Pest Group 010: Adult Mosquito Surveillance

Equipment Provider: The Contractor shall provide the mosquito light trap(s) and all other equipment (as needed) to complete mosquito survey(s) as directed by the KO. All cost for procurement of equipment (including traps, batteries, extension cords, light bulbs, collection bags, etc.) shall be included in the bid price for this service and does not constitute grounds for any added charge under any other part of this contract.

Trap Design: Type of trap will be determined by the target mosquito species. The installation Preventive Medicine Department can provide information on local nuisance and vector mosquitoes. New Jersey light traps (or equal), CDC Miniature light traps (or equal) (battery operated), gravid traps, or other commercially purchased light trap designs deemed acceptable to the Armed Forces Pest Control Board (AFPMB), shall be used. The Government may or may not provide electricity at the site where the KO designates that the light traps shall be placed. If no electricity is available, battery operated units shall be used. Battery operated units may be used even if electricity is provided. The government shall not supply batteries. Use the same trap design at the same location throughout the course of this contract.

Trap Placement: Traps shall be placed so as to effectively collect and measure the target mosquito population. The Government may determine trap locations.

Trapping Frequency: Traps shall be set each week (weather permitting). If weather is inappropriate for trapping (heavy rain or consistent winds above 15 MPH), perform trapping on the night following the scheduled night (or the next appropriate night). Conduct adult mosquito trapping in accordance with the weekly schedule.

Survey Data: At a minimum, the Contractor shall count the total number of mosquitoes in the trap and record the number on the Adult Mosquito Catch Form.

Disposition of Mosquitoes: Consult with the installation Preventive Medicine Department to determine if mosquito collections should be saved for identification and testing. If the mosquitoes are to be retained then the following method should be used. Immobilize and kill mosquitoes and other arthropods by placing in the trap container in a freezer or using another suitable method that does not destroy the specimens (e.g. do not immerse in alcohol). (Mosquitoes collected for testing (e.g. West Nile Virus) may require specific handling; consult with the Preventive Medicine Department.) Place trap contents in a paper or cardboard container and label with time, date, location collector’s name and contact information. Deliver to personnel designated by the KO to receive the mosquito trap collection. If mosquitoes do not need to be kept, then they should be disposed.

Reporting Adult Mosquito Collections: The Contractor shall complete the number of samples designated by the Government and record (in legible handwriting) the results of the survey for each location sampled. The Contractor shall note the date and time of collection, the number of mosquitoes collected per sample site, type of breeding source, notes regarding the sampled mosquitoes, and sum or average the totals. The KO may provide a collection form (Adult Mosquito Catch Form) on which the survey results are recorded. Records shall be reported on the collection form and submitted weekly during surveillance to the KO and the installation Preventive Medicine Department.

ATTACHMENT J-1503020-07

Pest Group 016: Larval Mosquito Surveillance

Equipment: The Contractor shall provide all equipment (as needed), to complete the assigned task(s) including , but not limited to, ladders, asepto syringes, boots, dippers, notebooks, etc (as applicable). The Contractor shall sample for immature mosquitoes on the schedule designated by the KO.

Survey Designated Mosquito Breeding Sites (Areas designated by the ACO or Contract Specifications): Areas shall be designated by the KO for IQ work, and by maps for FFP work. In the designated area(s), there may be differing aquatic environments to sample from including but not limited to, wetlands, standing pools of water, tree holes, artificial containers, clogged rain gutters, land depressions with temporary pools, floodwater plains, standing ponds, underground or aboveground storm water catch basins, swamps, drainage ditches, tire dumps, recycling areas, or any area where mosquitoes can breed. It is the responsibility of the Contractor to survey all potential mosquito breeding sites within the designated area(s).

Previous Experience: Larval mosquito surveys are very technique sensitive. Only Contractor personnel, with significant previous experience sampling for immature mosquitoes, shall perform larval surveys.

Survey Techniques:

In larger bodies of water such as ponds, lakes, catch water basins, etc., perform surveys around the water perimeter using a standard larval mosquito dipper (style and type approved by the Installation Preventive Medicine Department and the KO). Complete a sufficient number of dips to develop an accurate average dip count for the body of water (e.g. 10 dips/sampling station). Different species of mosquito larvae must be surveyed using different dipping techniques. It may be necessary to proceed carefully, or to act swiftly depending on the species being sampled, as water disturbance or casting shadows could result in the larvae diving to the bottom. It is the Contractor’s responsibility to know the proper sampling technique(s) for the mosquito species present.

