The TDA issues licenses with specific category codes: P (Pest Control), T (Termite Control), L (Lawn & Ornamental), W (Weed Control), C (Commodity Fumigation), S (Structural Fumigation), and D (Wood Preservation). Each category authorizes different types of pest management work. Notably, the P category covers rodents and nuisance animals such as rats, mice, skunks, raccoons, and opossums — there is no separate wildlife removal license.

The most common Texas pests include fire ants, cockroaches (American and German), termites (subterranean and Formosan), mosquitoes, scorpions, spiders (brown recluse and black widow), wasps, rodents, bed bugs, and fleas/ticks. The warm climate and diverse geography create ideal conditions for a wide variety of pests year-round.

Heat treatment involves raising the temperature of an infested area to 130–145°F using industrial heaters. It is the most effective treatment for bed bugs and can also treat drywood termites in localized areas. The high temperature kills all life stages including eggs. No chemicals are used, and rooms can typically be re-occupied the same day.

General pest control (Category P) covers common household pests including cockroaches, ants, spiders, silverfish, earwigs, crickets, centipedes, and occasional invaders. Some companies include mosquito and flea treatments in their general service, while others offer these as add-ons.

Texas has two medically significant spider species: the brown recluse (found statewide, especially in Central Texas) and the black widow (found throughout the state). Brown recluse bites can cause tissue necrosis, while black widow bites can cause muscle pain and systemic symptoms. Most other Texas spiders are harmless.
