Dock Spider Pest Control & Removal

Dock spiders cause more fear due to their enormous size and their ferocious appearance. They do not cause damage to property or harm people.

We advise against attempting to remove dock spiders or detach an egg sac from a spider by hand. This significantly increases the changes that you are bitten. Attempting to use chemical and sprays around or on water to eliminate dock spiders is also advised against as this poses a serious safety risk to you and the environment.

Signs of dock spider include the remains of large exoskeletons and tent-like nursery webs in and around plants or even attached to manmade structures. Tips for helping to keep dock spiders away from your home include the following:

  • Remove piles of rock or wood debris around your home, sheds or boathouses to eliminate possible locations for shelters.

  • Keep all shoreline plants trimmed to eliminate nesting sites and possible hideouts.

  • Remove or minimizing any standing water on your property where possible.

If you think you are infested with dock spiders, or have an uncontrollable, intolerable infestation, reach out to a licensed pest control company. They have the expertise to help you safely control and treat a dock spider infestation.

Use Dock Cover Or Spider Netting

Using the same idea as with the screen, by using spider netting we are creating a physical barrier to prevent spiders and their dropping from entering your boats. The great thing about these spider netting is that they can be custom made to fit your boat, providing excellent coverage and leaving no gaps and openings for the spiders to get in.

Do Dock Spiders Bite Humans

The main food sources for these spiders are minnows, frogs, tadpoles, and water insects. Dock spiders have a pair of fangs that deliver venom to their prey causing paralysis. They are capable of delivering bee sting-level bites to humans. While this is uncommon and only happens when they are startled or threatened, it is dangerous for some people as it can cause an allergic reaction.

Do Dock Spiders Infest Homes

Pin on The Boat Galley Blog

They can make their way into your home but rarely will stay inside.

Similar to barn spiders, dock spiders cant sustain themselves inside a typical household because theres no water supply for them to hunt and theres not enough food.

They need to be outside in the pool of water skimming on the surface to hunt.

They also have huge appetites, so even the most bug-infested household isnt likely to provide them with enough insects to eat. Thus, dock spiders rarely infest homes.

Are Dock Spiders Dangerous

Normally, the first thought about these spiders is that they are dangerous due to their size, but they are not. They are very friendly insects and do not attack unless threatened or their young.

They are very protective of their eggs, especially since the mother stays alive throughout the hatching process. Proof of this is that they weave cobwebs to protect babies from any external problem.

Tips For Hiring A Marine Pest Control Service

We share a lot of lake space with our little eight-legged friends. Hundreds of spider webs can pop up overnight and give the impression of a neglected marina. While we certainly dont want to get rid of spiders altogether, it is nice to keep their presence to a minimum in and around your marina.

Hiring a marine pest control service can be viewed as a value-added service to slip renters. Boat owners will be able to spend more time on the water and youll have happy customers and a clean and well-maintained dock. Everyone wins!

Slip renters will appreciate not having to take extra time eradicating spider webs. Theyll also appreciate spending less time cleaning bug-related filth off their boats, especially since spider and other insect droppings can contain certain enzymes that actually have the ability to cause permanent damage to a boats finish and canvas.

A professional will also eliminate the need for you or slip renters to use harmful chemicals in the removal and spraying process. Many managed waterways have strict rules about what kinds of chemicals can be used on boats and docks. If you hire a professional, you dont have to worry about slip renters who may be unaware of the rules using chemicals that may be harmful to the environment.

What About Spiders In My Boathouse

Spiders in the boathouse, lake hose or cottage are common because of the presence of water.

The water supplies the necessary growth medium for a variety of aquatic wildlife and dock spiders will feed on them by attaching their body to the shore and fishing for pests.

While you cant do anything about the bugs in the water, you can prevent them from coming into your property annex.

Some tips to keep spiders out of your lake house, boathouse, cottage, or other buildings:

Keep all foliage surrounding the property clear.

You should cut and get rid of all plants you dont need because they provide nesting sites for all sorts of bugs, which will cause the insect population around the area to rise. The more bugs you have, the more spiders will come.

If you need the vegetation, then keep them trimmed and tidy.

Remove water sources. Any standing or stagnant water sources should be removed.

Standing water attracts flies, slugs, snails, beetles, mosquitoes, and more. These are all food sources for spiders. Remove all water thats backlogged and drain it.

Get rid of clutter. Spiders will need a place to hide in order to feel safe in the daytime when theyre resting.

Remove these objects and materials that they hide in so they have nowhere to go.

This may make them leave on their own or prevent them from establishing a nest in the first place.

Some of the most common places, objects, and surfaces spiders may hide in are:

Home»The Benefits Of Having a Spider Control Misting System For Your Boat Dock

Spiders are one of the messiest problems on boat docks and are extremely hard to get rid of. They can invade almost every part of your boat dock including your watercraft, boat dock, sitting areas, and outdoor living and dining areas.

Boats and personal water craft are made for fun and relaxation, but sometimes they can lead to extra work. Let our Spider Misting Systems take some of the maintenance out of owning a boat. Our spider control misting systems get you back on the water, and reduce power washings and annual dock maintenance by up to 80%!

The spider control systems use an automated misting system, just like our mosquito systems, with nozzles installed around the ceilings of your boat dock. This system will mist an Organic, EPA exempt Product that will eliminate spiders and reduce the unsightly mess they can make.

The system consists of a 55 gallon tank which acts as a reservoir, on top of which we mount a pump, motor and a control box which houses the timer and duration control. You then connect a series of nozzles using thin nylon tubing evenly spaced around ceiling and around light fixtures where spiders like to hide, thus eliminating them and their webs.

If you have a spider problem on your boat dock consider installing a DIY spider control misting kit!

How To Cure The Problem

The most radical treatment, of bombing the boat, is not necessarily the most effective. This is because the poisonous fog doesnt actually penetrate the places where the roaches hang out, behind your headlining and in the recesses of the deepest lockers.

Roach motels offer a less dramatic way to attack your unwanted guests. The original Roach Motel was designed to attract roaches, with either sweet-smelling food or pheromones, and to keep them there by the use of something ultra sticky. They go in, but they dont come out! claimed the manufacturer, Black Flag.

How To Protect Your Boat From Spiders

Of all the creepy-crawlies that may come aboard your boat, spiders are often among the least welcome. These many-legged miniature monsters are especially common during summertime when the warm weather brings with it an abundance of food namely, other bugs. Despite their essential role in controlling populations of flies, mosquitoes and other bothersome insects, a spider infestation is the stuff of nightmares for most people!


Whether youre arachnophobe or not, large numbers of spiders can seriously mess up the interior of your boat. This is because, besides leaving webs everywhere, spiders also poop a lot.

Their grayish, brown or black droppings can often be found in corners and on seat covers of boats and will look like tiny dots.

If wiped up immediately, spider poop is no problem. However, if left for long periods of time, these tiny droppings will harden like concrete to form a crust thats almost impossible to shift. Even if you do manage to chip away at the mess, spider poop can leave stains that permanently damage the aesthetic of your boat.

Having large numbers of spiders on your boat can even be a serious health risk to you and your shipmates. Many spider species common to North America can deliver a nasty bite and some, such as the notorious Black Widow, can even be fatal.

So, the big question is how can you protect your boat from spiders? To avoid your boat becoming a web-ridden hellscape, try the following spider control methods for your boat.