In smaller water bodies such as rain gutters, artificial containers, tree holes etc., samples shall be taken using an appropriate collection device.

Reporting Larval Mosquito Collections: The Contractor shall record (in legible handwriting) the results of the survey for each location sampled. The Contractor shall complete the number of samples designated by the KO for each location. The Contractor shall note the date and time of collection, the number of immature mosquitoes collected per sample site, type of breeding source, notes regarding the sampled mosquitoes, and sum or average the totals. The KO may provide a collection form on which the survey results are recorded. Records shall be reported on the collection form and submitted every two weeks during surveillance to the KO and the installation Preventive Medicine Department.

A detailed written structural assessment shall be made by the Contractor with concurrence by the Contracting Officer prior to initial treatment for reference at a later date, should there be any questions of subsequent damage. The limit of the Contractor's liability for repairs is $25,000 per building.

(2) Drywood Termite Control. Provide drywood termite control as described below.

The presence of an inspector trained in fumigation is essential while fumigant concentration readings are taken to determine that all drywood termites are killed during fumigation. Adherence to proper procedures must be assured while the work is being accomplished.

(a) Safety Measures. The Contractor shall ensure proper techniques and procedures are followed. Precautions shall be taken to prevent injury to any person and damage to property as a result of work accomplished under this section. These precautions shall include, but are not limited to, the following:

1. Safety Equipment. Before releasing any gas, the Contractor shall deliver to the KO, ready for use by Government personnel, two full-face gas masks, each with two new, unused canisters appropriate for the gas to be employed, or a similar number of self-contained breathing apparatuses, each with a cylinder of air; a completely stocked and illustrated fumigator's first aid kit (all meeting specifications of the Health and Safety Division, Bureau of Mines, U.S. Department of the Interior); and at least one approved low-volume gas detector for the fumigant to be employed. All such equipment will be held at the site until completion of the work.

2. Notification of Security Officer. The activity Security Officer shall be notified at least 24 hours prior to the commencement of fumigation operations, and upon completion of the work that the building is being left unattended.

3. Disconnection of Services. Prior to fumigation, all gas and other fuel supplies shall be cut off. Electric and telephone service need not be disconnected; however, the electric main entrance switch shall be pulled. All fires, including pilot lights, shall be extinguished prior to beginning fumigation procedures. After fumigation and subsequent ventilation has been completed, electric power, pilot lights, etc., shall be turned on or relit. Damage to any service caused by the Contractor shall be repaired at no additional cost to the Government.

4. Barricades. A double rope barricade shall be placed no closer than 20 feet to, and around the entire perimeter of the building to be fumigated. Existing fences may substitute for rope barricades if they are at least 20 feet from the building.

5. Signs. Warning signs shall be placed prominently on all means of ingress to the building and grounds, including fences and rope barricades surrounding the work. Signs shall include a statement that the building is being fumigated with sulfuryl fluoride or the name of another fumigant gas. Signs shall not be less than 18 by 24 inches in size and shall meet all state and local wording requirements.

ATTACHMENT J-1503020-07

6. Guards. At least two guards shall be placed around the building before gas is released. Guards shall be positioned at either end of the structure so the maximum amount of the building is under continuous observation. Guards, warning signs, and barricades shall be maintained during the entire fumigation process until the Contractor has checked for gas concentration and declares the entire area gas free and safe for normal occupancy.

7. Lighting. The Contractor shall provide adequate lighting around the exterior of the structure being fumigated to permit ready detection of trespassers during the night.

8. Evacuation of Personnel. After all persons and animals are evacuated from within and under the building, guards are posted, and prior to release of the fumigant, the Contractor and KO shall jointly inspect all rooms and spaces to assure evacuation is complete.

9. Partial Fumigation. No partial fumigation of any building shall be allowed.

(b) Preparation.

1. Grass and Shrubbery. Wet the soil in planted areas to a depth of six inches for a distance of one foot outward from the areas to be covered by the tarp, to protect nearby plant roots from injury. In this respect, the Contractor shall exercise every precaution to protect and preserve grass and shrubbery that may come into contact with the building. Any plants, shrubs, or grass damaged by the gas or otherwise, shall be replaced at no additional cost to the Government.

2. Sampling. Furnish and install a minimum of four polyethylene tubes leading from approved locations within the structure to an approved location outside for the purpose of recording gas concentrations. Also furnish for use and have available during the entire fumigation period an approved thermal conductivity gas metering device, correctly calibrated in ounces per 1,000 cubic feet for the fumigant to be employed, and capable of sampling from the polyethylene tubes.

