Frequently Asked Questions

Common questions about pest control services in Houston, TX

What should I do before a pest control visit?

Before your appointment, clear counters, move furniture slightly away from walls, secure food and pet dishes, cover fish tanks, and ensure the technician can access areas like garages, attics, and crawl spaces. Your provider will give specific preparation instructions based on the treatment type.

Can I do pest control myself instead of hiring a professional?

DIY methods can help with minor issues like occasional ants or spiders. However, infestations of termites, bed bugs, rodents, or recurring roaches typically require professional treatment. Licensed technicians have access to commercial-grade products, specialized equipment, and the training to apply treatments safely and effectively.

How do I know if I have a pest infestation?

Common signs include droppings, gnaw marks, damaged wood, shed wings near windows, unusual odors, live or dead insects, nests or webs in corners, and scratching sounds in walls or attic. If you spot any of these, a professional inspection can identify the pest species and the extent of the problem.

What is a TPCL license in Texas?

TPCL stands for Texas Pest Control License, issued by the Texas Department of Agriculture (TDA). It is required for any business performing structural pest control in Texas. The license must be renewed annually and requires proof of insurance, a certified applicator on staff, and compliance with TDA regulations.

What does it mean when a pest control license is inactive?

An inactive license means the company has not renewed their TPCL with the Texas Department of Agriculture. This could be due to business closure, failure to meet insurance requirements, or voluntary non-renewal. Companies with inactive licenses cannot legally perform pest control services in Texas.

What pests does general pest control cover?

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.

Are there dangerous spiders in Texas?

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.

Are scorpions in Texas dangerous?

The striped bark scorpion is the most common species in Texas. Its sting is painful (similar to a bee sting) but rarely medically significant for healthy adults. Children, elderly individuals, and those with allergies may have stronger reactions. If stung, apply ice and monitor for unusual symptoms. Seek medical attention for severe reactions.

What pest control challenges are unique to Texas?

Texas faces unique challenges including Formosan termite colonies in the Gulf region, fire ant infestations across most of the state, extreme heat that drives pests indoors, a long warm season that keeps pests active year-round, and a diverse geography ranging from humid coastlines to arid deserts, each with different pest pressures.

What is heat treatment for pests?

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.
