Thank you for the document.

In our company, we have a problem regarding pest control. We have the pest and Rodent control system in place.

For pests- Cyfluthrin 0.05% every week sprayed and we have insect screens on windows, strip curtains and air curtains on doors. We check the trend with flycathers

For Rodents- Rat n box outside the production unit with bromodiolon cakes checked every 2 days. Glue pads in stores inside checked every 2 days

But still we cant control the pests and rodents. Rats are still inside the production unit.

Trend analysis shows good reduction in the number of pests but we still can find flies and ants inside the production unit. What can be the solution for this problem? Can we spray pesticides often or change the pesticide used?

Thank you for helping me

Dear pragash.ramadass,

Regarding rats, it may well be that there is a community established within yr plant. If so, I would suggest visually inspecting for -

(1) Any rooms or areas rarely entered, especially if due to accumulated "junk" like unused equipment.
(2) Any old stockpiles of packaging, ingredients.
(3) Unseen areas like access spaces above false ceilings, rats are good climbers IMEX.
(4) Processing Units close to areas of observed activity.

There are many other possibilities, it's really a job for the professionals.

Um, yeah, I agree this might be to time to call in a pro.

How is your building constructed? Most of the published standards discuss building construction that reduces entry points (seal your dock doors, keep mandoors closed, fix holes in the walls, etc). Is someone inspecting to make sure these critters can't gain access?

Regarding your glueboards, are they placed on either side of every door/access point? We've gone to the extent that basically every 50 feet along the warehouse walls there's a trap, even without a door being present. You may look to increase the amount of traps. If you can't use glueboards inside your production area, look into tincats and setup a schedule to check and empty them.

[Setanta]

Along the same thoughts as John123, do you maintain a perimeter away from the wall in storage areas? This would increase visibility and make the rodents less comfortable about moving around in your facility.

Good Luck!

I agree with Charles, John and Setanta above. Here are some further steps you can take also, if you havent already to try and get a handle on your pest control.

Thank you

We give space from walls for storage and also for equipments. We can inspect the pests and rodents in warehouses. Only from the inspection we understood that we need more control on rodents

Thank you john,

We have gluepads placed directly under the switch boards since rodents use the wires to enter into the warehouse. Actually the roof of the factory should be checked. Rats might have settled on the roofs. (1st floor roof- which opens to warehouse). I will work to close all openings to warehouse

You are right. They should have an established community in our factory. I will inspect each inch of the roof and all holes.

A few years ago I was inspecting an pasta supplier who had previous issues with rodents. The QM said that they replaced their perimeter of "round" river rock with crushed rock (sharp / jagged edges) and that solved their problem (for rodents coming in from the outdoors). The perimeter width was probably around 20'

[crownjohnsons]

It is important to solve perimeter problems to get rid of pests from surroundings. if we are able to control check points of these pests then our half of the pest problem is solved.

[Laura Hedley]

Thanks for the pdf jpredmore. I have download it and find a really good stuff in it. According to pragash, yes there will be any community set up by the rats in your production area because your pest controlling system is really good and effective. Instead of this rats are still in your production area which meas they have set up their community in your production area which you must inspect and find... Otherwise there will be any damage to your food quality or else

[Aggelos]

Bare in mind that if you use only glues for inside and you have big populations these will become less effective as rats will associate the glue board with danger. This is being done by some 'inspector' rats that are part of the existing families. Try some DETEX blocks which are like those you use outside but have no active substance so there is no risk of food contamination. These can be used to monitor where the infestation exists. In addition you have no problem with rats associating the block with potential danger so you can use it over and over.

Good document, anyway pragash needs and internal control of traps (daily for bait and live capture trap) and at least a weekly control made by an external.

Is good to alternate Brodifacuom and Bromadiolona every 3 months.

[Louise22]

Is it possible to include rat cages in the plant to establish a trend and then include more rodent stations on the outer perimeter of the facility and again around the building perimeter.

[austinwend]

Yeah, it is possible to implement rat or rodants cages but, the more and more you invest on the cages or something like that then the cost may rise significantly. Secondly, job done by the professional is far way better then DIY method. So, I would recommend you search for any oraganic pest control expert in your local.

the question that has not been asked is "what sort of rats/ flies/ ants"

 

Rats - if the rats are roof rats (Rattus rattus) they are likely to have entered at high level and will not be at all interested in 'bromadialone cakes' which will be cereal based and formulated against brown rat (R norvegicus)

If they are bandicoot rat, I plead ignorance as to behaviour and preferred foodstuff!

Identification of problem species and targeted treatment (including proofing and housekeeping) is key - they sound like they are in the building - zero tolerance is in order - but you need to know which species you are trying to control.

 

Flies - it is well established that flies rapidly evolve resistence to insecticides - particularly on frequent and repeated exposure to the same class of products. I strongly advise against relying on pesticides alone to control any insect, particularly flies, as their rapid breeding cycle results in the development of resistant strains. Identify your problem flies, understand what their preferred breeding medium is and clean away that breeding site at a frequency that will interupt the breeding cycle; house fly (Musca domestica) will complete a life cycle, egg to adult in 6 days at 35 C. At any temperature below that, a thorough clean once per week will prevent these flies from breeding.

 

Ants - highly sophisticated, social species - control dpends on a good identification of which ants are present. Whenever possible, bait is the best treatment - but which bait requires a species identification.

 

Good luck - get some ID!

You're exactly right, this is genius.  Well done.
