Pasadena’s homes have a median year built of 1977, and 56.7 percent were built before 1980. Paper wasps hang their nests under eaves and also in garages, sheds and shrubbery, where a nest can reach 6 to 8 inches across. Yellow jacket nests are mostly underground, though some sit under eaves. The provider confirms the insect, how big the nest is and how to get to it.

Texas has just one insect called a hornet, the baldfaced hornet, and the Texas Apiary Inspection Service says it is really a yellow jacket. It builds a big, closed gray paper nest high in a tree, in shrubbery or below the eaves. Ask the provider how they intend to get to a nest that sits that high.

Yellow jacket nests are mostly in the ground, where one step or a pass of the mower can stir up the colony, and some end up inside a wall. Leave a wall opening alone: AgriLife says it should not be sealed until the colony is eliminated, or the wasps may come out indoors. The provider decides the treatment.

In Pasadena, 30.5 percent of housing units are in buildings of five or more units, so many nests turn up on balconies, stairwells and eaves that residents do not manage. Renters tell the manager, who sets up access, and a provider names the insect, treats the nest and checks the spots around it.

Paper wasp queens often start new colonies in the same general area each spring, and in a mild winter a yellow jacket nest may hang on, so some providers schedule a return visit to check eaves, sheds and garages and treat any activity. Ask before work starts whether a return trip is included.
View serviceThe provider tracks down the nest and its openings, works out whether paper wasps, hornets or yellow jackets live there, and gauges its size. Ask what they saw before work starts.
Bring children and pets inside and move toys and outdoor furniture away. Do not spray or plug the opening yourself, which can send wasps toward the house, and follow whatever the provider asks of you.
The colony is treated, often early or late in the day while most of the wasps are inside. When the nest goes quiet and can be reached, it usually comes down and the opening is handled.
Paper wasp queens often rebuild in the same general area the next spring. Ask if a return visit is part of the plan and which spots to keep an eye on, such as eaves, porch ceilings, sheds and garages. Keep away from the area until the provider says it is clear.
Each provider uses its own methods, yet most visits move through these four stages. Ask the provider to walk you through them, including the timing and anything to do before or after.
Anyone looking up wasp removal in Pasadena, TX gets a long list of ads and directory pages. This site offers a single number instead: tell an independent provider who works in Pasadena about the nest, and then decide for yourself whether to book a visit.
Before work starts, check the provider’s license on the Texas Department of Agriculture’s current-license list. TDA’s Structural Pest Control Service licenses businesses, certified applicators and technicians, and its lists can be downloaded. This site does not screen or endorse any provider.
Honey bees need a different route, and this line does not take those calls. Fuzzy, golden-brown bees working on wax comb should go to a beekeeper on the Texas Apiary Inspection Service list for Harris County, where Pasadena sits. Do not spray chemicals into a hive.
The line covers addresses in 77502, 77503, 77504, 77505 and the Pasadena part of 77506. Calls are connected 6 a.m. to midnight Central Time (7 a.m. to 1 a.m. during daylight saving time).
Sometimes. Texas A&M AgriLife notes that paper wasp queens often found new colonies in the same general area the next spring, and in a mild winter a yellow jacket nest may not be abandoned at all. Ask the provider which places to keep an eye on and whether a return visit is part of the plan.
The safe part is watching from well back: note where the nest is, its height and whether wasps are flying in and out. Swatting it down, spraying it or plugging the hole can bring a burst of stings and drive the colony indoors. AgriLife says that if you have any doubt about your ability to safely control a wasp nest, call a professional.
Do not caulk or tape over the hole. Texas A&M AgriLife advises that a yellow jacket entrance in a wall generally should not be sealed until the colony has been eliminated, because trapped wasps may hunt for a new exit, which can lead inside. The provider chooses the treatment and says when the gap can be closed.
This site lists no amounts. A provider works out the charge after seeing the job, and the main factors are the insect involved, the colony’s size, the nest’s height or hiding place, wall or ground access, and any return trip. Before agreeing, ask exactly what the visit includes and whether a follow-up is part of it.
Texas A&M AgriLife says yellow jacket colonies peak by August or September and most nests die after the first hard frost, though in a mild winter a nest may survive. Houston Hobby Airport, the weather service site nearest Pasadena, averages only 4.2 days a year at or below 32°F. Paper wasp queens rest over winter and start new nests in spring.
