How Much Does Spider Control Cost in Greenwich?

Start Here: You Probably Do Not Need This

Every September the phone starts ringing about spiders, and almost every one of those calls has the same explanation. Mature male house spiders leave their webs in late summer and early autumn to look for females. That is why large spiders suddenly start crossing floors and getting stuck in baths.

It lasts a matter of weeks. It happens in every house in the country. British house spiders are not dangerous, they do not damage the building, and they eat a considerable number of the insects that would otherwise be in the room with you.

Paying £180 for that would be paying us to interfere with a seasonal event that stops on its own. A glass and a piece of card is the correct treatment. We would rather say that on the phone than take the booking, and we do.

When It Is a Fair Spend

There are real situations, and they have a shape in common: a large or partly unused space, persistent webbing, and a reason it matters.

• Commercial premises where webbing is an operational problem. Warehousing, storage, workshops, food premises and hospitality frontage have standards to meet. Heavy webbing across a stock run or a shopfront is a hygiene, presentation or audit issue rather than a matter of taste. This is where most of the spider work that genuinely needs doing sits.
• Cellars, semi-basements, garages and outbuildings. These support a far larger population than a living room, and webbing that returns within days of clearing is a different matter from a spider in the bath.
• A genuine and persistent phobia. Where a treated, sealed and web-free property makes a real difference to somebody's ability to use their own home, that is a legitimate reason and we do not treat it as a trivial one.
• Confirmed noble false widow activity in a living area, where the identification has been checked and the activity is persistent rather than a single sighting.

About the False Widow, in Both Directions

The noble false widow is established across southern England and does turn up in London property. It is worth being straightforward about it rather than either dismissing it or selling it.

It is the British spider most likely to give a bite worth mentioning, and bites do happen - usually when one is trapped against skin in clothing or bedding. It is also nothing like the animal the headlines describe: bites are uncommon and most reported ones amount to a local reaction comparable to a wasp sting.

It is also very frequently misidentified. A great many photographs sent to us as false widows turn out to be ordinary house spiders or cellar spiders. Send a clear picture before booking anything - it costs nothing and it is the cheapest step in this entire process.

What the Money Buys, Where It Is Warranted

Not chasing individual spiders. The work is about webbing and harbourage:

1. Existing webs and egg sacs are removed. Leaving them means the population re-establishes from where it already is, which is why web removal comes first rather than last.
2. A residual treatment goes to the harbourage points and the runs between them - frame edges, ceiling junctions, roof voids, cellar structure, window reveals and external entry points.
3. Entry points and contributing conditions are identified, because those are what decide whether the result lasts.

The Limitation, Stated Plainly

No treatment makes a building permanently spider-free, and anyone telling you otherwise is overselling. Spiders come in from outside through the same gaps everything else uses. Treatment plus web removal reduces the population; reducing the insects they feed on, closing entry points and keeping webbing cleared is what keeps it down.

For commercial premises that usually means a planned programme rather than a one-off, and it is worth pricing it that way from the start.

How a Commercial Programme Is Scoped

For business premises - which is where most genuine spider work sits - a one-off treatment is usually the wrong shape. Here is how a programme is put together, so you can compare it with anything else you are quoted.

1. The areas are defined, not the building. A stock run, a loading bay, a production space and a customer-facing frontage have different standards and different intervals. Pricing the whole building as one unit usually means overcharging for the parts that do not need it.
2. Web removal is scheduled separately from treatment. Removal is what produces the visible result and it needs doing more often; residual treatment goes to harbourage and needs doing less often.
3. The lighting and the insect load get looked at. Spiders follow the insects, and the insects follow the light. Changing what is lit at night is frequently the cheapest intervention available and it belongs in the plan.
4. The interval is set by how fast webbing returns, measured rather than assumed - which means the first period is a trial and the schedule is set afterwards.

Tell us the size and type of the premises and the areas involved, and we will confirm what fits before anything is committed.
