Flies From Dead Rats, Mice & Squirrels

Flies are the common cleaners of dead rodents that have died in your property so in the beginning, should never be viewed as a nuisance.

Avoiding The Cycle Of BAIT - STINK - FLIES - REPEAT

Dead rodents are an experience to behold! The smell is strong, acrid and unmistakeable. Anyone reading this might be doing so because the smell is already permeating your home and wish to discover what they can do about it.

We have to look at this in stages, but before we do that, here are the rules of stink free rat and rodent control!

Fly Free Rule Number One

Always use single-feed poisons where safe to do so. Why? Because single-feed poisons cause the rodent to lose fluid volume quickly.

As the rodent loses fluid volume (blood or plasma), it will have an unquenchable thirst driving it to water where it will likely die outside your home.

Where Will The Rat Die?

The poisoned rat will head to what it knows to be a reliable water source. In 90% of cases, this will usually be the drain fault where the rat entered the fabric of your property. These rats often die in the sewer and get washed away without a trace.

In the event of poisoned squirrels or mice, it's more likely that water in partially blocked gutters will provide refreshment for the final time. These rodents die outside the property and can commonly be found directly below the gutters from which they have fallen.

Remember we said "Single Feed Poison"! So what happens if you use multi-feed poison instead?

Imagine this scenario. Single feed poison is designed, or at least it's marketed to do exactly what it says on the tin or tub. A single feed should prove to be fatal.

The problem for amateurs is that single-feed poisons are likely labelled and distributed for "professional use only". The most common baits left for amateur use are multi-feed, and here's the rub.

Multi-feed poisons will cause death after two or more feeds. Meaning your rodent gets sicker and sicker until it eventually dies. This slower and gradual decline in mobility and coordination is likely to result in a rodent that's unable to get itself to water and is more liable to die in the fabric of the property!

Fly Free Rule Number Two

Don't carry out any proofing or remediation for at least seven days after poisons have been deployed.

The reason is related to rule number one. You need to give poisoned rodents a chance to leave your property. If you block up all the entry points right away, where else can they die?

Proofing points of entry too early can be a dumb thing to do.

Fly Free Rule Number Three

Once all potential entry points are sealed, consider moving over to lethal trapping.

Just for the record - humane trap and release of vermin is illegal for professionals, and no one is going to thank for releasing rodents in their back yard. If you decide to release them in your garden, the rodents will almost always try to get back in!

How Get Rid Of A Dead Rat Smell?

We use professional deodorising products, but in general, you are just replacing one bad smell with another stronger smell.

Venting out rooms by opening windows and doors can usually get rid of smells that have developed over many hours or days in just a few minutes.

Plug-in air fresheners are an excellent way of combatting smells and work very well in most situations.

What Happens To Rodents That Die In Your Property?

If you are unlucky and a rodent dies in your home, the very first thing you will notice is the smell.

Once the animal dies, the body goes into biological or cellular death. As the body begins to break down, gases produced cause the rodent to bloat and sometimes burst.

The gases usually vent from the mouth and anus, attracting the large metallic flies we know as blue bottles, green bottles and meat flies. This process is temperature related - the warmer it is, the faster it is.

If the rat dies on a cold day in January, that could be very bad news! Not only could the decomposition process be prolonged because of low temperatures, but also because very few flies are around in the winter months. This could mean a prolonged smell of a month or more.

If a rat dies on a hot day in July in an area where flies can enter freely through air vents in bricks or roofs, then the smell could last no more than a few days.

The flies lay their eggs around the mouth, ears, nose, eyes, etc. as the larvae hatch they move inside the body, eating it from the inside out leaving only the skin, fur and bone.

Over the next year, beetle and moth larvae will likely consume what the fly larvae leave behind.

The fly larvae eventually exit the carcas and crawl off into the surrounding structure to pupate. Sometimes these larvae fall from gutters, or through light fittings and wall vents - yes we see it all.

Within 14 days the adult flies emerge. The first few days will bring a few flies, followed by a swarm of hundreds of flies. These swarms are very short lived and within several days only a few flies a day will be appearing. These random flies can continue emerging for many weeks after the primary swarm or mass emergence.

How Do You Get Rid Of The Flies?

We recommend turning off all lights during the day to draw them to windows where they can be brushed out of open windows.

Vacuums are the next best method of control along with fly spray.

The alternative is professional fumigations, and you might need a few of these, because fumigants are not residual, and the flies won't all hatch together.

Do The Flies Carry Disease?

Newly hatched flies are unlikely to be carrying significant pathogens, but should still be considered high risk.

More About The Types Of Flies Found In The Home

Bristol Fly Control: The flies that interest us, are called the "true flies" from the order Diptera and are small insects that are responsible for removing and recycling huge quantities of waste both animal and plant in origin.

There are estimated to be over 100,000 different species yet only a small proportion are considered important pests both as a nuisance and as vectors of disease.

Blow Flies:

Large Green and Blue Metallic Flies. Associated with Dead Rats, Etc.

Blow flies (family: Calliphoridae) are among the most recognisable flies of this group found in Bristol and this due to their amazing metallic colours. Blue bottle and Green bottle flies in particular are very distinctive and recognisable to most people.

They feed on carrion and decaying organic matter and can often be seen on flowers where they consume carbohydrate rich nectar.

Cluster Flies:

Large Numbers of Flies Overwinter In Lofts and Attics. Not considered a health risk.

Cluster Flies make up a large number of flies, found in properties during the colder months of the year, hibernating in loft spaces in clusters that can number many thousands. 2013 was definitely the year of the Cluster Fly, so every year one fly species will do better than others.

House Flies:

Nuisance Flies in Homes, Kitchens and Food Prep Areas. Considered a major health risk.

House Flies are as the name suggests among the most common flies to be found in our homes and represent a significant hazard to food safety.

Horse Flies:

Large Biting Flies with large, often Metallic Eyes. A biting, nuisance fly causing deep skin infections

Horse Flies are the tigers of the sky and are among the very largest flies found in the United Kingdom. 2014 has been a very good year to be a horse fly as populations in July were way above average in many Bristol areas. Horse Flies are large, fast and many, despite being very large are silent in flight. The horse flies bite however is anything but discrete.

Fruit Flies:

Small, Nuisance Flies Flies with Orange Eyes. Seen as an indicator of poor hygiene.

Fruit Flies are very small flies found on rotting organic matter especially fruit. Now becoming far more common as a nuisance pest since the rise of mandatory recycling programmes requiring a brown food waste box, often kept on counter tops.

Before you do anything you need to identify where the flies might be coming from and what species they are.
