Manual, Heat Treatment and Fumigation Options
- 1. Bed Bugs Manual, Heat Treatment and Fumigation Options Dale Hodgson, BCE Regional Technical Manager ROSE PEST SOLUTIONS Lead with Quality and Enthusiasm ! Central Ohio Bed BugTask Force September 7, 2018
- 2. Inspection……human, canine, monitoring Before Doing Anything…… Finding bed bugs in the first place
- 3. A bite is a bite is a bite? Before Doing Anything…… Finding bed bugs in the first place
- 4. Bed Bugs vs Bat Bugs vs…….. Chimney Swift Bugs Before Doing Anything…… Make SureYou Know ExactlyWhatYou’re Dealing With
- 5. Construction Clutter Furniture Once Identified…… DeterminingWhich Method is Best…one, the other or a combo ?
- 6. Determined by treatment method chosen • Rule of thumb is prep for the most effective treatment Heat is a little different than manual • Heat is a little less intensive but not much…. Fumigation is radically different from the others • We will get into that in a bit…. Preparation
- 7. • Clear floor of clutter • Strip beds (box springs will be leaned against wall; ticking will be removed) • Wash bedding and replace after treatment • Empty drawers, night stands, desks, etc. • Check items for bed bugs, place in plastic bags or containers if infested and discard • Do the laundry…all the laundry • Move furniture away from walls • Window treatments are inspected…if infested should be steam cleaned • Check pet areas; launder bedding • Remove “personal items”…if you leave them we WILL find them ManualTreatment Prep
- 8. HeatTreatment Checklist Pressurized cans and containers: Fire extinguishers, shaving cream, aerosol cans (hairspray, bug spray, deodorant, non-stick cooking spray), etc. Flammable materials: Propane, Sterno®, cigarette lighters, lighter fluid, mineral spirits, paint thinner, etc. Items that melt: Candles, wax, crayons, candy, chocolate, etc. Sealed jugs of liquid that may burst or split Antifreeze, bleach, ammonia Live plants, aquarium fish, and pets of any kind.
- 9. HeatTreatment Checklist Delicate instruments and equipment Guitars, violins, and other delicate musical instruments as well as oil paintings and other heat sensitive art objects. Pianos do not need to removed; they may need to be tuned after the treatment. Medical equipment and materials: Oxygen bottles and generators, medications (liquid, gel-caps, prescriptions), etc. Power chairs may have to remain in the treated space if bed bug activity is discovered on the chair. Sealed batteries/power packs must be removed Miscellaneous items: Fresh fruit, heat sensitive cosmetics, ammunition.
- 10. HeatTreatment Checklist The heat will penetrate most household materials and spaces, but we want to ensure there are no cool spots for bed bugs to hide. Household goods and personal items should not be stacked, piled, or stored in plastic bags during the heat treatment. Densely packed plastic bags do not allow proper heat penetration or inspection during the treatment and could adversely affect the results of the treatment. Instead of plastic bags we recommend mesh type laundry bags which are readily available at most retailers. All fabric items (linens, blankets, clothes, etc.) should be loosely stacked or in drawers. If drawers are tightly packed, they should be emptied, at least partially, so heated air can circulate around them. Loose clothing removed from drawers can be stored in open-weave clothes baskets or mesh laundry bags. DO NOT put clothes into plastic bags.
- 11. HeatTreatment Checklist Clothes in closets should hang loosely. If tightly packed, clothes should be taken out and hung on portable racks to facilitate air circulation. We use fans to distribute the heated air. Loose papers should be secured in some way (paper clips, binders) to keep them from blowing around. Move delicate, fragile and personal items to a safe place in order to prevent accidental damage. Water beds must be drained; air beds (such as Select Comfort) must be partially deflated.
- 12. Fumigation (Tape and Seal) Clothes in closets should hang loosely. If tightly packed, clothes should be taken out and hung on portable racks to facilitate air circulation. We use fans to distribute the heated air. Loose papers should be secured in some way (paper clips, binders) to keep them from blowing around. Move delicate, fragile and personal items to a safe place in order to prevent accidental damage. Very little actual prep; remove articles that are needed for the next 24-36 hours
- 13. Advantages • Treatment happens quickly once prep is done • Can be done with/without “conventional” pesticides • DE’s (Mother Earth D), Silica Aerogel (Cimexa) • Vacumming, steam, Cryonite • Lower cost Disadvantages • Extensive prep on client’s part • Residents must vacate • Odors may be present shortly afterwards ManualTreatments
- 14. What is working • Available products seem to be working • Some are slow; others areVERY slow • Combination products (Temprid,Transport) seem to work well • Still have to match the product with the substrate (old school still holds true) • Example would be use a microcap or suspension on porous materials • Dusts have been overlooked but shouldn’t be • Extremely valuable tool for voids and “oddball” gaps in furniture What we are finding out • Bed bug behavior is different • Tend to not rest on surfaces treated with deltamethrin but will rest upon other pyrethroids • Thoroughness of preparation and treatment is a priority • Can be thought of as an “old school” cockroach treatment ManualTreatments
- 15. Advantages • Most items remain • Can be done with/without “conventional” pesticides • DE’s (Mother Earth D), Silica Aerogel (Cimexa) • Vaccuming, steam, Cryonite • Results achieved quickly (except for those “dead bugs walkin’”) • Eliminates all stages from egg-adult • A little less intensive prep on client’s part • Residents return home the same day Disadvantages • Residents must vacate for 6-8 hours • Higher cost HeatTreatments
- 16. How it works • 80- 85 degrees F is optimum for bed bug development • Once temps reach 112-115 heat becomes lethal after 90 min. exposure • 118 for 20 minutes is lethal • Doesn’t mean that bed bugs aren’t inVegas…they are! What we’ve learned along the way • Construction matters! • Deep protected double voids can provide a safe haven • Air circulation matters • Convective air currents make heating more efficient • Materials treated matter • Some materials (porcelain, ceramics are very insulating) HeatTreatment
- 17. Advantages • Less prep than manual; more than a heat treat • Can be done with/without “conventional” pesticides • DE’s (Mother Earth D), Silica Aerogel (Cimexa) • Vacuuming, steam, Cryonite • Results achieved quickly (except for those “dead bugs walkin’”) • Eliminates all stages from egg-adult • A little less intensive prep on client’s part • Residents should be able to return home the same day Disadvantages • Residents must vacate for 6-8 hours • Higher cost because of heat equipment involved ComboTreatments
- 18. The Order of Business… • Which is done first; heat or application? • Depends on what is going to be used • Dusts in wall voids may help intercept movement during heating • Cannot be applied once circulation fans are in use • Liquid residuals for crack and crevice work • Can be done either before or after; thermal breakdown was formally a concern but has largely been dismissed by the manufacturers • Vaccuming, steam, Cryonite • Can be done before or after; not a good idea during ComboTreatments
- 19. Advantages • Most items remain • Done with/without “conventional” pesticides • Results achieved quickly ( 24 hours ) • Eliminates all stages from egg-adult • A lot less intensive prep on client’s part Disadvantages • Residents must vacate for 24-36 hrs • Very high cost • Absolutely NO residual left once treatment is done – open to reinfesttion Fumigation (Tape and Seal)
