Hitchhiking Walking down a hallway after dropping off an item from an infested room to new territory from one room to another via pipes, telephone, cable or electrical wires </li> <li> Slide 13 </li> <li> Bed Bugs In Schools Brought in by students, staff, visitors, etc. Bugs crawl into the schools chairs, carpeting, equipment, etc. A single bed bug does not warrant panic or school closure! </li> <li> Slide 14 </li> <li> Control of Bed Bugs In Schools Early identification is very important Staff should be trained re. what to look for Maintenance and cleaning crews should be on the lookout for telltale signs of bed bugs Capture a bug for positive identification </li> <li> Slide 15 </li> <li> INTEGRATED PEST MANAGEMENT (IPM) FOR BED BUGS: Correctly identify the pest + Conduct a thorough inspection + Use sanitation measures + Apply insecticides to targeted sites </li> <li> Slide 16 </li> <li> LIFE CYCLE OF THE BED BUG (Cimex lectularius) Adult (male &amp; female ) ~0.26 inch (6.5 mm) long Takes repeated blood meals; life span ~1 to 1 yrs 4 th stage nymph ~0.12 inch (3 mm) long Takes a blood meal then molts 2 nd stage nymph ~0.08 inch (2 mm) long Takes a blood meal then molts 5 th stage nymph ~0.18 inch (4.5 mm) long Takes a blood meal then molts Egg ~0.04 inch (1 mm) long Glued in place 3 rd stage nymph ~0.1 inch (2.5 mm) long Takes a blood meal then molts Note: These images depict bugs with a partly digested blood meal. 1 st stage nymph ~0.06 inch (1.5 mm) long Takes a blood meal then molts The Ohio State University Dr. Susan C. Jones &amp; Benjamin R. Diehl </li> <li> Slide 17 </li> <li> --IDENTIFICATION-- Shape and Size Beak-like mouthparts Oval shaped Body flattened (unfed) to swollen (recently fed) Adults: ~1/4 3/8 inch long Youngest nymphs (immature bugs) are tiny ( </li> <li> Launder bedding, clothing, etc.! Wash in hot water (&gt;120F, [50C]) Drier on hot setting (&gt;30 minutes) Some measures to help reduce the number of bed bugs: </li> <li> Slide 45 </li> <li> Treatment Options Heat treatment (whole structure, container) Cold (usefulness is limited) Insecticides Residual products (dust, liquid, aerosols) Fumigation (sulfuryl fluoride) </li> <li> Slide 46 </li> <li> 120 F for several hours Portable Thermal Chamber Containerized Heat Treatment </li> <li> Slide 47 </li> <li> Whole Room Heat Treatment </li> <li> Slide 48 </li> <li> Cold Treatment </li> <li> Slide 49 </li> <li> Bug Bombs (foggers) wont control bed bug infestations Bug Bombs may cause bed bugs to scatter!!! Bug Bombs can worsen the bed bug problem!! What shouldnt you do for a bed bug problem? </li> <li> Slide 50 </li> <li> October 2012 http://pct.texterity.com/pct/201210#pg1 </li> <li> Slide 51 </li> <li> cockroach feces cockroach shed skin bed bugs nearby </li> <li> Slide 52 </li> <li> Typically, you shouldnt dispose of furniture. Bed bugs will fall off the furniture as you are moving it, hence spreading the problem. Infested furniture usually can be treated. Bed bugs can quickly infest replacement furniture. Items placed on the curb often are picked up and reused, thereby spreading bed bugs to other households. What shouldnt you do for a bed bug problem? </li> <li> Slide 53 </li> <li> Must be sprayed directly on the bed bugs (kills on contact) Most bugs are hiding and WILL NOT be killed Little or no residual activity (the chemical breaks down quickly) BUYER BEWARE: Grocery store insect sprays wont eliminate a bed bug infestation! </li> <li> Slide 54 </li> <li> Words of caution regarding natural products for bed bug control: Exempt from EPA regulation EPA requires no efficacy data Claims often based on satisfied customersask for their research data and evaluate it carefully </li> <li> Slide 55 </li> <li> Boric acid does not kill bed bugs. Boric acid is a stomach poison that must be eaten by an insect. Remember that bed bugs feed only on blood. BUYER BEWARE: Boric acid products dont work! </li> <li> Slide 56 </li> <li> Some Basics of Bed Bug Management Using Insecticides There is no single magic bullet. A residual insecticide is necessary. Control of a bed bug infestation typically takes several treatments. It is important to use several different formulations, and often, several different insecticides. Dont keep using the same insecticide (rotate insecticide use) </li> <li> Slide 57 </li> <li> Active Ingredient (insecticide class) Product Name(s) Imidacloprid + -cyfluthrin (neonicotinoid + pyrethroid) Temprid SC Chlorfenapyr (halogenated pyrrole) Phantom SC Phantom PI Acetamiprid + bifenthrin (neonicotinoid + pyrethroid) Transport Mikron Transport GHP Thiamethoxam + -cyhalothrin (neonicotinoid + pyrethroid) Tandem Dinotefuran + diatomaceous earth (neonicotinoid + silica dioxide) Prescription Treatment Alpine Dust Alpine PI Non-pyrethroid Insecticides For Use Against Bed Bugs </li> <li> Slide 58 </li> <li> Active Ingredient Product Name Miscellaneous Label Notes Diatomaceous earth (=silica dioxide) Natural Guard Crawling Insect Control Safer Brand Ant &amp; Crawling Insect Killer - Crack &amp; crevice applications - Slow-acting - Residual (long-lasting) activity - Dusts should be applied in thin layers - DO NOT allow product to get wet or it will permanently lose effectiveness - Caution: Avoid inhalation; wear a dust mask during application - Pool grade DE should NEVER be used for pest control. Pool grade DE contains crystalline silica and can be a respiratory hazard. - Mattresses mentioned on label Phenothrin w/isopropanol with synergist Steri-fab Bedlam -Steri-fab: General surface application -Bedlam: Mattresses mentioned on labelemphasis on seams, tufts and folds; spot applic. elsewhere -Contact insecticide, not a residual Some Insecticides Registered For Use Against Bed Bugs </li> <li> Slide 59 </li> <li> Responding to a Bed Bug Incident at School Obtain samples of the insect for positive ID Arrange for professional inspection ASAP Try to determine who has bed bug infestations at home so that you can offer guidance and suggestions: Provide educational material on bed bugs Communicate the importance of eliminating the bed bug infestation at home Suggest limiting the number of items brought to school Suggest storing school items inside a sealed container away from beds and upholstered furniture at home Reference: L.

Sleep tight, and dont let the well, you know the rest </li> <li> Slide 64 </li> <li> BED BUG PREVENTION FOR TRAVELERS Make it STANDARD PRACTICE to check for bed bugs in hotel/motel rooms! Pull back the bedding and look for black fecal spots on mattress &amp; box springs (especially seams) Carefully examine the underside of the bed skirt Look for bb signs along bed frame (especially head board) Open nightstand drawers and look for bb signs along inner and outer edges Look for bb signs along baseboards DONT STAY IN A ROOM THAT HAS BB SIGNS </li> <li> Slide 65 </li> <li> BED BUG PREVENTION FOR TRAVELERS Keep clothes in your zipped suitcase Dont keep clothes in hotel chest-of-drawers OK to hang clothes in closet Dont store your suitcase on the bed, floor, or upholstered furniture Keep your suitcase on the luggage rack (after first inspecting it for bb signs) Reduce the chances of getting bed bugs from hotel/motel rooms! The bathroom (tub) is the best place to store your items! </li> </ul>
