BioShield Pro Tips & Myths

Save money, exclude pests, and stop believing internet myths.

Common Misconceptions

1. Cheese Usually Is Not the Best Mouse Bait

Mice are opportunistic feeders. The best bait is often a small amount of food they are already eating; peanut butter can work, but correct trap placement and sensitivity matter more than a movie-style piece of cheese.

2. Bug Bombs Are Not a Complete Treatment

Total-release foggers may not reach pests hiding in cracks, wall voids, or clutter, and misuse can create exposure and fire hazards. Do not rely on a fogger as the only control method, never use more than the label allows, and follow all vacancy and re-entry directions.

3. Carpenter Ants Don't Eat Wood

Unlike termites, carpenter ants excavate wood instead of eating it. Galleries often begin in moisture-damaged or decayed wood but can extend into sound wood. Correct the moisture problem, then locate and address the colony rather than assuming the leak repair alone ends the infestation.

4. Do Not Count on a Fake Wasp Nest

Paper decoy nests are not a reliably proven way to prevent wasps or yellow jackets. Reduce food and water sources, seal appropriate gaps before nests form, and watch protected rooflines and voids for activity. Do not disturb an active nest if anyone nearby may be allergic.

5. Ultrasonic Plug-ins Are Not a Control Plan

Long-term pest-control claims for ultrasonic devices are not consistently supported. Rodent reactions may be temporary, and a plug-in does not replace sanitation, trapping, inspection, or exclusion. If activity continues, find the entry point and the conditions supporting it.

Exclusion (Keeping Them Out)

6. The 1/4-Inch Rule

A mouse can enter through an opening about 1/4 inch wide—roughly pencil width. Inspect where pipes, wires, vents, and utility lines enter. Use durable metal screening or mesh with an exterior-rated sealant; expanding foam by itself is easy for rodents to damage.

7. The "Light Test" for Doors

If you can see daylight around a closed exterior or garage door, pests may have a route inside. Replace worn sweeps, weather-stripping, and threshold seals, then check again from the dark side of the door.

8. Roofline Highways

Branches touching a roof or siding give ants and some wildlife an easier route to the structure. Trim vegetation away where practical and inspect soffits, fascia, vents, and roof transitions. Branch clearance helps, but squirrels can climb and jump, so it is not complete exclusion by itself.

9. Seal Exterior Lighting

Gaps around exterior fixtures can become pest entry points. Where the fixture and manufacturer permit, use exterior-rated sealant around the siding gap without blocking drainage or weep openings. Turn off power first and use an electrician if the fixture or box needs repair.

10. The Weep Hole Warning

Brick veneer needs weep openings for drainage and airflow, so do not fill them with caulk or foam. If pest entry is a concern, use a purpose-made ventilated weep cover that preserves the opening's drainage function.

DIY & Cultural Controls

11. Keep Mulch and Soil Below the Siding

Do not pile mulch, soil, or wet leaves against siding. Keep the foundation edge visible and maintain drainage away from the house. This reduces moisture and pest harborage while making mud tubes, ant trails, gaps, and damage easier to inspect.

12. Make a Weekly Mosquito Water Patrol

Once a week, empty and scrub, turn over, cover, or discard anything that holds water—buckets, toys, saucers, tires, tarps, birdbaths, and clogged gutters. For water that cannot be emptied, use only a larvicide labeled for that site and follow its directions.

13. Drain Flies and Fruit Flies Need Different Fixes

Drain flies often develop in organic film inside drains; fruit flies usually breed in fermenting food or residue. For a confirmed drain source, mechanically scrub the drain, overflow, and accessible trap surfaces, then use a product labeled for drain maintenance if needed. Bleach alone may not remove the film, and household cleaners should never be mixed.

14. Tick Prevention in the Yard

Ticks are less likely in bright, dry, well-maintained areas than in humid leaf litter and brush. Mow regularly, remove leaf litter, clear brush at lawn edges, and keep play areas away from wooded borders. These steps reduce habitat but do not eliminate tick risk, so continue repellent and tick checks.

15. Protect the Pantry

Inspect flour, grains, cereal, nuts, birdseed, and pet food for webbing or insects. Discard confirmed infested products, vacuum shelf cracks, and transfer uninfested dry goods into airtight hard-plastic or glass containers.

Sources and safe-use reminder

Pest conditions vary by property. Always read and follow the full pesticide label; never apply a product to a pest, site, or surface not listed on that label.
