do not feel the bite, that reactions run from nothing at all to a severe allergic reaction, and that you cannot tell what bit you just by looking at the mark. The AgriLife fact sheet adds that bites usually happen during sleep, most often on the face, hands and arms, and are found the next morning as red spots. Anyone worried about a bite should talk to a doctor, and anyone with swelling of the lips or throat or trouble breathing needs emergency care.

How Do You Get Chagas Disease From a Kissing Bug?

Through the droppings, not the bite. The Texas Department of State Health Services page on Chagas disease explains that an infected bug can leave droppings while it feeds, and the parasite gets in when a sleeping person rubs them into the bite, a cut, an eye or the mouth. The same page says human cases caught in Texas do occur but are uncommon, that early signs can include fever, body aches, a rash or swelling of one eyelid, called Romaña’s sign, and that most people with long-term infection never have symptoms, though 20 to 30 percent develop heart or digestive problems. Tests and treatment exist, so see a doctor if you think you have been exposed.

Context

When a Kissing Bug Needs Fast Action

High Priority

Swelling or Trouble Breathing

A bite followed by swelling of the face or throat, hives or trouble breathing is a severe allergic reaction. Call 911.

High Priority

A Bug in a Bed or Bedroom

Keep the bug in a sealed bag or jar and call your doctor. The state health department tests bugs found in bedrooms or tied to a bite.

Moderate

Wingless Young or Several Adults

Young bugs without wings, or more than one adult indoors, suggest the bugs are breeding in a nest close to the house.

Low

One Adult by the Porch Light

A single adult that flew to a light is not cause for alarm. Catch it safely, check the doors and screens, and turn the light off at night.

Indoors

Why You Have Kissing Bugs Around Your House

Kissing bugs live where their hosts sleep. Outdoors that means woodrat nests, raccoon and opossum dens, brush piles and dog kennels, and they fly at night toward lights. A Texas A&M study of 3,215 bugs collected from 2012 to 2016, published in the American Journal of Tropical Medicine and Hygiene, found that 92.9 percent of the bugs people collected were found indoors, around the house or in dog kennels.

From a porch light they crawl in through gaps around doors, torn window screens and doors left open without a screen. The Texas A&M AgriLife fact sheet notes that one bug in the house is not a reason to panic, because a single adult is usually a stray from outside. Young bugs without wings, or several adults, point to a nest nearby, often in a wild animal den, a woodpile or a dog house.

Property Risk for Kissing Bugs

Kissing bugs feed only on blood, so they do not chew, stain or damage anything in the house. The concern is the people and pets they feed on, not the building.

Habitat

Where Kissing Bugs Live Around Collin County Homes

Kissing bugs stay close to the animals they feed on. The Texas A&M program lists woodrats, raccoons, coyotes and opossums among the wild animals that carry the parasite, and the state health department points to brush piles, rock piles, deep leaf litter, dog houses and chicken coops as places the bugs hide. Homes that back onto creeks, greenbelts or open land have more of those hosts close by.

Local Presence

Kissing Bug Pressure Across Collin County

Kissing bugs are not a common call for us in McKinney, Frisco, Allen or Plano. They are still worth knowing, because the Texas Department of State Health Services says both the bug and the parasite are present in all regions of Texas, and Texas A&M’s collections found the eastern conenose bug mostly in the northern and eastern parts of the state.

In Celina and Prosper, where newer homes border open land, creeks and brush, the woodrats, raccoons and opossums the bugs feed on can live closer to the house, along with the outdoor dog kennels the bugs are drawn to.

Why Kissing Bugs Score 1 of 3 on Persistence Risk

Kissing Bug Biology and Seasonal Presence

Kissing bugs grow slowly and breed in wild animal nests, not in a tight, well-kept house, so most finds indoors are single adults that flew in during the summer.

Behavior and Biology

How Kissing Bugs Grow and Feed

Eggs Hatch in about 20 days The eggs are small, oval and light colored. A 2007 laboratory study in Memórias do Instituto Oswaldo Cruz found they hatched in about 20 days for Triatoma gerstaeckeri and two related kinds.
Growth Five young stages, seven months or more The young pass through five stages before they grow wings, and need blood before each step. In the same study, egg to adult took seven months or more.
Feeding Several minutes a meal The Texas A&M program says kissing bugs feed on blood their whole lives, many times over, and take several minutes to finish a meal. They do not stay attached like ticks.
Lifespan Up to two years Some kinds of kissing bug can live up to two years, according to the Texas A&M program, which is why a nest under a woodpile or in a den can keep producing bugs.

How to Get Rid of Kissing Bugs

Kissing bugs come from the animal nests, brush and kennels around a home, not from inside it. What works is treating where they hide and where they get in, and taking away the lights and cover that draw them close.

How Pest Me Off Gets Rid of Kissing Bugs

Kissing bug control is four steps, every job. Most of the work happens outside, because the bugs breed in the nests and cover around the house and only wander in.

Step 1

Inspect and Identify

A free inspection of the doors, screens, porch, garage, dog areas and the brush and woodpiles near the house. We confirm it is a kissing bug and not a wheel bug, stink bug or leaf-footed bug, and look for the nests feeding them.

Why this step: Many bugs people send in as kissing bugs are look-alikes. Treating for the wrong bug wastes the visit and the worry.
Step 2

Treat Where They Hide

A treatment around dog houses and kennels, woodpiles and the cover along the foundation, the places the Texas A&M AgriLife fact sheet names as hiding spots.

Why this step: The bugs at the door come from the nests nearby. Leave those spots untreated and more fly in next summer.
Step 3

Guard the Way In

A treatment along the base of the house, the door and window frames, the thresholds and the garage, the spots kissing bugs cross on their way inside.

