Integrated Pest Management at home: a plain-English guide

Integrated Pest Management (IPM) is a step-by-step way to control pests with the least risk to people, pets and property. You inspect, identify the pest, prevent it by removing food, water and shelter, monitor with traps, use a targeted treatment only when a threshold is reached, and then check whether it worked. Pesticides are one tool, not the first move or a routine schedule.

What is Integrated Pest Management?

The EPA describes IPM as "an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices" in its IPM principles. Its introduction to IPM adds that homeowners can apply the same principles large farms use, and that the aim is to manage pests with the least possible hazard to people, property and the environment.

The EPA frames IPM in four tiers: set action thresholds, monitor and identify pests, prevent them, and control them, starting with less risky options before moving to broader pesticide use. The Texas A&M checklist below follows the same order, with an extra step at the end to check your results.

A Texas A&M AgriLife extension note on monitoring makes the point bluntly: routine pesticide applications are not considered part of an IPM program, but monitoring for a pest problem and then taking proper action is.

Several of the examples below come from Texas A&M's school IPM action plans. They were written for school buildings, but the steps carry over to a house or apartment.

Ride the fence line: how do I inspect for pests?

Inspection means looking high and low, not just where you saw one bug. The Texas A&M monitoring note points out that all pests need food, water and harborage to survive, so check where those come together:

1. Kitchen and bathrooms. Under sinks, behind and under appliances, around pipes and inside cabinets.
2. Entry points. Door sweeps, weatherstripping, utility penetrations, vents and foundation cracks.
3. Clutter and storage. Cardboard boxes, garages, closets and pantry shelves.
4. Outside the walls. Mulch and plants touching the slab or siding, leaking hose bibs and trash areas.

Use a flashlight and take notes or photos. Write down what you find, where and when.

Know the suspect: why does identification matter?

Each pest calls for a different plan. Texas A&M's action plan for sweet-feeding ants calls identifying the problem ant "the most critical step to solve a persistent problem." A German cockroach under the sink calls for a different plan than a large outdoor roach that wandered in after a storm, and a house mouse needs different exclusion than a rat.

Start with our profiles for German cockroaches, odorous house ants and house mice. If the roaches show up after heavy rain, see why roaches show up after rain. The illustrations on this site are drawings, not identification photographs, so compare the physical features with an Extension guide.

How do I prevent pests with sanitation and exclusion?

Prevention takes away what the pest needs. These steps come from Texas A&M's action plans:

German cockroaches. Texas A&M's German cockroach page says control "begins with sanitation," because removing food, water and harborage makes treatment more successful. The German cockroach action plan adds: clean up spills right away, store food in sealed containers, fix plumbing leaks, and caulk and seal hiding spots around water and food areas. The cockroach page also suggests inspecting boxes and bags as they come in, since German cockroaches often ride in.

Odorous house ants and other sweet-feeding ants. The ant action plan lists prompt spill cleanup, proper food storage and waste handling, and fixing plumbing leaks to cut off water. For exclusion, it recommends sealing cracks and crevices, trimming vegetation and pulling mulch away from the building.

House mice. Texas A&M's rodent action plan says to seal any openings greater than 1/4 inch in foundations, walls, fascia and roofs. It also recommends removing clutter, trimming vegetation near the building, and keeping trash cans away from entrances with tight-fitting lids. Our fall rodent-proofing checklist walks through sealing in more detail.

Keep watch: how do I monitor pests at home?

Monitoring shows whether a problem exists, where it is and whether it is getting better. Texas A&M's German cockroach plan calls sticky traps "the number one monitoring tool for cockroaches." Put a few along walls and under sinks, date them and check them on a schedule.

Monitoring also sets your action threshold, the point where you act. Texas A&M's monitoring note describes thresholds as boundaries between acceptable and unacceptable pest levels. The school plans give concrete examples:

• German cockroaches: one cockroach justifies baiting and monitoring, and more than five per inspection should trigger a complete review of sanitation and control (plan).
• Sweet-feeding ants: act at the first sign of a trail of six or more ants (plan).
• Rodents: one rat or mouse, or any evidence of one, justifies trapping, better sanitation and rodent-proofing (plan).

What does a targeted treatment look like?

Targeted means the least risky option that will work, placed only where the pest lives. The EPA's IPM principles say to evaluate control methods for both effectiveness and risk, starting with lower-risk options such as trapping before turning to broader spraying.

Examples you may encounter in Texas A&M guidance:

• Traps for mice. The rodent plan recommends snap traps along rodent runways with the trigger side against the wall.
• Baits for cockroaches. Texas A&M's German cockroach page describes gel baits applied in small, pea-sized placements where roaches live, and tamper-resistant bait stations where needed. Sanitation still matters, because bait has to compete with every crumb in the kitchen.
• Baits for ants, without sprays. The ant plan warns: "Do not spray pesticides when using baits." Sprayed bait is repellent to ants, and sprays can scatter the colony.

Any pesticide, including a bait, must be used exactly as its label directs. The label is the law. See how to read a pesticide label before you open anything.

How do I know whether it worked?

Keep monitoring. The German cockroach plan recommends checking baits after the first two weeks to see whether roaches are taking them, then every two weeks until traps show zero, with no nymphs or egg cases. The ant plan says to allow about six to eight weeks for baits to reduce a population. If your numbers aren't falling, go back to inspection and identification. A misidentified pest or a missed water leak is often the reason.

A one-page IPM checklist

1. Inspect kitchens, bathrooms, entry points and the outside of the walls with a flashlight.
2. Identify the pest before choosing any control.
3. Prevent by removing food, water and shelter, and by sealing gaps (1/4 inch or larger for mice).
4. Monitor with dated sticky traps and notes.
5. Treat only when a threshold is reached, starting with the least risky option that works, and follow the label.
6. Evaluate on a schedule and adjust.

When to get help

Call in help if numbers keep climbing after a few weeks of steady IPM, if you find signs of pests inside walls or attics you can't reach, or if a treatment would need equipment or protective gear you don't have. The EPA's smart pest control guidance suggests choosing a licensed company experienced in IPM. In Texas, the Texas Department of Agriculture's Structural Pest Control Service licenses professionals who apply pesticides in and around structures. For a pesticide exposure, call Poison Control at 1-800-222-1222.
