Emergency Pest Control: What to Do Right Now

A wasp nest above your back door. Rats scratching in the walls with young children in the house. Bed bug bites appearing overnight. Some pest situations feel urgent — and some genuinely are. This guide covers exactly what to do right now, how to tell whether you need same-day help or can safely wait, and what an emergency call-out actually involves.

Immediate Steps: Wasp Nests

If you've discovered a wasp nest on your property, here's what to do straight away:

1. Keep your distance. Stay at least 3 metres from the nest and keep children and pets away. Wasps become aggressive when they perceive a threat to the nest, and an agitated colony can attack in large numbers.
2. Do not attempt to remove it yourself. Do not spray it with water, hit it with a stick, or try to knock it down. Shop-bought wasp foam sprays are unreliable and put you within striking distance of the nest. Every summer, A&E departments across the UK see patients who attempted DIY nest removal.
3. Close nearby windows and doors. If the nest is near an entry point to your house, keep it closed to prevent wasps coming inside.
4. Avoid wearing strong perfume or aftershave near the nest area, and don't eat or drink sweet things outside — both attract wasps.
5. Call a pest controller. Wasp nest treatment costs £50–£100 and takes about 30 minutes. Most companies can attend the same day or next day during wasp season (June–September).

Is it truly urgent? If the nest is in a location where people regularly pass — above a doorway, in a garden where children play, near a seating area — treat it as urgent and book same-day treatment. If it's in an unused corner of the garden or high up on a wall away from foot traffic, it can safely wait a day or two.

Immediate Steps: Rats and Mice

If you've found evidence of rodents in your home, take these steps immediately:

1. Secure all food. Move any food that isn't in tins or glass jars into airtight containers or the fridge. This includes pet food, bird seed, and anything stored in cupboards at floor level. Rats and mice can gnaw through plastic bags and thin cardboard.
2. Clean up droppings carefully. Wear rubber gloves and use damp kitchen roll to pick up droppings — don't sweep or vacuum them, as this can spread bacteria into the air. Dispose of the droppings in a sealed bag and disinfect the area with a bleach solution.
3. Block obvious entry points temporarily. Stuff steel wool or wire mesh into any gaps you can see around pipes, under doors, or where cables enter the house. Mice can squeeze through a gap the diameter of a pencil; rats need about 25mm.
4. Don't use shop-bought poison if you have children, pets, or suspect the rodents are in your loft (where a poisoned rat may die in an inaccessible location and create an appalling smell for weeks).

Is it truly urgent? Rats in a home with young children or vulnerable adults should be treated as urgent. Rat urine and droppings carry leptospirosis (Weil's disease) and salmonella. Gnawed electrical wiring is a fire hazard. A single mouse with no children in the house is less urgent — you can try DIY traps first and call a professional if they don't work within a week.

Immediate Steps: Bed Bugs

Discovering bed bugs is distressing, but the good news is they don't move quickly between rooms and they don't fly. Here's what to do right now:

1. Don't move to another bedroom. This is counterintuitive, but sleeping in a different room encourages the bugs to follow you (they're attracted to body heat and CO2), spreading the infestation to new rooms.
2. Strip the bed. Put all bedding, pillowcases, and any nearby soft items (pyjamas, cushion covers) in plastic bags and wash at 60°C. The heat kills bugs and eggs.
3. Inspect the mattress. Check the seams, piping, and any folds or tufts for live bugs, shed skins, and dark faecal spots. Also check the bed frame joints, headboard, and bedside furniture.
4. Do not spray shop-bought insecticide. Over-the-counter sprays kill bugs on contact but have no residual effect, and can scatter bugs to new hiding spots, making professional treatment harder.
5. Call a professional. Bed bugs require specialist treatment with residual insecticides applied over 2–3 visits. The sooner you start, the fewer rooms need treating and the lower the cost.

Is it truly urgent? Bed bugs are not dangerous — they don't transmit disease. But they won't go away on their own, and every night you wait means more eggs being laid (each female lays 2–5 eggs per day). Aim to have a professional booked within a few days of discovery, but you don't need a same-day emergency call-out.

When It's Truly an Emergency

A genuine pest emergency is a situation that poses an immediate risk to health or safety. These situations warrant same-day or next-day treatment:

• A wasp nest near a doorway or window that you or your family must use regularly, especially if anyone in the household has a known wasp allergy.
• Rats inside the living space (not just the loft or garden), particularly in homes with young children, elderly residents, or anyone with a compromised immune system.
• Rodent damage to electrical wiring, which creates an immediate fire risk.
• Any pest infestation in a food preparation area of a business (cafe, restaurant, nursery) — this is a legal obligation under food safety regulations.

When It Can Wait

These situations are unpleasant but not dangerous. Booking a professional for the next available slot (usually within 1–3 days) is fine:

• Ants in the kitchen (try DIY bait stations first)
• A wasp nest in an unused area of the garden, away from foot traffic
• Mice in the loft with no signs of entry into the living space
• Bed bugs (distressing but not a health hazard)
• Moths in a wardrobe or pantry
• Fleas (treat pets immediately, but the house treatment can wait a day or two)

What to Expect From an Emergency Call-Out

If you book an emergency or same-day pest control visit, here's the typical process:

1. Phone assessment. The company will ask what pest you're dealing with, where in the property it is, how severe the problem appears, and whether anyone in the household is at particular risk (allergies, young children, vulnerable adults). This helps them bring the right equipment.
2. On-site survey. The technician will inspect the affected area, identify the pest species, assess the extent of the infestation, and explain the treatment plan. This usually takes 10–20 minutes.
3. Treatment. For wasps, this is a single application of insecticidal dust or spray (20–30 minutes). For rodents, bait stations are placed and entry points assessed (30–45 minutes). For insects like cockroaches, gel bait or spray is applied to harbourage areas.
4. Follow-up. Most treatments (except wasp nests) require at least one follow-up visit, typically 1–2 weeks later, to check bait take, replenish stations, or apply a second round of treatment. This is usually included in the quoted price.

Emergency Pricing

Same-day and out-of-hours call-outs carry a premium over standard bookings. Expect to pay an additional £30–£80 on top of the standard treatment price. Weekend and bank holiday call-outs are at the higher end. If the situation can wait until a weekday, you'll save money by booking a standard appointment — but if there's a genuine safety risk, don't delay.