3. Removal of Damageable Items. Remove all items from the building that might be damaged by the fumigant and maintain in locked storage. Lost or damaged items shall be repaired or replaced by the Contractor at no additional cost to the Government.

4. Building Proper. In preparing the building for fumigation, exterior doors and windows and all entrances to enclosed interior areas, such as doors or windows leading to closets or cabinets or between rooms, shall be opened to facilitate distribution of the gas during fumigation and insure maximum ventilation at the end of the fumigation period.

(c) Procedure.

1. General. The building to be fumigated shall be completely enclosed with a gas-impervious tarpaulin material, with all sheeting seams securely sealed, and the lower edges of the enveloping cover sealed to the ground or finish grade level in a trench, with moist soil or with sand/water snakes (flexible tubing filled with water).

ATTACHMENT J-1503020-07

2. Introduction of Chloropicrin. After preparation and sealing of the structure (except for one entrance) and prior to injection of the sulfuryl fluoride (Vikane), the Contractor shall introduce chloropicrin into the structure. The chloropicrin shall be introduced by placing cotton in shallow dishes, setting the dishes in the air stream of an electric fan within the structure, and pouring the chloropicrin over the cotton at the rate of one ounce per 10,000 to 15,000 cubic feet of space to be fumigated. The building will then be sealed and the fans started.

3. Fumigation. After introduction of the chloropicrin, the fumigant described below shall be released from cylinders placed outside the enclosed areas through not less than two hoses of either rubber, polyethylene tubing, or copper tubing leading to points well distributed within each floor of the building as previously approved by the KO. The liquid shall be injected at a temperature and pressure to guarantee complete vaporization upon its release. Sufficient air turbulence shall be created to maintain uniform distribution of the fumigants throughout all portions of the building and to prevent stratification of gas at any location by use of not less than four electric fans, each having a capacity of 3,000 to 5,000 cubic feet per minute (CFM).

4. Fumigant and Dosage Rates. The fumigant shall be sulfuryl fluoride (Vikane) gas, injected in vapor form, and maintained in accordance with Dow Chemical Company Fumiguides B and Y. When the whole Fumiguide calculated initial concentration is obtained from all sampling points, the 24-hour fumigation time period starts. If the Contractor wishes to increase dosage rates to shorten the fumigation time in accordance with Fumiguide Y, prior approval of the KO and the NAVFAC PPMC is required.

5. Borate Treatment. In addition to the aforementioned treatment, a glycol borate solution of Bora-CareTM shall be applied in attic and crawl spaces of the building. Apply a one-part water to one-part Bora-CareTM solution to the point of run off (one gallon of diluted solution for each 500 feet of surface area) to all exposed wood surfaces. Follow all labeled directions for the safe handling and use of this product. Aerosol application will be allowed only in inaccessible areas and with the prior approval of the KO.

6. Sampling. During the actual 24-hour fumigation period, the gas-laden atmosphere within the enveloped structure shall be sampled from each sampling point five times: at the inception, and at four, eight, 16, and 24 hours after inception. The Contractor shall take appropriate action to ensure proper distribution of the gas and maintenance of the level of concentration specified. Sample readings shall be recorded and a copy of the readings provided to the KO upon completion of the treatment.

(d) Aeration. Upon termination of the fumigation exposure period, the Contractor shall remove all seals, open all doors and windows, and use ventilation fans to remove fumigants from dead air pockets with full observance of accepted safety, state, and labeled aeration procedures to avoid exposure of any persons or other life to dangerous concentrations of fumigant gas. The Contractor shall check for complete aeration with a low-volume gas detector in all enclosures, which might retain concentrations of gas, such as closets, cabinets, refrigerators, and chests, and certify to the KO that the structure is gas free and available for occupancy.

(e) Clean Up. Upon completion of the fumigation, remove all debris and rubbish resulting from the work, replace damageable items removed from the building, and repair all damage resulting from the work.

ATTACHMENT J-1503020-07

(f) Warranty. The Contractor shall guarantee the fumigated building is completely free of living drywood termites for one year after the fumigation is completed. The Contractor, accompanied by the KO, shall make two thorough inspections of the structure, at six-month intervals, following the fumigation date. The written findings of each inspection shall be provided to the KO within 10 working days after inspection completion. Positive evidence of drywood termite infestation, except from furniture and other moveable property installed during the one-year period, shall constitute conclusive evidence of improper fumigation and lack of control, and the building shall be refumigated at no additional cost to the Government.