Why this step: Kissing bugs land near a light and crawl in under doors. Stopping them at the edge of the house keeps them out of the bedrooms.
Step 4

Take Away the Draw

We show you what is drawing them, from porch lights left on and gaps under doors to torn screens, brush piles and pet bowls left outside, and what to change.

Why this step: Lights pull the adults in and wild animal nests feed them. Change those and the next summer is quieter.

DIY Management

How to Get Rid of Kissing Bugs Yourself

Most DIY kissing bug work is keeping them out and away. The Texas A&M program and the state health department both put sealing and cleanup first.

1
Seal the way in. Plug gaps around doors and baseboards, fix holes in window screens, and never leave a door or window open without a screen.
2
Take away lights and cover. Turn off outdoor lights at night where it is safe, clear brush, rock and wood piles and old animal nests, control rodents, and keep pet food and water bowls inside.
3
Handle a found bug safely. Use a glove or a small plastic bag, never bare hands, and keep the bug sealed in a bag or jar. The Texas A&M program says to note the date, time and place, freeze the bug for a few hours, clean the spot with a bleach solution, and send a photo through its online form.
DIY Pitfalls

Why Some DIY Responses Fail for Kissing Bugs

Most DIY kissing bug trouble comes from touching the bug, guessing from a bite mark, or leaving dogs and their food out where the bugs feed.

Makes It Worse

Crushing It With Bare Hands

The parasite lives in the bug’s droppings and can be on its body. Squashing one with your fingers can put the parasite on your skin.

Misleads You

Judging by the Bite Mark

A bite mark cannot tell you what bit you. Keep the bug if you can, and talk to a doctor about any bite that worries you.

Puts Pets at Risk

Dogs and Bowls Left Outside

Dogs can catch the parasite by eating kissing bugs, and outdoor dogs face much higher risk. Bowls left out can be fouled by droppings.

Operational Questions

Common Kissing Bug Questions

What is a kissing bug?
A kissing bug, or conenose bug, is a blood-feeding insect that is active mostly at night and feeds on people, dogs and wild animals. Some carry the parasite that causes Chagas disease. It has a long cone-shaped head, thin legs and, in most kinds, an orange, red or yellow banded edge around a black or dark brown body.
How big are kissing bugs?
Adults are about 1/2 to 1 inch long from the tip of the nose to the end of the body, according to the Texas A&M Kissing Bugs and Chagas Disease program. The two common kinds in this part of the country, Triatoma sanguisuga and Triatoma gerstaeckeri, are each about an inch long. The young are smaller and have no wings.
What does a kissing bug bite look like, and does it hurt?
Most people do not feel it, because the beak is as thin as a tiny needle. There is no typical mark. Some people have almost no reaction and a few have a severe allergic reaction, and a bite cannot be identified just by looking at it. Bites usually happen during sleep, often on the face, hands or arms. Talk to a doctor about any bite that worries you.
Can you get Chagas disease from a kissing bug bite?
Not from the bite itself. The parasite is in the bug’s droppings, not its saliva, and infection happens when droppings are rubbed into the bite, a cut, an eye or the mouth. The Texas Department of State Health Services says human cases caught in Texas occur but are uncommon. If you think you were exposed, see a doctor, because tests and treatment are available.
What should I do if I find a kissing bug in my house?
Do not touch it with bare hands. Catch it with a glove or a small plastic bag, seal it in a bag or jar, and clean the spot with a bleach solution. Write down the date, time and place. The Texas A&M program identifies bugs from a photo sent through its online form, and a bug found in a bedroom or tied to a bite can be sent to the Texas Department of State Health Services for testing.
Are there kissing bugs in Collin County?
Yes, though they are not a common find. The Texas Department of State Health Services says the bug and the parasite are present in all regions of Texas, and Texas A&M’s collections found the eastern conenose bug mostly in the northern and eastern parts of the state. Texas has more kinds of kissing bug, and more finds, than almost any other state.
Can my dog get Chagas disease from kissing bugs?
Yes. Dogs can be infected by eating kissing bugs, and the state health department says outdoor dogs face much higher risk. In dogs the disease can cause heart problems, though many infected dogs show no signs. A blood test is available through the Texas Veterinary Medical Diagnostic Laboratory, so talk to your veterinarian if you are worried.
Is it a kissing bug or a wheel bug, stink bug or bed bug?
Look at the head, the legs and the beak. A kissing bug has a long cone-shaped head, thin legs and a straight thin beak. A wheel bug has a raised half wheel on its back and a thick curved beak, a stink bug has a broad shield shape and a short head, a leaf-footed bug has wide flat back legs, and a bed bug is far smaller, with no wings and no cone nose.
What do kissing bug eggs look like, and how long do they take to hatch?
The eggs are small, oval and light colored. A 2007 laboratory study in Memórias do Instituto Oswaldo Cruz found they hatched in about 20 days for Triatoma gerstaeckeri and two related kinds, and that growing from egg to adult took seven months or more. The young pass through five stages without wings before becoming adults.
Why are they called kissing bugs?
People used to think they mostly bit around the mouth and eyes, like a kiss. The face is a common spot because it is often uncovered during sleep, and the bugs generally cannot bite through clothing, but they will bite the hands, arms, feet or anywhere else they can reach.
How do I get rid of kissing bugs?
Keep them out and take away what draws them. Seal gaps around doors and baseboards, fix torn screens, turn off outdoor lights at night, clear brush, woodpiles and animal nests near the house, and keep pets and their bowls inside at night. Where bugs keep turning up, a pest professional can treat the hiding spots and the ways in.
