ohioline.osu.edu/hyg-fact/2000/2067A.htmlThese insects like to live in very moist areas with plenty of decaying organic matter present for food. This includes areas such as flowerbeds, excessive grass clippings, compost areas, under trash, and rotting firewood stacked on the ground. They make their way indoors if chased from their normal harborage area due to flooding, excessive drought in the summer, or normal migratory mating habits in the fall. Once out of their normal harborage area they will die of dehydration very shortly usually into a spiral shape. They are nocturnal and will migrate toward structures in extremely large numbers. This usually occurs in the early fall.
Control is a multi step process. Try to remove as much excess leaf, wood, or other type debris to minimize harborage sites. Repair any gaps, cracks, or holes on the exterior of the structure to minimize entryways and harborage sites. Replace any worn, loose, or missing weather stripping around doors and windows. Also check for any worn doorway threshold areas and repair or replace as needed. It might be useful to check the exterior lighting and if necessary, change to yellow or sodium vapor bulbs that don’t attract insects as easily. Lawn modifications to minimize excessive moisture may also be necessary to gain control. These include detaching the lawn to minimize grass from holding excessive moisture. Mow and trim the lawn on a regular basis to keep the lawn from retaining excessive water. By watering lawns in the morning, this allows the lawn to dry through the day so it won’t hold water for such a long period of time. This may also help cut down on some types of lawn diseases. If you have a crawl space
make sure there is adequate ventilation so excessive moisture does not accumulate.
For quick control of the ones you see use an aerosol product. They come in both contact and residual types. Residual products leave behind material to remain active for a further length of time. Residual products include items such as
Cy-Kick 17.5 oz. can,
Invader HPX 14 oz. can, and
D-Force HPX 14 oz. can. Contact products include items such as
PI 18 oz. can,
PT 565 Plus 20 oz. can,
CB 80 Extra 17oz.can.
Liquid residual concentrates are mixed with water at label rates as needed. This method gets the treated area to a “neutral” condition where no insects or spiders are present. The drawback is that after 2 or 3 sprinkler cycles, a rain, or heavy dew the material is diluted to the point of ineffectiveness and nothing is there to provide continued control. If you use this method to control millipedes and other insects at the same time, a couple of weeks later you may want to treat with a weather resistant particle bait such as Niban to provide continued control for pests other than millipedes. Residual concentrate products include
Demand CS 8 oz. or
Demand CS 1 qt.,
Suspend SC 1 pt.,
Tempo SC 240 ml,
Tempo Ultra WP 420 gram btl,
Talstar Pro 1 pt. or
Talstar Pro ¾ gal,
Viper 4 oz.,
Demon WP 4-9.5 gram bags per pk,
Demon WP 1 lb. jar,
Demon EC 1 pt.,
Cy-Kick CS 1 pt. or
Cy-Kick CS 120 oz.. These materials can be applied with a
1 gal. Poly Sprayer or a
2 gal. Poly Sprayer. For foundation perimeter application or yard application use a
Gilmour Hose End Sprayer Model 486 or a
Gilmour Hose End Sprayer Model 362. A lot of these products are labeled for inside use as well.
Viper RTU is a ready to use pre mixed product in a 1 gal. Container with a handy sprayer attached to a 1-foot hose.
Before applying the liquid residual around the foundation perimeter apply insecticide dust in the weep holes and other void areas such as gaps, cracks, holes or other areas along the outside to control millipedes running to these areas in escape of the liquid treatments. These products include
Delta Dust 1 lb. btl,
Delta Dust 5 lb. btl,
Borid 1 lb. btl, or
Borid 5lb. btl. The insecticide dust is best applied with a
Crusader Hand Duster. The dust works by applying a light amount in the target area. The pest then walks across it, picks it up on their body and ingests the dust as they groom themselves. The dust is a stomach poison and control is completed in this manner. If you use too much, they will avoid the area.
Copper mesh applied in the weep holes is a good way to minimize insect and spider entryways into this area. Since it is made of copper it won’t leave streaks down the foundation and the mesh is wide enough to allow adequate ventilation behind the bricks. This includes products such as
Stuff-fit Copper Mesh 20 ft. roll,
Stuf-fit Copper Mesh 20 ft. Precut, and
Stuf-fit Copper Mesh 100 ft. Roll.
Use these Niban products for the foundation grass line, landscape areas, and/or yard areas. This is a good material to treat pests other than millipedes that are in the same area such as ants, roaches, crickets, and earwigs. These sizes are more suited to outside applications
Niban Insect Bait 5 lb. Shaker Bag, or
Niban Insect Bait 40 lb. Bag. These particle baits are best applied with a
14 oz. Centro Bulb Duster. We carry a handy
Bulb Duster Filler Funnel that makes it easier to fill from the larger size containers. The bottom of the funnel is the same size as the top of the bulb duster. Remember the particles are weather resistant through up to 4 inches of water. This bait works well through sprinkler cycles, rain, or heavy dew.
Another control method is insecticide granules. These materials include
Talstar PL 25 lb bag and
Delta Gard 20 lb. bag. These products are applied with a hand spreader such as a
Scotts Handy Green 2 Hand Spreader. These materials work well when applied and even better when watered in. They are applied at the foundation perimeter and yard areas.
Glueboards are a good tool to use because they serve to control the insects and monitor for activity. If any are found observe which way the pest is captured. This will allow you to backtrack to find possible harborage areas or entryways. We carry
Catchmaster CM MB 72 72 ct box,
Catchmaster CM MB 72 8 ct pk, or
Trapper LTD 72 ct box.
