How to Prepare for Pest Control Treatment: A Room-by-Room Checklist

The kitchen is the highest-priority room. It is where most cockroach and ant activity occurs in San Antonio homes, and it requires the most preparation. Clear food, water, and clutter before your technician arrives. The goal is unobstructed access to harborage areas (under and behind the refrigerator, beneath the stove, inside cabinet hinges and the void under lower cabinets) while keeping food surfaces protected.

Remove everything from under the kitchen sink and provide clear access to that cabinet interior. This is one of the most common cockroach harborage sites in Texas homes due to plumbing moisture, and thorough treatment requires seeing and reaching all corners of that cabinet. Move small appliances away from the wall on countertops so the technician can treat behind them.

Bathrooms are secondary cockroach harborage sites, particularly in homes with American cockroaches (the large reddish-brown species common in San Antonio) that travel through sewer and plumbing connections. Clear the cabinet under each bathroom sink and provide access to the base of toilets and around the tub or shower where the floor meets the wall. If you have a bathroom with a floor-level access panel to plumbing, point this out to your technician.

Remove toiletries, towels, and other items from the floor so the technician can treat along baseboards and the junction of floor and wall without having to work around them. Bathroom preparation is quick but frequently skipped, and it is one of the reasons treatment sometimes requires a callback.

In bedrooms and living areas, the primary preparation task is clearing a path along all baseboards. Move furniture away from walls where possible, or at least create enough space for a technician to apply product along the wall-floor junction. Piles of clothing, shoes, or boxes on closet floors can block access to closet baseboards, areas where brown recluse spiders are frequently encountered in San Antonio homes.

If your treatment includes a spot treatment for spiders, clear all clutter from garage areas and storage closets the day before. Brown recluse spiders in particular are found in undisturbed clutter, and reducing this habitat before treatment improves both the contact kill and the long-term reduction in shelter availability.

Garages are frequently the highest pest activity zone in San Antonio homes, they harbor scorpions, black widow spiders, American cockroaches, and crickets year-round in the warm South Texas climate. For treatment to be effective in a garage, the technician needs access to floor-level walls and storage shelf undersides. The more clutter on the garage floor, the less effective the treatment.

For exterior perimeter treatments, pull potted plants, patio furniture, and decorative items away from the foundation wall at least two feet. This allows the technician to apply a continuous, uninterrupted barrier along the base of the structure. Sprinkler systems should be turned off for 24 hours after exterior treatment, irrigation before the product has cured is the most common cause of reduced perimeter treatment effectiveness.

Plan for pets and children to be out of the home during treatment and for a period afterward while treated surfaces dry. For most interior liquid treatments, this is 30 to 60 minutes; your technician will provide a specific re-entry time based on the products used. Have a plan in place before the technician arrives, do not wait until the service is under way to figure out where the pets will go.

Fish tanks and bird cages require special handling. Cover aquariums and turn off their air pumps before any spray treatment begins to prevent airborne product from entering the water. Move bird cages to an untreated room. Relay all of this to your technician at the start of the visit so they can plan their treatment sequence accordingly.
